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.
This off-kilter riverblock with huge slopers features an exciting footless sequence but soft stone. Start in jugs at chest height. Might have a hard low start if only the rock quality was better.
