Quarry Peak-South Peak
Peak · 10,846 ft · Yosemite corridor
Quarry Peak-South Peak is a 10,846-foot alpine summit in the Yosemite corridor of California's Sierra Nevada. Sitting at high elevation, it commands exposure to afternoon wind and requires winter route planning.
Wind accelerates upslope in the afternoon, typically sustained at 10 mph with gusts to 30 mph by mid-day. Morning windows close by mid-afternoon. Snow and ice persist through spring; assess stability before ascending exposed terrain.
Over the past 30 days, Quarry Peak-South Peak has averaged a NoGo Score of 32, with temperatures around 26 degrees Fahrenheit and average wind of 10 mph. The week ahead mirrors this pattern; wind will dominate the afternoon forecast. Check avalanche terrain stability through the SAC bulletin before committing to exposed slopes.

About Quarry Peak-South Peak
Quarry Peak-South Peak sits at 10,846 feet in the Yosemite corridor, accessible primarily from the Sierra Nevada crest approach via Highway 120 corridor gateways. The peak sits in avalanche terrain; consult the SAC avalanche center forecast before travel. Base popularity is low, meaning solitude is typical, but remoteness demands self-sufficiency. Winter and spring ascents require winter travel skills and current snowpack assessment. Summer access narrows to a short window after snowmelt and before early autumn storms.
The 30-day average temperature of 26 degrees Fahrenheit reflects alpine spring conditions; expect the minimum temperature range to reach 13 degrees Fahrenheit and maximum to 41 degrees Fahrenheit across the year. Wind is the dominant constraint: the 30-day average of 10 mph understates afternoon severity, with gusts regularly reaching 30 mph by mid-day. Crowding averages 3 on the 10-point scale, indicating light to minimal traffic. The area experiences pronounced diurnal wind cycles; calm mornings give way to sustained afternoon wind, making early starts non-negotiable.
This peak suits experienced mountaineers comfortable with avalanche terrain, winter travel, and self-rescue. Day trips from valley floors require pre-dawn starts and rapid descent before afternoon wind builds. Parties planning multi-day approaches should cache supplies and monitor the SAC bulletin continuously. Afternoon wind makes exposed traverses dangerous; descents before 14:00 are standard practice. Parking and trailhead access follow Highway 120 corridor protocols; arrive early or expect to backtrack to lower-elevation alternatives.
Nearby peaks in the Yosemite corridor offer lower-elevation alternatives when Quarry Peak-South Peak conditions deteriorate. The low base popularity of Quarry Peak-South Peak means fewer established trails and less trail maintenance; navigation skills are essential. Spring snowpack can linger longer than at more-visited peaks because foot traffic is sparse. Solo travel is common but carries higher consequence; abort plans if conditions or personal fitness do not align with the objective.
