The Harcuvar Boulder Petroglyphs is a site near Harcuvar, Arizona that we haven't visited yet. The boulder is in a fenced off area along US-60 between mile markers 52 and 53.
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.
