Daff Dome, South Face, the Crescent Arch. This new climb was done June 2 by Layton Kor and me. The route follows a great right-curving arch in mid-face, very prominent from the nearby Tioga Road. The first two leads were primarily difficult fifth class, and the next two leads involved nailing under the curve of the arch, with a hanging belay en route. The final exit, led beautifully by Layton, was both wet and difficult. Easy slabs then led to the top. About 45 pitons were used.
