So, apparently some ppl think mammoths used to rub against boulders and left them polished, particularly on overhanging rocks. The mushroom boulder in hueco comes to mind.

"Megafauna polish"

Im pretty skeptical, I always assume the polish is actually more like a desert varnish. The senior CA state archaeologist, breck parkman, however seems to give the idea credence:

Thoughts, supertopians? I know, I should stop thinking and just climb the frikkin stuff

I've heard this before and it seems pretty plausible. When you go to the sunset boulders at goat rock state park check out the most jagged sections of rock anywhere fro 5-15 feet off the ground they are way polished. Like the sharp point on the skull cracker and specialist or right on the arete of the pelican arete. Pretty cool!
