Geologic evolution of the Grand Canyon
You may have seen Ron Blakely's excellent paleogeographic maps of the North American continent. Browsing around his site the other day, I found this nice sequential cartoon of the geologic steps it took to build up the rocks at the Grand Canyon.
My dad and my two brothers and I are going rafting down the Canyon this summer, and I'm looking forward to exploring the geology firsthand from the river level. My four previous trips to the Canyon have all started at the rim, then hiked down (sometimes to Plateau Point, sometimes to the river), and then back up in the same day. Staying at river level for over a week ought to be awesome.

There's a new geologic map of the Butte Creek/Kaibab Monocline area, just published by the Grand Canyon Association. It's a lovely map, and looks fairly water resistant, and includes river miles on it. If I were planning a Grand Canyon river trip, I would bring it along.
Thanks for the tip -- I'll pick up a copy! -C.
As a graduate student of NAU, I am honored to be here during Ron's last year. He is an amazing geologist and knows the stratigraphy of the western US like the back of his hand!
