The Inscription Rock Petroglyphs is a site in Bullhead City, Arizona that we haven't visited yet. The site is located just below Davis Dam, on the Colorado River, in the Davis Camp Park. For turn-by-turn directions you can enter 'Davis Camp Park' into your driving app. It will direct you north on AZ-68 from Bullhead City to McCormick Blvd. where you will turn left. After paying the entrance fee you will proceed to Arizona Street, go right, and just after crossing a wash you can park on the right. I believe the petroglyphs are within a fenced off area and that a telephoto lens will be required for good pictures.
Included with this post is the GPS file and map that we plan to use for our first visit. If you don't want to wait for us to get around to it feel free to try the GPS file and map for yourself. With no guarantee, of course, but they most often prove valuable for us.
