The Desert View Watchtower Petroglyphs is a site in Grand Canyon National Park near Flagstaff, Arizona that we haven't visited yet. We have actually visited it but we don't have any photos of the petroglyphs. The petroglyphs are on rocks that were used in the construction of some of the buildings of the site. For turn-by-turn directions enter 'Desert View Watchtower' into your driving app.
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.
