Climbing the East Ridge from Milestone Basin
From Independence on US 395, drive Onion Valley Road west, turn south on Foothill Road and follow signs to the Symmes Creek trailhead. The Shepherd Pass Trail climbs over a saddle into Shepherd Creek and on to the pass, then you descend Tyndall Creek and take the Lake South America trail into the upper Kern basin. Head west up Milestone Creek into Milestone Basin and climb the East Ridge, finishing on the Class 3 summit pillar. The trip is long, high and remote, and the pass can hold snow into July. Plan four days. An Inyo National Forest wilderness permit is required; reserve months ahead.
