Climbing

The north face of Notch Peak is divided by a large shelf into an upper and lower wall. There are several rock climbing routes on the limestone cliffs. "The Swiss Route" (never repeated), "Direct North West Ridge (AKA. Pillars of Faith), and "Book of Saturdays" ascend the upper wall. On the lower wall "Appetite for Destruction" and "Western Hardman" reach of vertical. Climbing on all of these routes is adventurous with rockfall hazard and loose flakes of widely varying size. In addition to the face of Notch Peak, the granite found in the canyon below the notch is also used for climbing.
