Before heading in on the rugged 4WD track, we stopped and chatted with the volunteers who dry camp. Dry camping is often the only option out here. They pull a water tank, have a tank for sewage that is hauled out, and generate electricity using a windmill and solar panels.
The petroglyphs we looked at were small, faint, and overshadowed by graffiti from the the 1920’s. They were etched into the desert varnish, which is a black oxidized overcoat on the rocks. The effect of the drawing is the same as that elementary school project where you draw on a piece of paper, then color it with black crayon and etch through.
In a narrow wash a small series of rock pools contained rainwater. The shallowest pools were like tidepools, filled with tadpools. The larger ones were deeper than our hiking sticks. They contain a colony of endangered frogs that are being bred for a location in northern Arizona, though we only saw one as they blend into the environment and are the size of a thumbnail.
