The Robbers Roost Canyon Petroglyphs are in the Tonto National Forest east of New River, Arizona. To get there take I-17 Exit 236 and go east on the W Table Mesa Road (99034). Once the road crosses into the Tonto National Forest it becomes FR 41. About 10.5 miles from I-17 the road reaches Robbers Roost Canyon which drains off to the south. The petroglyphs are reported to be around the mouth of the canyon. Which side of the road we aren’t sure.
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.
