Keyes Peak Pass
Peak · 10,169 ft · Yosemite corridor
Keyes Peak Pass sits at 10,169 feet in the Yosemite corridor of California's Sierra Nevada. A high alpine crossing exposed to funneled wind patterns, it offers solitude and serious terrain for winter and shoulder-season travel.
Wind accelerates through the pass in afternoon hours, especially when pressure systems move in from the northwest. Morning conditions are typically calmer. Snow coverage persists into late spring; avalanche terrain demands careful route selection and snowpack assessment.
Over the past 30 days, Keyes Peak Pass averaged 11 mph wind and 25 degrees Fahrenheit, with a NoGo Score averaging 33. Wind gusts have reached 30 mph, and conditions have swung from a low of 6 to a high of 50 on the NoGo Scale. The week ahead reflects typical late-spring variability at this elevation; morning and evening windows remain your best chance for stable conditions and lower wind.

About Keyes Peak Pass
Keyes Peak Pass is a 10,169-foot alpine crossing in the Yosemite corridor of the central Sierra Nevada. The pass sits on the eastern shoulder of the range, accessible primarily by multi-day ski traverse or mountaineering approach from the Yosemite backcountry. It is not a drive-to destination; access requires either foot or ski travel from Highway 120 (Tioga Pass) vicinity or from the eastern Sierra trailheads near Lee Vining. Base popularity is low; most visitors who reach it are experienced mountaineers or backcountry skiers with avalanche training. The SAC (Sierra Avalanche Center) provides regional stability forecasts; always check current bulletins before committing to terrain near the pass.
Keyes Peak Pass sits in a zone where winter lingers well into spring. The 30-day average temperature is 25 degrees Fahrenheit, with rolling 365-day minimums as low as 14 degrees. Wind is the defining hazard here. The 30-day average wind is 11 mph, but gusts regularly exceed 30 mph as flow accelerates through the constricted terrain. Afternoon and evening hours see the strongest winds; morning departures yield the calmest windows. Crowding averages 3 (very low), meaning you will encounter few other parties. Late spring and early summer offer the shortest snow-free window; late September into October provides stable weather and lower avalanche hazard, though cold returns quickly at this elevation.
Keyes Peak Pass suits mountaineers, ski mountaineers, and backcountry skiers with solid winter navigation and avalanche education. The approach demands fitness, technical rock scramble capability, and self-rescue competence. Winter and early spring travel means careful assessment of slab stability on steep north and east-facing slopes; the presence of avalanche terrain demands conservative decision-making. Parties typically time passes for early morning or evening to avoid afternoon wind. Exposure to wind at 10,169 feet means layering for cold and wind chill that can drop perceived temperature well below the ambient 25-degree average. Water sources are minimal; carry sufficient reserves. Cell reception is unreliable; file a trip plan.
Keyes Peak Pass is rarely paired with other destinations in a single trip due to its remote access and specialized terrain. Nearby peaks in the Yosemite corridor (Matterhorn Peak, North Peak) offer similar alpine exposure and are accessed by comparable routes from Highway 120. The eastern Sierra access from Lee Vining provides alternative approaches to high passes and peaks in the Dana Plateau region. For visitors already committed to Yosemite backcountry travel, Keyes Peak Pass represents an advanced extension into genuine alpine terrain; it rewards careful planning and respect for avalanche hazard.
