The first ascent was made on July 25, 1903 by James S. Hutchinson, Joseph Nisbet LeConte and James K. Moffitt. They approached the area overland from south of the Palisades, and scouted possible routes from the summits of Marion Peak and Mount Sill. Armed with this intelligence, they planned to ascend the southwest chute of the U Notch, and find a way to bypass the rock face between the notch and the upper reaches of North Palisade. Around , they followed a northward branch of this chute, and slowly climbed a difficult system of cracks. From here they found a catwalk ledge that took them to a series of icy gullies, bound toward the summit. These gullies were blocked by a pair of chockstones, requiring class 4 moves to pass. Beyond these obstacles, they crested the southeast ridge, and climbed a series of granite blocks to the summit.
