You're on the second, south-facing face, from the west, on Tuck (confusing, perhaps); just west of a clean, curving dihedral with a tiny crack running the length of it. There are so many options here...the stated route is climbing the arete that is formed on the left edge. However, there's a fun and tricky move moving onto the ledge about 10 feet off the ground on the left side. From there, move up underclings, grab and mantle another huge and solid ledge. Follow up and right to an easier finish.
