Summit Pass
Peak · 10,250 ft · Yosemite corridor
Summit Pass, a 10,250-foot peak in the Yosemite corridor, marks a high Sierra crossing exposed to sustained wind and snow. Winter and spring access is weather-dependent and requires avalanche awareness.
Wind dominates here. The 30-day average runs 15 mph with gusts to 33 mph; afternoon flows are reliably stronger than morning. Temperature averages 25 degrees Fahrenheit. Exposure and elevation mean conditions deteriorate fast once weather moves in. Early departure is mandatory.
Over the last 30 days, Summit Pass has averaged a NoGo Score of 33 with wind averaging 15 mph and temperature at 25 degrees Fahrenheit. The week ahead shows typical late-spring variability; afternoon wind intensification is the rule. Check avalanche and weather forecasts daily; snow stability and wind-loaded slopes remain the primary constraint through May.

About Summit Pass
Summit Pass sits at 10,250 feet on the high Sierra crest within the Yosemite corridor, straddling the main route across the range between the Central Valley and the eastern Sierra. Access from the west via Highway 120 through Tioga Pass is the standard approach; the drive from Lee Vining or Yosemite Valley is 2 to 3 hours depending on road conditions and season. Highway 120 closes seasonally; opening timing varies from late April to early June depending on snowpack and avalanche activity. The pass is a transit point for backcountry travel, mountaineers, and peak baggers; it is not a populated area or ski resort. Cell coverage is minimal to nonexistent.
Winter and early spring conditions are dominated by deep snow, avalanche terrain, and sustained wind. The 30-day rolling temperature averages 25 degrees Fahrenheit; the year-round temperature range spans 10 to 40 degrees. Wind is relentless, averaging 15 mph with documented gusts to 33 mph; afternoon flows accelerate predictably. The rolling 30-day NoGo Score averages 33, indicating challenging conditions are the norm, not the exception. Crowding is minimal at 3 on the rolling 30-day scale, reflecting both the difficulty and the low base popularity of this high-elevation pass. Late spring brings marginal improvements in temperature but not in wind or snow hazard.
This location is for experienced mountaineers and backcountry travelers with avalanche training and winter route-finding skills. Day trips and casual visits are not typical here; most use is expedition-based or part of a longer traverse. Parking is extremely limited; vehicles parked at the pass trailhead face wind damage and potential burial under drifting snow. Visitors must monitor the Sierra Avalanche Center forecasts and understand slope aspect, snowpack history, and wind-loading patterns. A descent in heavy afternoon wind on steep, loaded terrain is a genuine hazard. Bring shelter, water, and navigation tools. Do not rely on cell phone navigation or communication.
The Cathedral Range and the main crest peaks lie immediately north and south; Mount Dana (13,053 feet) is a nearby landmark. Lee Vining Canyon drains eastward from the pass toward Highway 395. Tioga Lake and Tenaya Lake sit to the west at lower elevation and are accessible year-round when Highway 120 is open. Mount Hoffmann and Tuolumne Meadows are further west and offer more sheltered alpine travel once the snow season breaks. Highway 395 on the east side of the crest offers faster access to lower-elevation destinations but does not shorten the approach to Summit Pass itself.
