The Boulder Creek Petroglyphs is a site near Phoenix, Arizona that we haven't visited yet. Take I-17 Exit 236 and follow the Table Mesa Road. After paralleling the interstate to the north a short distance go left onto the West Table Mesa Road. The total distance from the interstate is about 6.8 miles.
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.
