This Petroglyph is from the Painted Desert in Arizona. The Petrified Forest National Park is at mile marker 311 on interstate 40 about 22 miles west of Chambers,Arizona. The Painted Desert is part of this park. The park road is 29 miles long with turn-outs that have great views with fantastic colors. When I was there, there was free camping at the end of the road where it meets highway 15. Post # 16 on ABC Wednesday.
