The Hieroglyphic Point Petroglyphs is a site near Globe, Arizona that we haven't visited yet. The petroglyphs are located on a boulder at the Salt River Canyon Rest Stop about 39.5 miles from Globe on US-60 between mile markers 290 and 291. For turn-by-turn directions you can enter 'Salt River Canyon Rest Stop' into your driving app and pick the one that says San Carlos, AZ.
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.
