The Indian Bread Rocks Petroglyphs is a site near Bowie, Arizona that we haven't visited yet. To get there enter 'Indian Bread Rocks Recreation Area' into your driving app for turn-by-turn directions. From Bowie it should direct you south on S Apache Pass Road for about 4 miles and then right onto Happy Camp Canyon Road for another 3 miles to a picnic area. The GPS coordinates are for the picnic area itself. I suppose that from there you would explore the various social trails to find any petroglyphs.
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.
