Bigelow Peak
Peak · 10,541 ft · Yosemite corridor
Bigelow Peak rises at 10541 feet in the Yosemite corridor of California's Sierra Nevada. A high alpine summit with avalanche terrain, it sits exposed to afternoon wind and seasonal snowpack instability.
Bigelow Peak channels wind off the high Sierra plateau; afternoon gusts accelerate as thermal heating intensifies. The 30-day average wind of 11 mph masks swings to 30 mph by mid-day. Approach at dawn to dodge the afternoon blow; expect avalanche hazard in winter and early spring when snowpack is consolidating.
Over the last month, Bigelow Peak averaged 33 on the NoGo Score with temperatures around 25 degrees Fahrenheit and average wind of 11 mph. The week ahead shows typical spring variability; afternoon wind picks up consistently. Watch for rapid snowpack change as temperatures fluctuate across the freezing threshold.

About Bigelow Peak
Bigelow Peak stands at 10541 feet in the Yosemite corridor, accessed via Highway 120 from the east or Highway 140 from the west. The peak sits in the high alpine zone above 10000 feet, surrounded by glacially-carved terrain and seasonal water drainages. Primary approach is from the Tioga Pass gateway (Highway 120), with Mammoth Lakes and Lee Vining as nearest services. The location sits north of the Cathedral Range, in terrain managed by the Sierra Nevada Conservancy and within the Inyo National Forest boundary. Winter access requires 4WD or chains; summer typically opens by late spring depending on Highway 120 snow conditions.
Bigelow Peak experiences winter as a genuine snow-loaded environment; the 365-day temperature minimum of 14 degrees Fahrenheit and seasonal snowpack create avalanche terrain that demands constant assessment. The rolling 30-day average of 25 degrees puts the peak in a zone where wet-slab and cornice-fall hazard remains active through spring consolidation. Wind is relentless at this elevation; the 30-day average of 11 mph reflects frequent gusts to 30 mph in afternoon hours. Crowding averages 3 on the rolling 30-day metric, meaning the peak draws a small, experienced user base rather than casual foot traffic. Spring and early summer see faster snowmelt and route instability; late September offers the best stability and mildest conditions.
Bigelow Peak suits climbers and mountaineers comfortable with steep scrambling, exposed ridges, and avalanche-terrain decision-making. Winter ascents demand ice-climbing skill and full winter mountaineering kit. Summer visitors navigate talus fields and residual snowpatches; the exposed elevation means weather window is narrow. Afternoon wind makes summit time critical; experienced parties start before dawn and summit by midday to avoid the gusts that build by afternoon. Parking is limited; the nearest highway pullouts fill early on weekends. Solitude is the primary draw; this is not a peak with maintained trails or hut infrastructure.
The Yosemite corridor offers alternatives at lower elevation with less avalanche exposure. Cathedral Peak (9776 ft) to the south is more accessible and has wider summer climbing windows. Mount Dana (13053 ft) to the east is higher but sits in exposed tundra with similar wind exposure. For those seeking high-Sierra peaks with less technical commitment, the Lyell Range offers Class 2 and 3 options lower in elevation and less prone to afternoon wind acceleration. Bigelow Peak remains a pure alpine destination; plan around snowpack stability, afternoon wind, and the compressed good-weather window at 10541 feet.
