Because it's so flaky. Clip the bolt under the roof but step out and left to climb the large gong flake. Continue up the left side of the arete on flake jugs while clipping bolts on the right side of the arete (where the rock was better). As the flakes disappear, step around the arete onto the right face and continue up on small holds. The defined crux arrives after clipping two more bolts. After the short crux, finish on fun tricky slab bulges to the anchors. Possible pull through the crux on draws.The grade for this climb is height dependent 5.11a for those of us with shorter wingspan and, 5.10a for the rest.
