The Dzrtgrls and I headed out to the Mojave desert a few years ago to find a petroglyph and pictograph site. We were not disappointed. This is a large petroglyph site and required a few miles of hiking. It has thousands of petroglyphs and covers a few square miles of area in a lonely corner of Mojave National Preserve.
Most of the petroglyphs are likely of Chemehuevi, Mohave, and/or Archaic origin. If you venture out here, please respect this site. It is an amazing place.

We even found an arch! You can read the Dzrtgrls trip report here.
