Some boulders and cliffbands are used by the park to demonstrate primitive shelters, not just for climbing, therefore reduced chalk use is highly recommended. Do not slap chalk onto the rock. Being good stewards and maintaining a healthy relationship with other users and with the park rangers should be a high priority for any visiting climber.
One move, a big right hook, is all it takes for this one. Start low on opposing sidepulls, an incut right hand and the lower of two left hand sidepull crimps. Slam a big move to a flat jug and top out. Often completely soaked.
