Cube Point, Southwest Apex. Barry Corbet and Chuck Satterfield on September 4, 1966, climbed this new II, F8, A2 route on the familiar Cube Point. From the main Symmetry Couloir the base of the climb was reached via the subsidiary couloir leading to the notch separating Symmetry from Cube Point; the route starts some 500 feet below the notch and to the right (east) of the smooth southwest face. The climb began by scrambling up and right toward a tree on a slanting apron of rock. The first lead from the far side of the ridge started with a 50-foot open-book. After jogging left, they moved back into the continuation of the open-book, ending with another move left and up over a difficult 10-foot F8 bulge to an out-sloping belay ledge. The second pitch zig-zags up the ridge past a section of slightly loose rock to a belay position below a dark overhang. Starting from a point 10 feet left of the belay point they climbed the crux pitch up a series of difficult slabs to a bulge which was passed using two pitons for aid. A 20-foot tight chimney then led to a ramp which was followed back to the nose of the ridge, where a delicate free climb up the nose itself took them to the next belay stance. One hundred feet of F3 climbing ended at the base of a 30-foot smooth face which was climbed with difficulty. A final easy lead took the party to the false summit, from which it was but a scramble to the main summit.
