The Hand Of?

I was in the Sierra Nevada Mtns of California last weekend at about 7000 ft near Utica Reservior. This is an area that was well glaciated 10,000 years ago. Driving down the road, I noticed this formation of rock. What struck me about it was it seems to be assembled as one might build a rock wall: albeit at a rather large scale. Not sure how this came about that the rock got fractured but each joint was rounded smooth. I pretty much left it as shot. I thought about cloning out the ULC and LRC but decided that it probably wouldn't look right. Cropping would have eliminated some important features. So it got left as is. Comments and critiques welcomed.
