From the Tall Boy Boulder, head up the hill and to the right of the Stowed Boulder. Continue walking up and right, past a large boulder with a fun looking arete. Once past this large boulder, another large boulder will be visible just up the hill. This large boulder has two large cracks found on the downhill face. One of them is shaped exactly like Harry Potter's lightning bolt scar. Walk to the right of this face and up the hill, just a few more yards and the Ridgeback Boulder is found on the right.
