Start from Moraine Lake. Get on the Larch Valley/Sentinel Pass Trail that starts just past the canoe docks on the north side of the lake. Follow the great trail all the way up to Sentinel Pass (2-3 hours) From the pass hike right up the ridge, maybe slightly on the right side of it. Follow a faint, crumbly trail up the 1st gully to the right of the ridge. Follow it to the top, when the gully hits a steep wall. Hike below the wall to the right into short gully. Go up this onto a scree slope. Keep going up, going past another wall to the right. Either climb right up onto the ridge or stay slightly below it on the right and continue going up and finally onto a sloping ridge crest. Follow this up and onto the summit.
