This is a small petroglyph site in the Mojave desert: a couple dozen glyphs on an eroded lava flow above a wash. Unfortunately, vandals have found the site too and scratched some spindly marks around or over some of the petroglyphs.
We visited this petroglyph site in mid-spring, on what turned out to be a pretty hot day. Instead of taking the Rings Loop trail, we parked in a different spot and approached the petroglyphs from the other side. This lead to a bit of consternation on my part, since the petroglyphs are all on the far side of the boulders, except for one very small panel, and I thought that we drove all the way out here for a couple of petroglyphs and I would have to apologize to my companion for creating such a journey for the sake of two petroglyphs!
