South Ridge of Drizzlepuss. On July 6, 1957 William Cropper and John Dietschy took ten hours to climb the sharp ridge from Leigh Canyon to the summit of Drizzlepuss, the well known pinnacle at the base of the east face of Mount Moran. They avoided the two great vertical steps, the first by a diagonal ledge on the east side of the crest, the second by a very curious, almost horizontal, crawl-space along its west side.
