Follow the Sunset Glacier to its upper basin and take the shorter southwesterly fork (watch for crevasses) to the small col below the peak's south ridge. From here, climb a steep snow slope to the north and cross a small basin to the east (beware of big cracks later in the summer). Gain the southeast ridge by climbing a short headwall (the routes crux). The slope here rolls to anywhere from 40-55 degrees (some may want to pitch out this short section because of a large bergschrund). Once on the ridge, go uphill to the summit, beware of cornices to the northeast and avalanche danger to the south. The route is essentially a corkscrew up the mountain.
Basic glacier travel set up (piolet, crampons, pickets, etc...).
