The South Fork Road Petroglyphs are located west of Eagar, Arizona. To get there, drive west on AZ-260 for 5.4 miles and turn left onto CR 4124. Continue for 1.45 miles where the petroglyphs will be on your right. The petroglyphs are visible from the road but it looks like there is a pullout on the opposite side of the road where you can park to get a closer look.
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.
