We got the location of 7 petroglyph sites in the Palo Verde Hills near Wintersburg, Arizona from Petry’s Rock Art of Arizona. There is a lot of private land in the area so without being there yet it is hard to tell which sites are accessible and which aren’t. We plotted likely routes on the map and created GPS tracks for each site that should give a good chance of success. As you can see from the map, several of the sites appear to be on BLM land.
To get there you can enter ‘Wintersburg, AZ’ into your driving app and then use the map and GPS tracks from there.
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.
