The South Spur is the most popular and least technical route on the mountain. Mules made the ascent on a regular basis during the mining era. Hike South Climb Trail 183 to the left edge of the tiny Crescent Glacier and on to the "Lunch Counter," a flat area at about 9,000 feet. Ascend Suksdorf Ridge to the false summit (11,657'). Continue across a gentle saddle to the true summit.

The route is easy, with no special difficulty or danger, except possibly avalanches in early season. Although the route does cross the summit ice cap, if you stay on the route crevasses are not a problem. Bring crampons and ice axes. Glissading is the most popular method of descent, but should not be attempted when snow cover is insufficient to provide a safe run out. Some parties camp at the Lunch Counter, although the round trip is feasible from Cold Springs if you start early. This is a popular ski descent in early summer. (6-8 hours)
