루트들 스포츠 클라이밍로서 驼背山 Humpback Mountain에서

From the top of Grandfathered In P3, climb up a short P4 to a small ledge. Then continue straight up and through the overhanging nose with an anchor at the very tip of the prow above you. The route then continues up to join with Grandfathered In at the P5/P6 belay. This pitch is the reason why Grandfathered IN was developed. Overhung, slab, and weird beta... good route.

From the top of Grandfathered In P4, traverse left out along the edge of the nose to finish at the belay near the tip. (same belay as for Old School). continue straight up to join grandfathered In.

VERY IMPORTANT! Descent : Do not abseil the top two pitches of this route ! While facing the anchor and with your back toward the climbing: throw your rope at the 4:00 O'clock angle and abseil 22m to a hanging belay nestled on some white rock. continue straight downt he wall for 2 more abseils arriving at the anchor above P4.
