The area has two approaches from the road. The up canyon approach is described on MP and the down canyon approach is described in the new Leavenworth bouldering guide. Both are steep and are experiencing significant erosion. Were I to close one, I would choose the approach listed on MP. It is longer, and does not access boulders other than Tinman. The guidebook approach has the advantage of providing access to the Pen15 boulders and their descent. Photos are of the MP approach.
