Kearsarge Pass
Peak · 11,709 ft · Eastern Sierra corridor
Kearsarge Pass is a 11709-foot alpine summit in California's Eastern Sierra. Wind-exposed and snow-dependent, it sits above Kearsarge Lake and draws peak-baggers and backpackers on stable weather windows.
Wind dominates the pass itself; the 30-day average is 13 mph, with gusts to 37 mph common in afternoons. Mornings are calmer. Snow coverage persists into early summer; avalanche terrain requires deliberate route choice and stable snowpack assessment.
Over the past 30 days, Kearsarge Pass averaged a NoGo Score of 37, ranging from 9 to 65; the 30-day average wind was 13 mph and average temperature 23 F. The week ahead will reflect typical late-April instability: watch for rapid afternoon wind rise and variable snow conditions on upper slopes.

About Kearsarge Pass
Kearsarge Pass sits at 11709 feet in the Eastern Sierra, straddling the crest between Inyo and Tulare counties. Access is via the Kearsarge Pass Trail, which departs from the Onion Valley Road near Independence, California. Independence sits on US Highway 395, roughly 175 miles north of Bakersfield and 130 miles south of Reno. The trailhead parking at Onion Valley fills by mid-morning on weekends and holiday weeks; arrive before dawn or plan a weekday trip to secure a spot. The pass itself is the logical high-point of a multi-day backpack loop; many visitors approach it as a leg of the Kearsarge Lakes circuit or use it as the pass on a Sierra crest traverse.
Spring and early summer bring unstable snowpack and avalanche hazard to Kearsarge Pass; the 30-day average temperature of 23 F and rolling maximum wind of 37 mph create hostile conditions for exposure. Late September and October offer the most stable conditions: snow has consolidated or melted, wind remains moderate, and crowds are lowest. Winter is avalanche terrain and requires expert snow assessment; the pass and surrounding slopes hold slabs. Summer (July through mid-September) brings lighter snow, lower avalanche risk, and warmer afternoons, but afternoon thunderstorms are frequent and the pass itself sees wind-driven whiteout conditions on exposed ridges. Crowding remains low year-round (average 2.0 on the rolling 30-day metric), a reflection of the remote access and multi-day commitment required.
Kearsarge Pass suits experienced hikers and backpackers with solid navigation skills and avalanche awareness. Day-hikers typically turn back at the pass itself; the summit is a minor bump beyond and not a prime destination in its own right. The appeal is the traverse itself, the alpine lake views, and the high-country solitude. Winter approaches demand ice axe, crampons, and current avalanche forecasts from the Eastern Sierra Avalanche Center (ESAC). Spring visitors should check snowpack stability and route condition reports before committing; north-facing slopes above the pass hold snow and slide debris well into June. Summer climbers should start early to avoid afternoon winds and electrical storms; the exposed pass offers no shelter.
Nearby alternatives include Kearsarge Lakes (lower, less exposed, reachable as a day-hike or overnight), and the higher crest peaks accessed from the Kearsarge Pass Trail or from the Onion Valley basin. Shepherd Pass to the north and Sawmill Pass to the south offer comparable alpine crossings with similar crowding and wind patterns. Visitors planning a Sierra crest loop often link Kearsarge Pass with Forester Pass or Shepherd Pass to the north; the routing depends on snowpack and personal tolerance for avalanche terrain. Independence and the surrounding Inyo National Forest offer lower-elevation alternatives (fishing, desert heat, less snow) if Kearsarge conditions are marginal.
