Chittenden Peak
Peak · 9,580 ft · Yosemite corridor
Chittenden Peak is a 9,580-foot summit in the Yosemite corridor of the high Sierra. It sits in steep, avalanche-prone terrain with dramatic exposure to afternoon wind.
Wind accelerates through the afternoon, funneling off the surrounding ridges and high lakes. Morning hours are calmer but brief. Temperatures stay well below freezing most of the year; expect rime ice and wind-slab conditions in winter and spring. Crowding is light year-round.
Over the last 30 days, the average wind speed has been 11 mph with peaks near 30 mph, and the average temperature has held at 25 degrees Fahrenheit. The next week will show how spring conditions evolve; monitor the wind trend closely if you're planning an alpine approach. Avalanche terrain here demands current snowpack assessment from the Shasta Avalanche Center.

About Chittenden Peak
Chittenden Peak rises at the northern edge of the Yosemite high country, roughly 50 miles northeast of Yosemite Valley via Highway 120 and the Tioga Pass corridor. The peak sits above a complex of lakes and glacially-carved basins at the head of the Lee Vining drainage. Access is primarily from the east side via the June Lake Loop or from the west via the Tioga Pass road and high-country trailheads. The nearest resupply is Lee Vining to the east or Tuolumne Meadows to the west. Approach routes cross significant avalanche terrain; late-season ascents (after mid-summer) avoid most slide risk, but spring and early-summer climbers must assess the snowpack daily with the Shasta Avalanche Center forecast.
This peak sits at the extreme high elevation of the Sierra crest and experiences the full force of westerly wind patterns that accelerate down the east slope. The 30-day average wind speed of 11 mph masks afternoon gusts that regularly exceed 25 mph by mid-day. Temperatures average 25 degrees Fahrenheit over the last month, with extremes ranging from 14 to 39 degrees Fahrenheit across the full year. Winter and spring (November through June) are characterized by deep snow, wind-loading on leeward aspects, and persistent above-freezing conditions only at lower elevations. Late summer and early fall offer the most stable snow-free or minimal-snow windows, though afternoon winds remain the dominant hazard. Crowding has averaged only 3 out of 10 historically, making this a genuinely quiet objective.
Chittenden Peak suits experienced alpinists and mountaineers comfortable with steep rock, exposed ridges, and self-rescue. Winter and spring ascents demand avalanche training and conservative decision-making; the exposed terrain and high wind speeds make this peak especially punishing for parties caught in storms or caught unprepared for rime ice. Most successful ascents happen in late summer and early fall when snow is minimal and morning windows before afternoon wind are most reliable. Parties should plan to start before dawn, summit by early afternoon, and descend before wind peaks. Parking near the trailhead can fill on weekends, but overall visitation remains low enough that solitude is the norm rather than the exception.
The nearby peaks of the Mono Basin and northern Sierra Nevada offer related objectives at similar elevations. Mount Dana (13,053 feet) lies southwest and is more accessible from the Tioga Pass road, though it also experiences severe afternoon wind. The volcanic peaks around Mono Lake to the east present lower-elevation alternatives with less avalanche terrain. For parties seeking a less technical, lower-elevation alternative in the Yosemite corridor, the Lyell Canyon approach and peaks above Tuolumne Meadows offer gentler terrain and better protection from wind. Chittenden Peak is best reserved for climbers with solid winter mountaineering experience and a clear weather forecast.
