This small, unique boulder sits inches away from Flagstaff Road and you've likely driven, biked, ran, or pogo-ed past it numerous times. You may have noticed the four drill holes located on the side of the boulder facing the road. Road Sign Rock (and a few nearby boulders) host a few interesting problems, the most popular being the Northwest Overhang (B1).
Getting There
Park in the same dirt pullout as for the Capstain boulder or Cloud Shadow area. Get out of your auto and walk uphill past the Capstain, which will be on your right, then look across the road at the rock with four drill holes - that's Road Sign Rock.
