Tetons, trees, bison

Here's a couple of more photos from my travels out west this summer. This is in Jackson Hole, the large valley that abuts the Teton Range immediately to the east. If you've never been to the Tetons, you must go and check them out for yourself. They are an awesome, singular mountain range in the United States. Their shapes and sheer relief remind me of the Karakoram, or Torres del Paine, or some other awesome mountainous region of the world. It's really jaw-dropping.

Here's a shot of the Tetons from the northeast, visually pairing them with a line of coniferous trees in the foreground. Photographically, I like this parallelism in their shapes:

tetons

So what's up with the Tetons? What geologic processes give rise to their readily-apparent awesomeness? There's two main things going on here: faulting and glaciation. First, there's a major normal fault along the base of the range. The Tetons have moved up as a block while the Jackson Hole basin has dropped down as a block. As the rocks of the Tetons (some as old as 2.8 Ga) have been eroded, sediment was generated, and that dropped down to fill in the hole to the east. Jackson Hole is full of of sediment (over 20,000 feet deep), and then the peaks of the Tetons rise an additional 7000 feet beyond that. Based on offset of the Cambrian Flathead Sandstone on either side of the fault, total displacement is estimated to be 30,000 to 35,000 feet (Love, 1987). Even relatively young geologic units in Jackson Hole, like the Yellowstone-erupted Huckleberry Ridge Tuff (2.1 Ma), dip significantly towards the fault (Good and Pierce, 1996). Movement along this fault is ongoing, raising the mountains on average ~1 centimeter per year, with most movement having taken place over the past 9 million years. The Tetons are generally regarded as the youngest range in the Rockies.

Here's a shot coming north from the Gros Ventre landslide area (subject of a future post) towards the main road. A photogenic herd of bison was grazing on the grassy sagebrush flats, purposely maneuvering between me and the mountains so they would have a nice backdrop:

bison_tetons

Once the Pleistocene ice ages began, the tall Tetons accumulated a lot of snow, which packed into glacial ice. Alpine glaciers started flowing downhill, and carving the rock of the mountains as they did so. That created the distinct U-shaped valleys seen in these photos, and left pointy little nubbins between them: the glacial horns like the Grand Teton and Mount Owen. The rocky debris scraped off the Teton block was deposited in Jackson Hole along with till from the Yellowstone ice cap to the north. These piles of glacial till are easily demarcated by the coniferous trees that grow on them, unlike the grasses and sage of the outwash plain.

Cottonwood fluff

cottonowoodfluff3

This was the scene at the campground I stayed at this summer on my first day south from Bozeman to Las Vegas. This is a campground south of Huntsville, Utah, in the Wasatch range west of Ogden (map).

It's not snow you see on the ground, despite being white stuff that accumulated in a layer several inches thick, and blew into drifts like snow would.

cottonowoodfluff4

These are the seeds of the cottonwood tree (Populus fremontii), which like dandelions, have a bunch of fluff emerging from them to catch the wind. This allows the species to spread its range by letting the wind carry its seeds to new locations. While cottonwoods are ubiquitous in wet areas of the west, I've never seen this kind of accumulation of cottonwood fluff before.

cottonowoodfluff2

It was like warm snow -- quite magical to see.

PS - Prius note: The fuel mileage out west this summer wasn't as good as the regular commute back home in DC, but it was still pretty good. The total roadtrip (~10,000 miles) ended up averaging 52.6 miles per gallon of gasoline. Can't complain about that.

Sleepsuit

Look at this wacky thing! I was reading the July issue of the Mountain Gazette this morning (picked it up this summer in Colorado), and was struck by an ad for this thing called the "selk'bag." It's a sleeping bag that you can walk around in. Whoa... futuristic. And definitely kind of dorky. I want one!

Driving through Wyoming

On Saturday, June 14, I drove from Fort Collins, Colorado northwest across Wyoming, ending up just west of Cody in Shoshone Canyon.

Here's a few photos I took along the way:

Hogbacks (or "incipient hogbacks?") north of the Interstate (not sure whether this qualifies as the Laramie Mountains or the Medicine Bow Range, or some other range altogether).
WY_travel_02
Regardless, what you're seeing here is what happens when tilted sedimentary strata are incised by streams. The stream valleys develop at regular intervals along the slope, and notch the sedimentary layers, which themselves have different resistances to erosion. As a result, these triangular-shaped slabs end up poking up along the flanks of the mountains (the Flatirons outside of Boulder, Colorado, are perhaps the best known example).

The Wind River Range appears in the distance. Seeing big bad mountains makes me happy.

Camp at the end of the day. This is at Buffalo Bill State Park, between Cody and the eastern entrance to Yellowstone (Sylvan Pass, subject of a photo I put up yesterday). The body of water seen here is the Shoshone Reservoir. I enjoyed a pleasant evening here of drinking wine, writing a letter, and watching grebes in the water.

Dark clouds came over later, hastening nightfall over the park. Note the addition of the rainfly to the tent. Turns out we just got a sprinkle, no real downpour.

Life on the road is (was) good. Months later, it makes me happy to look at these photos and think about rolling along across the great North American continent, checking stuff out, seeing new places. Classes start on Monday for me, and I'll be locked down in DC for a bit... a fair trade, it seems to me, if my job allows me to go out and see places like these during the summers.

Sylvan Pass, Yellowstone

...No kidding!

This photo was taken in early June, when I drove through Yellowstone for the first time this summer... there was still snow eight feet deep along Sylvan Pass at that time!

Igneous contacts of Boulder Canyon

Today: I offer some photos I took in Boulder Canyon, Colorado, in June. These are all igneous rocks exposed in the Precambrian 'basement' rocks, brought to the surface by the Laramide Orogeny.

Directions: Drive to Boulder; go west up the main canyon into the Rocky Mountain Front Range.

Location map:


Granite pegmatite:

Put the previous two pictures together, and what do you get? My favorite outcrop of the whole excursion... Contact contact! A granite dike cutting across mafic-xenolith-bearing granodiorite. This would be a good practice photo for introductory level students to establish relative ages of the three different rocks shown:

Sauropod tracks at Dinosaur Ridge, Colorado

Brontobulge_1Here's a few photos from the terrific drive-through geology exhibit called Dinosaur Ridge, near Morrison, Colorado (type locality of the Morrison Formation).

On the advice of my friend Michelle, I made a special detour to check out the area on my drive out west in June. It was worth on many levels, but my favorite part of the array of neat geology was this section, where you can see three-dimensional cross sections (if that's not an oxymoron) of sauropod footprints.

The idea is that when these sediments were wet and pliable, adult Apatosaurus (or a similar brontosaur) walked on by, sinking down into the wet sand and mud. Layers of sediment beneath were compressed (as if beneath a dropstone) and then a later deposit of sand filled in the "brontosaur bulges," preserving them. Now they are weathering out of the Dakota Hogback in relief!

Pictures from Mammoth Cave, Kentucky

Now that I'm back in DC, I can actually start downloading the photos I took all summer. Here's some from the first two days of my summer's travels, in Kentucky at Mammoth Cave.

There was a big cicada emergence happening there. This insect is 17 years old!

Cicadas weren't the only wildlife. I also saw a Tyrannosaurus rex in the trees near Cave City.
Dinosaur!

On the Wild Cave tour, we entered Mammoth Cave in a roomy passage, but were soon crawling through very small tunnels...

The Snowball Cafe featured a bathroom, too. I was struck by the contrast between the modern tile and ceramic fixtures and the looming limestone ceiling...

Driving from Montana to DC

Here's a quick recap of my cross-country journey, for those who are interested in such things.

I left Bozeman on Saturday morning, July 26, and drove east on the Interstate to Billings, then diverged southeast towards Little Bighorn. There, I verified a comment from a Lakota friend at MSU that with my new bushy mustache (see change in icon above), I look a wee big like George Armstrong Custer (Custer & his men were killed by Lakota and/or Cheyenne warriors). After a short picnic there, I kept driving across southeast Montana, and into northeast Wyoming. My goal for the night was Devils Tower, where I have positive memories from my "North by Northwesty" roadtrip two years ago. I got to Devils Tower in mid-afternoon, just in time for a wicked-looking thunderstorm to roll in. Pendulous looking mammatus clouds were hanging down, and the skies turned a darker grey than Lola. Rain and wind came through, and a big dead branch from one of the cottonwoods in the campground came crashing down, but not on anyone's car or tent. When the skies cleared up, I drove up to the visitor's center and took a walk around the tower. It's awesome: massive columns, some of them twenty feet across. The rock is a porphyritic phonolite, and it's quite pretty to look at: big feldspars (5mm) set in a fine-grained grey matrix. Lovely.

The next morning (Sunday), I headed for Red Bird, Wyoming (along Wyoming's eastern border), where Cruisin' the Fossil Freeway suggested there would be oodles of ammonites in concretions in the Pierre Shale, some a foot across. When I visited the Denver Museum of Nature and Science earlier this summer, Kirk Johnson reiterated to me that Red Bird was the place to go for ammonites. But once I got to where Red Bird should be (according to my road atlas), there were no highway signs indicating that the town existed. Worse, there were no outcrops, and no sign of public land. (And one thing that an amateur fossil collector does not want to do in Wyoming is trespass on a rancher's land.) So, no Red Bird ammonites for me. Oh well, no worries: I had collected ammonites from a tongue of the Pierre Shale (the Bearpaw Shale) earlier in the summer on BLM land near Glendive, Montana, and scored some good specimens there. I cruised south, stopping at the Sierra Trading Post outlet in Cheyenne, Wyoming, and dropping some cash on some new duds (STP is mainly a catalog business, famous ten years ago for their amazing deals, but the company seems to be shifting to more mainstream business nowadays, including multiple brick-and-mortar locations). Then another hour on the road brought me to Fort Collins, to the house of Larry Wiseman, where I stayed earlier in my trip. He and I got some pizza and 90-Shilling Ale (Odell's) and traded tales about our summers.


The next morning, we had coffee on Larry's front porch and watch the sun rise. I packed up and hit the road, heading for Kansas. In my rear-view mirror, the Rockies shrank and vanished from sight, a melancholy fade. Out into the plains... In mid-afternoon, I rolled into Oakley, Kansas, where I headed for the Fick Museum. The Fick Museum is interesting on multiple levels: it's got some stellar fossils from Kansas's Smoky Hill Chalk (member of the Niobrara Formation), like a Xiphactinus (massive fish) and a Tylosaurus skull (even more massive mosasaur). But it's also got some whacked-out art: the founder, Vi Fick, was into making art with local "art supplies," and so the walls show his portraits of eagles rendered entirely in rattlesnake tails (see image at right, from this online gallery), or his geometric arrangements of thousands of fossil shark teeth. There's even an oil painting Fick did of "God making the Cretaceous seas," which shows a bearded diety surrounded by flames (it kind of reminded me of Hindu art) making pleisiosaurs and pterosaurs. Not the usual way you see fossils displayed, or paleontology depicted!

At the Fick Museum, I met up with Ron Schott, doyen of the geoblogosphere, who graciously agreed to show me some cool Kansas geology. Ron and I headed south from Oakley towards Monument Rocks, an outcrop of the Smoky Hill Chalk. Ron was eager to gigapan the outcrop, and he set up the little device: essentially a robot that directs his camera to take high-resolution photos in a systematic grid. Pretty cool, really -- I guess I hadn't realized what a Gigapan really was before seeing it in action. I got to meet Ron's two little plastic elves that he uses for scale, and personally placed them on a ledge of chalk for the photograph. The grid of pictures eventually gets digitally stitched together by software, and available for sharing online.

From there, Ron and I headed back up to Oakley, stopping en route so I could collect a couple samples of the aquiferiferous Ogallala Formation, and then headed east, then south again, towards Castle Rock, another chalk outcrop. Here, we tested out my Prius' shocks on the dirt tracks, and checked out the largest cliff in Kansas (nearly getting blown off it by the intense wind), and then prospected for fossils below. I found some fish scales, and a shark tooth! Also inoceramid clam fragments, encrusted with oysters (apparently a common feature of the bottom of the Western Interior Seaway). No mosasaurs, though... Back to the road, and into Hays, Kansas, where Ron put me up in his guest room. We had dinner and a few beers at the Lb. Brewing Company, and thought about recording a PodClast, but then it slipped our minds. We discussed field trips, tenure, publications, and related topics. A good time! Thanks again to Ron for being such an excellent host.

The next two days (Tuesday and Wednesday) were essentially just driving. On Tuesday, I made it to Indianapolis, Indiana, and spent the night in a hotel there. On Wednesday, I turned north, and drove up into Michigan, and crossed into Ontario at Port Huron / Sarnia. Why go to Canada on my way from Montana to DC? Well, I'm teaching my Snowball Earth class this week at NOVA, and some of the rock samples I needed were stuck at Brock University in St. Catherines, Ontario. Usually they get shipped to educators who want to use them, but because of alleged border complications, I had to go get them myself; a five hundred mile detour! Fortunately, I have good friends who leave in Waterloo, Ontario, so I went and stayed with them. Mike and Natalie Leuty have been friends since 1996, and we had a good evening catching up. They have a sweet house in a suburb full of professorial types who teach at one of the several universities in town.

On Thursday morning, Mike and I had coffee on his front porch while his kids played in the yard, and then I packed up my kit and got rolling. I made it to Brock by 11am, and got the Snowball Suite. Because it's in a giant black case that looks suspiciously like a rifle case, I packed it under a pile of other gear in my car. At any rate, I crossed back into the United States without any static from customs officials, and rolled through Buffalo, New York (twice in one year!) I made my destination for the night Ithaca, New York, where I have a friend who's going to grad school at Cornell. I've never been to Ithaca, but I hear that it's "gorges" from many people. So I called my friend, Kathryn Werntz, and she was indeed around and accepting visitors, so I drove through the finger lakes region (five subparallel glacial troughs now filled with water), and found my way to her bungalow. Kathryn and I took a walk through Cornell's campus (two amazing gorges cutting through it), had some Indian food, and went to get dessert at Purity Ice Cream.

In the morning (Friday), I got up and we went to Gimme! Coffee for some caffeine. Thus fortified, I hit the road for my final day of driving. East to I-81, then south through Pennsylvania. At Harrisburg, I turned onto I-83, which took me to Baltimore, and from there it was a familiar zoom down the B-W Parkway into northeast DC. The dome of the Captiol was visible to my left, and then the comfortable sights of Florida Avenue and U Street. Up the hill, and a left on Harvard Street, and I was back in Adams-Morgan. Home! Finally!

Long time no blog

Hi everyone! I'm back in DC after a long drive, about which more details in an upcoming post or three. Just wanted to post an update that the blog is back into semi-daily-posting mode, now that I am ensconced back in my DC digs, and able to access a computer on a daily basis. Stay tuned!

The route back to Bozeman

After I got off the river at the Grand Canyon, I drove to Moab, Utah, where I have a friend from my days working outdoor education in southern California. Pete and I went swimming in Mill Creek (water + slickrock = awesome plunge pools) and checked out the sunset from the top of a dome of the Navajo Sandstone north of town. We had dinner at the Moab Brewing Company, which was delicious. The next morning, I checked my e-mail and got an oil change, then went up to Arches National Park to pay homage to Edward Abbey by taking a hike to Delicate Arch. They even have a small exhibit in the visitor center about Cactus Ed -- a nice acknowledgment on the part of the park that his book Desert Solitaire piqued interest in the park for many people.

After my hike, I got back in the car, and headed north to the interstate, then east into Colorado. Past Grand Junction and Delta, to the little town of Montrose, where I got final supplies for a couple of days in Black Canyon of the Gunnison National Park. I pulled in relatively late in the day, so just settled into the campsite. It felt good to be camping at high elevation, with cool temperatures, again. The next day, however, July 4th, I spent in exploring the park. I was surprised to learn that there is no trail down to the bottom of the canyon from the rim, but they do let people descend via "the Gunnison Route," a steep-ass ditch full of loose scree and talus. It was pretty sketchy, and pretty exhausting: not much fun. I kept thinking "there has to be a better way to do this." The reward was at the bottom, where the Gunnison River runs cool and fast. The Gunnison has carved an incredible gorge here: steep, deep, and with a steep river profile. It's a classic case of steam superposition over a buried Laramide uplift. During the recent episode of uplift, the Gunnison cut down through overlying sedimentary strata (including the Entrada Formation's pink sandstone, visible on the north rim) and into the underlying Mazatzal-aged (~1.7 Ga) igneous and metamorphic complex. This resistant rock is what makes up most of the canyon. It looks a lot like the Grand Canyon's inner gorge, with pink ribbons of granite leaping through the amphibolite-grade metamorphics. Anyhow, the river was very refreshing. I rested there for a while, and ate some lunch (tortillas from nearby Olathe, Colorado, wrapped around mozzarella and turkey pepperoni.) The hike back up was a big slog, and about as enjoyable as the hike down ("There has to be a better way of doing this!") Up top, I drove the road along the south rim, admiring the various viewpoints into the chasm and taking small hikes.

The following morning, I packed up camp early, and drove all day. I went west back to Grand Junction, and took a cool little road (Route 139) north over Thompson Pass and through some cool BLM land, replete with pictographs. I got some GREAT gas mileage after Thompson Pass, basically crusing downhill at 100 m.p.g. for over an hour. Awesome! Then through Dinosaur, into Vernal, Utah, and then into Wyoming at Flaming Gorge.

At Rock Springs, Wyoming, I went north on 191, through Pinedale (nearby Fremont Lake is the type location for Pinedale Till, the Rocky Mountain version of the Wisconsin Glaciation), and up to Jackson. Man, Jackson's a tourist trap! Yikes! Not as bad as Vegas, but I definitely didn't linger with the sunburnt hordes there. I had a date with the Gros Ventre landslide. Just northeast of Kelly, Wyoming, this is a classic location in the study of mass wasting events. I camped on the lake created by the 1925 landslide, and spent the next morning photographing the scar and debris pile which dammed the Gros Ventre River. Unlike the Madison River's landslide and resulting "quake lake," no one was killed with the initial earth movement at Gros Ventre, but when the dam failed two years later, the resulting flood drowned six people in Kelly. I first learned about the Gros Ventre slide as an undergraduate, and I teach about it today, so it was a real pleasure to see it firsthand.

Next morning, a ho-hum commute through Grand Teton and Yellowstone National Parks and up into Bozeman.

Rafting the Grand Canyon

Sorry for the long delay in posting here. Turns out they don't have Wi-Fi at Phantom Ranch.

After my time in Zion (did Angels Landing and a few other small hikes while there), I scooted down to Las Vegas, Nevada, to pick up my father and two brothers. They had flown in there, and after one day were already tired of the city. I was ready to leave five minutes after I got there, which is always how I feel about Vegas. Somehow, circumstances keep conspiring to bring me back there, though...

We drove out of the Basin & Range and up onto the Colorado Plateau, and spent the night at Cliff Dwellers, a lodge near Marble Canyon. I was really impressed with their food and drink. We had an amazing meal, washed down with several pitchers of Newcastle Brown Ale! In the morning, we gathered up our gear and put onto the river. Our trip consisted of two rafts outfitted with side tubes and motors and guides. One raft was entirely made up of a family from Charlotte, North Carolina, including the glass artist Wayland Cato, III. The Bentley's raft was augmented by a family from Littleton, Colorado, two oil men from Oklahoma, and a couple of veteran river rafters from northern California. It was a motley crew, but we started having fun immediately.

We launched at Lees Ferry, in the Kaibab Limestone, and then descended in both elevation and geologic time. At our first lunch stop, in the Coconino Formation, I was astonished at several synapsid reptile trackways protruding from the underside of the paleo-dune slipfaces overhead. I took some photos, but because of the aforementioned software issue, I won't be able to share them until I get back to DC in August. As the first couple of days went by, we just went deeper and deeper into the Paleozoic stratigraphy of the Colorado Plateau. Of all the formations, my favorite was the Bright Angel Shale, which has many beautiful colors in thin layers throughout (not to mention oodles of trace fossils). I was particularly pleased to play frisbee in a "cave" in the Redwall Limestone, a place that I have shown photographs of to my students, but never actually seen before. It's a HUGE cliff of the Redwall, and then this seemingly small cave etched into its base (and filled with sand), but the cave could easily swallow my building at NOVA: it's big!

At some point, we crossed a major fault, and were instantly dropped down about a billion years in geologic time. Once we got into the Grand Canyon Supergroup and the metamorphic and igneous basement rocks, my geologic interest really went wah-wah. The Vishnu Schist and Zoroaster Granite make a stunning contrast: really beautiful pink cutting across dark grey. I introduced my raft-mates to the idea of the Mazatzal Orogeny, and we discussed how boudinage forms. There were faults and folds galore: structural paradise. I loved it.

Did I mention the rapids? There were rapids. The water was COLD, thanks to Glen Canyon Dam(n). But the sun was hot, and we dried out quickly. Meals were gourmet, though the campsites were spartan (you had to poop in a box that got packed onto the raft each morning: leave no trace!). We slept out under the stars every night, sometimes dealing with blowing sand.

We took several hikes up side canyons to see waterfalls and go swimming. Several of these were good and physically challenging, which is what I wanted. I enjoyed swimming and playing "three-dimensional frisbee" in Havasu Creek, and doing cannonball jumps in the weird blue of the Little Colorado River.

The final day on the river, we came to the western section of the Canyon where recent lava flows (basalt) have cascaded over the rim and down into the canyon. This is famous for producing one of the toughest rapids in the whole Grand Canyon: Lava Falls. But it was awesome to float by and see umpteen gazillion columnar joints, and whole feeder canyons plugged up by basalt. Pretty cool!

Our final morning, we were helicoptered out of the Canyon to a ranch on the rim. This was my first time in a helicopter, and it was giddy and amazing. I want to fly! From the ranch, we transferred to small fixed-wing planes, and I said goodbye to my family. They went back to Vegas, and I flew back to Cliff Dwellers, where my Prius (and a shower!) awaited.

Bozeman to Zion

I left Bozeman on Saturday morning, and drove for about seven hours. I headed south through Ennis, Montana, along the western side of the Madison Range, passing by the Madison Earthquake Site landslide (from the 1959 Hebgen Lake earthquake), and then south into Idaho. I went through Island Park, Idaho, site of the caldera of one of the three big recent eruptions of the Yellowstone volcanic center. Then into northern Utah, where I got a glimpse of the Great Salt Lake. I headed up into the Wasatch Range to spend the night, just east (and several thousand feet above) Ogden, Utah. I did some birding on the reservoir there, observing the mating rituals of both the woodcock (amazing humming noise produced during flying dives) and the western grebe (neck bobbing following by synchrnonous running across the water).

The next morning, I headed west from there, into the basin, across a range, into another basin, across another range -- you get the idea. I initially intended to go hunt for trilobite fossils in the Wheeler Shale in the House Range, but the 20-mile dirt road rattled me (quite literally) and I turned around after only four miles. I got spooked: what would happen to me if the Prius broke down out here? It's really quite desolate country. I've only ever had that feeling once before, when my Dad and I drove across the Namib Desert. It's a mix of agoraphobia and anxiety over feeling inept at repairing mechanical things, like Prii and other automobiles. I chickened out -- no trilobites for me. But there was a consolation in Great Basin National Park, which was where I headed that afternoon. I did a short hike there in the Snake Range, and toured Lehman Caverns there (my third guided cave tour in two weeks!). I had my best campsite of the trip at Great Basin: montane forest, with a gurgling stream running fifteen feet from my tent. Lovely.

When I woke up, I packed up the car and coasted downhill for eight miles into the town of Baker, Nevada, where I had a great breakfast and coffee at a little cafe there. Then up and over the Snake Range, and down the next valley to the west, south for 93 miles of some of the most empty country I've ever seen in America. In an hour and a half of driving, I saw only 20 vehicles. I crossed back into Utah, and then made my way south to the edge of the Colorado Plateau, and drove up into Zion National Park. Zion is a great canyon cut into a series of sedimentary rocks. The last time I was here, 13 years ago, I walked up the Narrows, and my first order of business was to repeat that hike. There's a new shuttle system in the park now, so after parking at my campsite, I hopped on a shuttle into the park and rode it to the end. I waded into the Virgin River and shuffled upstream. In the Narrows, the Virgin River has cut down through the Navajo Sandstone, but not quite down into the weaker underlying Kayenta Formation, and so the canyon is deep but narrow. (Downstream, when it gets deep enough to tap into the Kayenta, it undermines the sandstone cliffs, and the valley widens.) "Hiking" here is one of the more unique outdoor experiences I've had. Being immersed in the cool river, surrounded by towering rock walls -- it's magical. The further upriver you hike, the less people there are, and it's like a cathedral. I went up and around several entrenched meanders, and marvelled at the alcoves, cross-bedding, and variety of cobbles in the riverbed.

Today, I'm staying in the park and heading up to Angel's Landing, a legendary hike in its own right. Tomorrow morning, bright and early, I'm off to Las Vegas to pick up my Dad and brothers for our Grand Canyon rafting trip. Not sure if I'll be able to post again until after I get out.... late next week.

The rest of the way

Sooo.... I've been "delinquent" about posting (if five days off counts as delinquent). But the long and the short of it is that I made it to Bozeman, and started classes, and have settled into life up here. After leaving Denver, I spent a couple days in Fort Collins, Colorado, staying with my undergaduate mentor professor Larry Wiseman. When I was at William and Mary, I forged a strong relationship with Larry, and that persisted even though I defected from biology (he's a developmental biologist, and chair emeritus of the department there) to geology (basically because they had more field trips). Anyhow, he and I would gather once a month or so for coffee and talk about life, the West, Ed Abbey, art, and science.

Now he's retired and pursuing bird rock art and also teaching cell biology at Colorado State University (in Fort Collins). We drove up to Rocky Mountain National Park and toured the various microbreweries and restaurants of Fort Collins (and Lyons). It was, in short, a good time.

Departing there on Saturday morning, I drove north through Wyoming, and camped at the end of the day at Buffalo Bill State Park, on the east flank of Yellowstone. On Sunday morning, I drove through the park, marvelling at six-foot-deep snow on Washburn Pass, and cruising along past tourists and bison galore. I stopped once, to look at the single petrified tree there, and then rocked and rolled on up the Paradise Valley to Livingston, and thence westward on the interstate to Bozeman.

In Bozeman, I'm enrolled in the Master of Science in Science Education program at Montana State University. It's essentially all science educators who are taking graduate coursework to become better science educators. And it's fun! This week, I'm taking Dave Lageson's class on the geology of the northern Rocky Mountains. More on that later, perhaps, but the point for now is that I'm enjoying it, and enjoying interacting with my fellow MSSE educators.

Tonight, I had a bonus, when we had a mini-conference of geobloggers. I guess there's somewhere around 50 geobloggers out there now, but we had four of them sitting at one table in Montana Ale Works, talking rocks and fossils and blogging and whatnot. That's got to be a record for the geoblogosphere. It was a lot of fun. Thanks to Mel, Brian, and Jeannette for making it happen!

A great day of paleo

Roadtrip update:

Yesterday was a good one. I started off the day at the Sternberg Museum of Natural History in Hays, Kansas. I was the first one in the door, and had the place essentially to myself. Massive mosasaur skeletons, supercool Uintacrinus slabs, plesiosaurs, and all kinds of other neat stuff. They had some less spectacular mineral displays, but the locally-derived fossils were world class. I was very impressed.

Then, driving. I made good time when the wind wasn't trying to stop me, and listening to Bill Bryson's A Short History of Nearly Everything on my iPod, I crossed into Colorado. Eastern Colorado looks a lot like Kansas, of course, but before too long had passed, I got my first view of the Rockies in the distance, "rising from the plains." I got to the Denver area around 2pm, which meant I had plenty of time before the 7pm "Geography Goes Digital" event at the Denver Museum of Nature and Science (DMNS). So I headed southwest, towards Morrison, Colorado, and "Dinosaur Ridge." Dinosaur Ridge is a hairpin driving loop on/over the Dakota Hogback, showing Mesozoic sedimentary rocks shed off the Laramide Orogeny and into the Western Interior Seaway. There's an excellent display of dinosaur tracks, and lots of cool ripple marks, trace fossils, concretions, and stratigraphy. Looking out over the crisp dry air of the Denver Basin, I really felt like "Aha! I'm finally in the West!" It was a good feeling. After hiking and exploring there, I toodled into Morrison, Colorado, and went the Morrison Museum of Natural History. There, I had the terrific good luck to run into Matt Mossbrucker, who I mentioned reading about in Smithsonian magazine back in April. The museum's volunteers were on vacation, so I had the good fortune to have a personal tour from the director! Matt showed me a wealth of incredible fossils, including the type specimen of Stegosaurus, and footprints of baby Stegosaurus and Apatosaurus -- the latter tracks were the subject of the Smithsonian article. In case you (still) haven't read the article, it looks like these baby sauropods were capable of running on their hind legs like a basilisk lizard. Matt walked me through the logic, pointing at specific pieces of evidence on the massive slab of rock. Then we were out of time, because I had to get over to the DMNS for the "Geography Goes Digital" event.

At the DMNS, I was met by Kirk Johnson, the author of a book I mentioned here a month or so ago: Cruisin' the Fossil Freeway. My friend Michelle knows Kirk, and put us in touch. (Thanks, Michelle!) Kirk has been at the DMNS for more that fifteen years, starting as a curator of paleontology, and now as a vice-president. It was very cool of him to make time to see me. Immediately, Kirk introduced me to Bob Raynolds, the speaker for the "Geography Goes Digital" event. Bob and I talked a bit about geology and teaching, and then we scooted over to the Planetarium for the main event. I took a seat, leaned back and was amazed. It was like Google Earth on steroids; a feeling like looking down from the space station on Earth. Bob led us on an exploration of areas of the world that are showing the strain of coping with climate change. He has an astonishing amount of geographical knowledge (apparently, he has traveled to more than 50 countries to do geology) and it was a real treat to tour the planet with him and 150 of the DMNS's closest friends. Afterwards, Kirk took me and another friend-of-a-friend visitor on a tour of the museum. I saw the world's second-largest gold nugget, a massive crystal of rhodochrosite, and the incredible tour through time exhibit that Kirk put together when he first got to the museum. Starting with the Ediacaran, the exhibit went through time in a series of sub-exhibits. Each started with a diorama, and then showed the fossils that the diorama was based on. There were some INCREDIBLE fossils there -- absolute stunners. Kirk confided that's just how he wanted it -- not a thousand small fossils, but a few massive ones that just knock your socks off. It was very impressive. Around 10pm, I bade Kirk farewell, and left the museum. I drove up to Boulder, Colorado, and holed up in a hotel for the night.

I feel really lucky to have visited three amazing paleontological museums in one day, and to have had personal tours from the elite of Denver paleontology. Many thanks to Matt and Kirk for making time to show me around!

Now I'm off to check out Boulder, and maybe hike in the Flatirons above town. More later.

Roadtrip update

Howdy folks,

I've been on the road for several days now, and thought it would be time for an update. On my first day, I got up at the crack of dawn and drove from DC out to Winchester, Virginia, where my brother lives, and had breakfast with him and his family. After saying goodbye to my passel of nieces, nephews, and the dogs Cubby and Slick, I hit the road proper. Down the Shenandoah Valley on I-81, then west on I-64 across the wide part of West Virginia. This was the Valley and Ridge province, and it's hell on the gas mileage. I dropped from 54 mpg to 53.5 by the time I got out the Allegheny Plateaus. I also saw the most expensive gas I've seen so far: $4.75 a gallon for regular unleaded. (The lowest I've seen is $3.78.)

After crossing the border into Kentucky, I deviated to the south, and around 8pm EST (7pm CST), I pulled into Mammoth Cave National Park. I got a campsite, set up the tent, and popped a bottle of homebrew. (I brought my last six bottles of Whatchagot Ale with me.) There was a racket coming from the trees: a 17-year cicada emergence was in progress, and the seething insects pulsated as they coordinated their shrill call: positively primordial. For my evening's entertainment, I attended the Park Service's "campfire" program. (Today, "campfire" means "PowerPoint slideshow," which has its advantages and its disadvantages.) It was a hot and humid night's sleep.

The next morning, I got up and made some coffee. After breaking camp, I took a hike down to the "River Styx," an emergent spring where a stream of water flows out of Mammoth Cave and into the Green River (the same Green River, by the way, of John Prine fame). I also passed one of the many entrances to the Mammoth Cave system, and felt an amazing cool breeze oozing out of the hole and flowing down a classic solution valley towards the Green River. At 10am, my tour of the cave began. Mammoth offers multiple tours of different parts of the cave at different activity levels. I signed up for the gnarliest one on offer: the so-called "Wild Cave" tour. (Tuff Cookie presciently recommended this to me, though I had in fact reserved it a couple of weeks ago.) The Wild Cave tour is different from most Mammoth tours because it's real caving, with crawling and mud and tight squeezes, and climbing skills. You've got to be reasonably fit and trim for the Wild Cave tour to work. Joining me where 11 other people with various backgrounds, including seven from the ESPN auto racing circuit. They had a fun, jocular attitude, with a lot of mutual joshing and teasing.

I was struck by a few things about Mammoth: (1) It's really big. But that's why we bother going there, and why it's a national park (it's the longest cave system in the world), so this is no big insight. (2) It's got a lot of gypsum in it. In many places, "flowers" of gypsum crystals sprout from the ceiling and walls. I asked, where's the sulfur coming from? The guides said there was a pyrite rich layer above, which was being leached by rainwater. (3) There's not a lot of stalactites in Mammoth. I've spent a lot of time in caves in West Virginia, and there are many places in them where it's nothing but stalactites. I'm not sure what's up with that, but it was noteworthy to me. (4) There are some HUGE rooms in Mammoth, with ceilings that are easily five or six stories tall. Very impressive; cathedral-like. (5) Mammoth Cave has been a tourist destination for a LONG time. People have been trekking to this destination long before there was a road network to bring them there. Back in the day (late 1700s and early 1800s), people arrived via the river rather than overland. Some of the cave was developed early on to support these visitors. Nowadays, the Park Service continues this tradition with paved walkways, lighting, and even a subterranean cafe in "sacrifice" areas of the cave. My tour passed in and out of these areas throughout our six-hour expedition.

After exiting the cool cave back into the Kentucky afternoon heat, I took a shower (the best $2 I've spent so far on the trip!) and popped into the Prius for some more driving. I headed north again, crossing briefly into Indiana, and then Illinois. I spent the night at a hotel near Mt. Vernon, Illinois. Yesterday morning, I got up and drove west all day, back on I-64 and then on I-70. I crossed the Mississippi River at St. Louis, and then crossed Missouri. Into Kansas after that: it wasn't nearly as flat as I remembered it. Part of the insight into Kansas' topography was courtesy of the Prius, which showed me (via the mpg indicator) when I was going uphill and down. A strong headwind lowered my fuel efficiency significantly, dropping it down to 52.7 mpg by day's end. There's a lot of wind out here! I was also struck by the clouds: such crazy, distinctive forms. I can see how if you were growing up here, you could get into meteorology big time. I saw a massive storm system to my south, and the local NPR affiliate was broadcasting storm warnings and tornado watches all afternoon.

I decided to stop for the night in Hays, Kansas, home of fellow geoblogger Ron Schott. As it turns out, Ron is not actually in town this week, but I may be able to hook up with him for some Kansas chalk scouting on my way back east in late July. But there's a lot to do in Hays. For dinner, I went to the Lb. Brewing Company, a craft brewery and brewpub downtown. I got a sampler of eight (small glasses) of their various beers, and enjoyed them all. Most unusual was a lemon beer which tasted a lot like lemonade. After dinner (reading Oceans of Kansas with my turkey panini), I watched another massive storm system pass to the north, with towering gray clouds and sporadic pulses of lightning. Wow.

This morning, I'm off for a run (need to stretch those legs!) and then to the Sternberg Museum of Natural History here in Hays (an affiliate of Ron's university, Fort Hays State University). The Sternberg has a reputation as having awesome fossils from the area's sedimentary strata laid down in the Western Interior Seaway. Looking forward to it.

Next stop: Denver, hopefully by 7pm so I can attend the "Geography Goes Digital" event at the Denver Museum of Nature and Science. More later...

Lola and the maps

I leave this weekend to begin a two-month trip out west (Montana mainly, but also Grand Canyon and points in between). As I'm prepping for the trip, my cat Lola has been sabotaging my efforts to plan. Though I've reassured her that she'll get along great with my subletter, she is still obsessed with blocking my trip-planning progress.

Here she is lying on the roadmap of Colorado:

lola_roadmap

And here, covering the "explanation" for a geologic map of the states of the stable interior:

lola_geol_map

I love that my job allows me summer travel time, and I love that, living in DC, I can get a subletter to take over my rent and cat care during the time I'm away. But I will miss this little furball when I'm on the road. She's a great cat.

Horseshoe crabs of Delaware Bay

Yesterday, I went up to Delaware Bay to help the Nature Conservancy count spawning horseshoe crabs. I carpooled with my student Efrain and his friend Dennis. We did some birding at Cape Henlopen State Park, then had dinner and a few crafty craft beers at the Dogfish Head Brewpub in Rehoboth Beach (I had crabcake, natch.), and then headed out to Big Stone Beach for the main event: the spring tide and the new moon mean spawning horseshoe crabs (Limulus polyphemus) by the thousands. We were helping the Nature Conservancy tally up the numbers of male and female crabs. You can learn more about horseshoe crabs at this excellent website. Or you can just look at these images:

...You get the idea. Other images on the Flickr photostream. Joining a couple of medical doctors from Delaware (well, originally from Virginia, but stationed in Delaware), we surveyed the beach using TNC's rope and square-meter protocol. The weather turned cold and rainy, but we kept it up, and saw a lot of crabs. I estimate that altogether, we saw somewhere around 5,000 crabs. Pretty cool: one of the great wildlife concentrations in the world, and it's only 2.5 hours from DC. Next up: sandhill cranes on the Platte River in Nebraska, or maybe polar bears in Churchill, Manitoba...

Typhoons I have known, part 1

With all the news this week about Tropical Cyclone Nargis in the Indian Ocean, I'm struck by the lack of analysis by the geoblogosphere. Though I personally know no one in Burma, I have friends in nearby Malaysia. The 10,000 projected death toll from this tropical storm is tragic -- and entirely predictable. Tropical storms and low elevation population centers do not make a happy mix. As the human population of our planet grows, I reckon devastating events like this will occur with greater frequency, even independent of any climate-change-induced increase in frequency or intensity of the storm itself.

Typhoons, cyclones, and hurricanes are all the same thing with different names based on which oceans they happen to develop in. To help share some perspective on what one of these things feels like, I thought I would share my experiences sitting through two of them: a typhoon in the Philippines in 2001, and a hurricane in DC in 2003 (Isabel, pictured above).

I'll start with my time in the Philippines (excerpted from my complete account of the Philippine trip). I was there visiting my friend Noah (who was then in the Peace Corps on the island of Panay). As this image of Pacific Ocean typhoon tracks shows, a lot of those storms cross over the Philippine archipelago:

Some background on the excerpt you're about to read: Noah was working as an environmental volunteer on the island of Panay, southwest of Manila. I've included a couple paragraphs below on the day we arrived on Panay, and then an extensive description of weathering the storm. The storm was only half of the trouble: there were also complicated social issues in Noah's life at this time. Specifically, he had just moved into a new beachfront house ("the nipa hut") and inherited some grouchy pets and expectant neighbors from the previous owners. Also, an ex-coworker and ex-romantic interest had invited herself to stay with him, and that made for a sticky situation. Anyhow, I guess I'll just let you read all about it:

Like any third-world den of squalor, Kalibo had a petrol fume/human excrement stink to it. The town was drier than Manila, but with much more exhaust and dirt in the air. I was glad when Noah arranged a ride on top of transport bus to Pandan, his village. Riding on top of that vehicle was an experience I will never forget. At first, I was thrilled by the air, the views of paddies, and bamboo and palms. Farmers were threshing rice by hand, drying rice on the street, planting new rice behind a plow pulled by a carabou, the ox of the Philippines. As we rode, I gripped tie-lines that held in place a half-ton of luggage and supplies. These sacks and boxes were lashed to the roof of the bus, and Noah and I and five other men were clinging on top of it all. Soon a few drops of rain began to fall, and the temperature cooled noticeably. There was a gray wall of clouds ahead of us, and it looked like thunderstorms to me. Noah shouted something to me that I couldn't quite make out: it sounded like he said "typhoon." The raindrops increased in frequency and decreased in temperature. I put on a pair of sunglasses to protect eyes, in spite of my giddy desire to see as much as possible.

Two days before I had been back in America, packing up my classroom, getting coffee with my girlfriend, and now I was here. Surreal, I thought, gripping the wet guy-lines, atop a bus, hurtling down a mud road on a minor island in the Philippines, rain lashing my face. We rigged up a tarp to protect us from the cold rain, and in the lee of its shelter, we made it comfortably to Pandan.

...

That was the day that the typhoon started.

The "persistent breeze" that had been blowing from the southwest intensified through the course of the day. It was a sort of wind that we do not ever experience in North America. This typhoon wind was steady and constant, not gusty. It just continued to blow and blow and blow, hitting the beach at Pandan head-on; the shoreline perpendicular to the main force of the wind.

The rain came in mid-afternoon, joining the wind by degrees, until at sunset, the two were one: an unvarying horizontal threshing of droplets. The palm trees were all bent back, giant fronds splayed towards the northeast, like spiky-haired tykes squinting into a powerful hair drier.

Just 8 degrees north of the Equator, the sun sets early in the Philippines. Or rather, it sets "early" to my summer North American perspective. Bear in mind, I had come from DC, where the sky stays light in summer until almost 10pm. Here there is less variety; year-round, the sunset comes between 6 and 7pm. While the day began with a spectacular sunset as I swam in the ocean and heard Noah recount his traumatic evening, it ended with a dull fade-out. The lashing rain diluted any view of the sky or the horizon that we might have had. It just changed from light gray, to dark gray, to darkness.

I sat in the nipa hut in the darkness, thankful for the electric light that allowed me to stay up writing and musing on this new storm. The same wind that had been blowing all day was still blowing. The same rain that has been falling all day was still falling. Steps on the bamboo deck outside shook the house, and the door opened in a splatter of droplets. Noah had returned from town, and he yanked back the hood of his Gore-tex jacket, revealing a large wet grin. "It's officially a typhoon," he told me. "The whole town is talking about it."

There is a mesh windscreen in front of Noah's house, but the wind and water come through it with ease, and the beach-front side of the nipa hut was already sodden. The back of the house, facing inland, towards town and the mountains, is in the lee of the wind. I was surprised to find it was completely dry there, and even for several feet extending back, in the "wind-shadow" of the house. This evidence convinced me that the wind really had not changed direction all day. I was reminded of the act of spray-painting a textured object, where shadows of unpainted areas extend beyond any raised obstacles, fading at their edges into the exposed areas.

In the nipa hut, we had moved into fortress mode. All the windows facing the beach and the force of the typhoon had been shut, resulting in a greater than usual sense of darkness in the house. We had a few windows open on the leeward side of the house, thankfully, admitting light and fresh air. There was a constant "white noise" roar outside the walls: the sound of furious but constant wind tearing through the coconut fronds.

It had been an odd day. We three (Noah, his ex-paramour Zita, and I) had spent pretty much the entire day at the house. In fact, Zita had not left at all, not beyond the porch. The unceasing rain coupled with Noah's urge to "nest" as a new homeowner kept us on the property. I took the opportunity to do some reading. I read through Pico Iyer's perspective on the Philippines in an essay included in Video Night in Katmandu, and an ecological history of these islands titled Plundering Paradise.

Noah and I walked into town in mid-afternoon when we were both getting a little stir crazy. Also, we needed to talk out of earshot of Zita. [She wanted some nookie from Noah, but he wasn't interested!] We bought some hardware and some random fruits from the market. When we got back to the house, we sampled guava, mango, avocado, breadfruit, and santol: a nice filling little frugivorous feast. But out on the road, hunched under our Gore-Tex hoods, we discussed the situation back at the house.

Zita was being a sullen sloth. It was incredible to see how starkly her personality imploded. I compared last night's devil-may-care rash party animal with today's sleeping grouch. All day she had been laying around sleeping in the dark house. ...I was sure that Noah's rejection of her advances led to her sour mood. When she was not asleep, she wrote silently and fiercely in a small journal.

She was not speaking much to me, and only marginally more to Noah. He had been polite to her all day, but kept taking every opportunity to try and convince her to leave. Cultural conflict was swollen in this situation: it's the Filipino way to host a guest as long as they wish to stay, but it's obvious to me that the situation was tense in this small little house with such foul weather outside, and her taking up all this space and energy by hanging around. Both Noah and I wanted to be rid of her. The longer she stayed there, slumbering in the middle of the room where Noah and I were trying to get things done, the more frustrated we became. She was dampening the mood, and making me nervous: I had seen the energy she was capable of the previous evening, and now I was seeing the sullen grade of her fury. Would she lash out? Would she burn down the house? My God, what to think? How to get her to leave, culturally sensitive or not? She didn't even wake up to eat the dinner that Noah and I made: banana shoots and squash in coconut milk curry.

Noah asked me to sleep in the same room as them that evening as a deterrent, which I did. Roaring of wind and rain when I fell asleep, roaring of wind and rain when I woke up.

Day Two of the typhoon was a lot like Day One. The storm raged through the night, and continued unabated. In fact, it intensified in strength, though the unidirectional wind remained unaltered. The electricity had died during the night, some wire blown down somewhere on the island, wherever it came from. I had seen the haphazard wires in the trees, and I guessed that we wouldn't have power for a while. I was right. Stepping out onto the deck, I was shocked.

The ocean had come up almost to the house! A furious whipping surf stretched from a few meters away, to a distance of about two hundred meters offshore. It was an incredible sight, and I thought first of running. But, as I stood there observing, I realized that it was holding steady, at least in terms of the reach of the waves. The whitewater was solid, a strip of froth as wide as an interstate freeway, running up and down the shore as far as the eye could see. The eye, incidentally, could not see all that far: the raindrops were thick in the air, and all images faded to gray before they were a quarter-mile distant.

Slack-jawed and breathing hard, I stared at this raging ocean. I was squinting, of course, since the wind and rain were coming straight in at the house. And it was loud: the constant roar of wind and waves had not faded nor paused for a full day. The beach was but a sliver. As I watched, a strong wave breached the storm-shield mesh screen. My eyes popped: I had never seen a storm like this before, never seen the sea so churned up.

I worried about the integrity of Noah's house: obviously the thin bamboo structure would quickly disintegrate under a pounding from these waves. The question was: would the waves actually reach the house? Another one washed up past the netting and coconut fronds of the storm shield, curling white foam like a tentacle around one of the porch supports.

Across the way, one of Noah's neighbors was wearing a green "hard-hat" helmet as he readied his homestead for the onslaught of weather. I guessed that this was to protect his head from stray coconuts that might be dislodged from above by the winds. He and his sons were pulling in one of their large V-shaped fish traps, trying to get it out of the greedy reach of the waves.

I go back to the nipa hut, where I find Noah on the porch, and he says to me, Whoa.

We go inside to make some coffee. Zita is (of course) still asleep. I see that the cat has returned from its hermitage hideout (wherever that may be), and has snuggled up next to Zita. Perfect, I think, they deserve each other.

I'm really glad that Noah is as much an aficionado of coffee as I am. We use his French press and some coffee beans from the southern Philippine island of Mindanao. We can't sit outside because the rain has again started in earnest. We aren't comfortable in the main room, because Zita is still sleeping in there. So we end up standing in the kitchen, which is actually about the size of a closet. There is enough room for two men to stand there, but a third would be too much. We stare with eyes that are at once revelatory of the stress of Zita's presence, of the ocean that threatens to engulf the house, and our cramped quarters while drinking our morning coffee. Our eyes reveal fear and frustration at the predicament. We stare, then laugh. Pure comedy.

As the day goes by, I adopt a Zita-like strategy of staying indoors as much as possible. However, I start feeling tinges of cabin fever. I watch Noah cope with the stress.

He tried to coax the other abandoned pet into the house for some food. This was Maggie, the dog foisted off on Noah by [the previous owners] when they left. Maggie hates Noah. He was bitten twice by the dog: once on each hand. The dog was freaked out, unhappy, abandoned and well aware of it.

As Noah was pouring Betadine into his cuts, his neighbor Linda came over. She apparently had a good relationship with the former residents, and accepted some pay to do their laundry for them. She didn't waste any time asking Noah if she could borrow money. He had to turn her down.

I can tell by Noah's lip-smacking mannerisms that he is perturbed. He has a lot to cope with at the moment: the storm, the mooching neighbor Linda, Zita intruding on his home territory, the new house itself, work, and even my own presence as a guest and therefore as added responsibility. He remains calm, but he is not his usually exemplar of happy ebullience. This reminds me of my own Peace Corps experiences in Mongolia: attempting to deal with ten issues at once. It is taxing.

I step outside during one of the drier lulls in the storm. The wind never quits, but sometimes it carries more water with it, sometimes less. There is an immense pile of coconut husks, bamboo, fronds, and colorful trash piled up next to Noah's house: pushed there by the largest waves. Indeed, as I watch, another one washes up past the fence, into the yard, and under the porch.

During an especially strong gust earlier in the day, one of the four main supports for the storm-shield had cracked, and slumped against the house. The mesh slumped and whipped in small rivulets as the wind pummeled it endlessly. The bamboo that had cracked was a good five inches in diameter, substantial and strong. I was thankful for the presence of the storm-shield; I supposed that had it not been there, that damage would have fallen to the house itself.

Among the deposited flotsam, I saw a large pufferfish. It is dead, a big flabby bag-like fish, with an immense clean white beak, like a parrot's. I beckoned Noah outside to investigate with me. He picked it up: a heavy sodden corpse, with scaly jowls shaking. We used the bizarre creature as a prop for some photographs, excited by this minor event in our otherwise boring day spent indoors. Noah, taken with a halfbaked inspiration, took the fish over to the neighbors who earlier had solicited him for a loan. They refused, claiming it poisonous. Ah yes, so this was fugu, the species that the Japanese prepare to eat. Specially licensed chefs prepare the fugu, avoiding the toxic glands. Invariably each year a few meals are botched, and a few Japanese gourmands end up on the floor of the restaurant dying, twitching as the neurotoxins take hold. We toss the dead fish back into the surf. We (ahem) do not have to walk far for this task.

Somehow, the weird fish brought back our sense of humor for a while. It felt good to be outside, away from grouchy Zita, in the fresh air, stretching our legs.

We joked and laughed and squinted into the wind. Then the rain started pelting again, and we yelped and ran for cover.

Back inside, Noah gleaned some facts from the radio: it's a Signal One typhoon, the mildest incarnation of the five-part scale. I could imagine a storm being worse than this, I guess, but my imagination stops at Signal Three. What a Signal Five typhoon would be like, I have no earthly clue. It must be horrendous, and must strip the islands clean of anything on them. Despite the low classification, the winds in excess of 150 k.p.h. have earned this storm the classification of "supertyphoon." Also, there are the first reports of casualties: two men from Pandan died when their fishing boat capsized several miles out. The radio also reminded us that today is July 4th, American Independence Day. No fireworks for us tonight.

Cabin fever had set in full by the end of the second day. 48 hours is a long time to spend in a bamboo cabin with your friend, a sleeping dog, a piss-ant cat, and a woman scorned. I tried to relieve my inner tension by doing push-ups in the storage room. It helped for a while. The electricity was still out, and the routine of sitting, reading, writing, talking, eating, and sleeping had begun to chafe.

In the late afternoon, the rain eased again, and I elected to take a walk. Noah had taken a break from his efforts at attempting to indirectly convince Zita to leave, and had gone to a meeting; Zita herself was writing in her sullen notebook. I donned my raincoat and whistled up Pawikan the dog. The gate to Noah's yard had been sealed shut by the accumulation of wave-borne debris outside, so we had to squeeze through to exit. Off on a stroll through the typhoon!

The sea had receded a bit, and the beach was again revealed to us to walk on. The sand was dark and firm, the mountains obscured by the gray mist and clouds. As they had been for days, all the coconut palms and nipa fronds along the beach were bent inland, as winds continued to blast in unceasing from the south. But precipitation was light, and Pawikan and I enjoyed the stroll west along the coast of Pandan Bay.

There were some terns with forked tails in the air above the waves. How these birds were managing to fly in this wind was beyond my comprehension: I could only just manage to walk!

We reached a gravel bar where a river flowed into the bay. Huge clots of vegetation were bobbing down the swollen river, more mast for the re-depositing powers of the sea. I threw a stick for Pawikan, but he showed no interest. We turned around and began to meander back.

Almost immediately, a new squall blew in. I was pelted with horizontal rain that stung my skin like gravel pellets. I was exceptionally thankful I had my raincoat with me, and I pulled the hood sideways over the right side of my face. I began running, and Pawikan needed no further cue. The dog ran much faster than I was able to go, and periodically he hid behind palm trunks and clusters of nipa. When I caught up to his position, he would sprint for the next shelter. Shelter doesn't mean having a roof above your head, at least not here: it means having an object between you and the sea! The equation for the Philippines is: Horizontal rain = horizontal shelter.

I got back to the house feeling really good, exhilarated by my small adventure. I took an extended shower and dried off and felt clean and exercised and contented. An evening cadre of guests gathered in Noah’s house: Boy, Zita, neighbor Linda, Bimbot the veterinarian, Noah himself, me, and the wet Pawikan, who was enjoying a scratch from his owner. The grayness outside faded to black, and another day had ended. Still the storm continued; I was exasperated: this was so unlike the summer afternoon thunderstorms that I have been used to in DC and Virginia.

At some point, Noah and Zita talked and reconciled their silent conflict. We bought some San Miguel and stayed up a while, listening to the BBC. Zita had cheered up, and again I was shocked to see the 180-degree change in her personality. She was again an extrovert, calling the beer by nicknames like "SMB" and "Vitamin B1." We had a good time together, the three of us, more relaxed than in days. The storm reflected the change, and though it could only be described as "a dark and stormy night," the roar has abated from freight train to mere Mack truck.

Like a fever, on the third day the typhoon broke. I went out to the beach at dawn, and found myself one among many. Up and down the beach, people were out surveying the da
