I mean that I meant to post this in the O'club.
My uneducated guess is that it is stratified sandstone which is a freshwater sedimentary rock. Which means it was once the bottom of a big lake. I really don't know. I was hoping somebody here had some geology to teach us.
You'd need at least a rock hammer and preferably a petrographic microscope to elucidate that sort of information. The surfaces of the rock that you can see are too eroded (not to mention too far away) to really get a good idea of what it's made out of. Erosion has an unfortunate tendency to make everything look the same, especially wind erosion. The best you could do in a situation like this is that it looks like it was uprooted and dropped from a glacier, and that they're probably sedimentary / weakly metamorphosed. Identifying rocks in the field (i.e. no petrographic microscope) comes down to biting them sometimes, it's a pretty tactile process.
t. technically i study geology
Yep, dropped via an ice sheet as the earth warmed up.
Side note, in the history of the earth 90% of the time it is too hot for polar caps. This means we currently live in the 10% of history, where it is cold enough. Al gore.... ![that feels better :bhead](http://bbs.hitechcreations.com/smf/Smileys/default/bangheadz.gif)
boo
it's also only in the past 10,000 years of 200,000 years of biologically modern humans that the climate has been stable and favorable enough to support human civilization
