P 13,680+, Mount Sill, Mount Mendel and Other climbs, 1990. In June, 1990, Ken Kenega and I climbed a dihedral on P 13,680+ for seven pitches on the right of the Rowell route (III, 5.10a). In July, Kevin Malone and I did a direct finish of Mount Sill’s east face. Where the Roper guide says that at one point there are two choices, we went in between. Three of the last five pitches were 5.9. In September, Kenega and I did a route on the north face of Mount Mendel on the rock rib right of the Mendel Couloir (III, 5.8). It was very loose and we wandered a lot.
