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....
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
