Big Wall Petroglyphs
In late 2017, my friend JP and I explored the backcountry of Joshua Tree National Park. On our way to another site, we stopped at a small petroglyph site in a wash that we are calling the "Big Wall Petroglyphs."
Guy has explored the deserts and mountains of the Western US for over three decades. In that time, he has found a couple of hidden and remote locations that don't see many visitors. The best way to contact him is on this site.
