OK, OK, I remember Pumpelly via his eponymous mineral, but please tell me (I'd like to say "remind me" but I'm not sure that would be accurate)what the .... his rule was.
Callan, amazing diversity of rocks in the photo, where you are crouching down, a waterfall behind your head, rock formations to your side that look like an old man-made wall, And the curved stromatalites - the angle was changed on them after they were deposited?
A calcified bat?? They must be able to hold on after they die? Since they sleep upside down it can't take up too much energy.
Many great pictures on your blog for a geology enthusiast to enjoy!!

Thomas,
Stromatolites are deposited in curvy shapes -- that's what makes them distinctive.
I think the bat died and it's little toenails kept it pinned to the rock just under the influence of gravity.

I was being lazy and didn't look up stromatolites - figured it was something similar to stalaGmites (ground based) and stalaCtites (ceiling based). That is my personal memory trick.
So those stromatolites were living depositions of some type of bacteria - today mostly Cyanobacteria is left to produce these.
The layers you are looking at are very ancient, from the time when oceans or seas covered that part of the US?
Or alternately, Yellowstone springs today feed some exotic heat-loving bacteria depositions in some wild looking ponds. No ... the Helena Formation, Glacier National Park isn't Yellowstone.
So what gives you the right to go scampering over millions of years of God's creation doing a smash and grab of all these wonderful rocks? (kidding Callan - it just sounded funny.)
I oughta go find a job!
best to ya,
tom donlon
P.S.
Maybe I should get away from this computer before I get stuck here. See what happened to the bat - it may have figured it would just sleep in for a day.
