Mule Pass
Peak · 10,478 ft · Yosemite corridor
Mule Pass is a 10478-foot Sierra Nevada peak in the Yosemite corridor, exposed to afternoon wind but rewarding for winter and early-season backcountry travel when snow and avalanche conditions permit.
Wind accelerates up-valley in the afternoon, driven by thermal circulation off the high basins. Mornings offer relative calm before gusts build by mid-day. Cold at elevation persists through spring; expect sustained winds averaging 15 mph with gusts to 42 mph during unstable pressure systems.
Over the last 30 days, Mule Pass averaged a NoGo Score of 34.0 with temperatures holding at 21 degrees Fahrenheit and average wind of 15 mph. The week ahead should track similarly unless a high-pressure ridge anchors offshore. Watch for spikes in afternoon wind and monitor avalanche advisories closely; snowpack on terrain above 10000 feet remains reactive through late spring.

About Mule Pass
Mule Pass sits at 10478 feet in the high Sierra crest of the Yosemite corridor, straddling the drainage divide between the Sierra's eastern and western slopes. Access is via backpacking routes that climb from the Eastern Sierra or from Highway 120 approach points in the Yosemite high country. The peak is not a roadside destination; reach requires a multi-day effort through alpine terrain. Base popularity remains low (0.2), meaning few crowds but also minimal maintained infrastructure. Winter and spring ascents demand avalanche awareness and route-finding skill; the SAC Avalanche Forecast Zone covers this area.
Conditions at this elevation run harsh and changeable. The 30-day average temperature of 21 degrees Fahrenheit reflects late-winter and early-spring reality; the rolling 365-day minimum of 7 degrees marks the coldest spells. Wind is the dominant factor. Average wind speed over 30 days runs 15 mph, with recorded maxima of 42 mph on unstable days. Afternoon winds funnel off the lakes and basins to the east; morning windows offer the calmest conditions for travel or bivouac. Crowding averages 3.0, meaning sparse usage but no guarantee of solitude on good-weather weekends.
Mule Pass suits experienced alpine and backcountry skiers, mountaineers, and climbers who factor avalanche terrain and multi-day logistics into their planning. Spring ascents coincide with corn-snow windows if snowpack has adequately bonded; early summer offers rock and scree once the pass clears. Expect no water sources at the pass itself; plan water strategy from valley camps. Parking and trailhead access depend on which approach you choose; confirm road status on Highway 120 before committing, as Sierra passes remain intermittently closed through late spring. NoGo Score of 34.0 over 30 days indicates frequent marginal or poor conditions; trip success hinges on reading the 7-day and hourly forecast rather than assuming a visit date will work.
Nearby peaks in the Yosemite corridor (including peaks along the crest and those approached via High Sierra Camps) offer similar elevation and exposure but may have slightly better trailhead access or lower avalanche terrain complexity. Mono Basin and Eastern Sierra entries provide alternative access to the crest; Highway 395 corridors (Lee Vining, Mammoth) sit 2 to 3 hours' drive east. For travelers seeking high-alpine experience with lower avalanche commitment, ridgelines in the Cathedral Range or Lyell Group offer comparable views with faster approach times.
