Sometimes rocks just, well, rock! From small stones to huge boulders, they are the raw materials of the planet, and can be strikingly beautiful. Rocks are, of course, not unique to the Great Plains, but sometimes in an open landscape, they can stand out and assert their presence, reminding us that while we and our civilizations come and go, some things will remain unmoved and unchanged.
I find this comforting, and yes, I like rock music too!
