Scrambling up some really, really big slabs of Quartz Monzonite (an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars), I spotted a bedrock mortar. (One main thing to remember about Quartz Monzonite: if you slide down it on your rear end, you are going to tear your pants.)

A little more climbing and I was there. I've called this location the Piano Valley Pictograph Site, simply because I walked through Piano Valley on my way to it. It's a nice spot with a great view and was a pleasant place to take a rest after taking some pictures of the faded pictographs.
