Pegleg Mountain
Peak · 7,099 ft · North Sierra corridor
Pegleg Mountain rises to 7,099 feet in California's North Sierra, a granite peak exposed to persistent afternoon wind and accessible year-round via Highway 89. Conditions here are colder and windier than lower lake basins.
Wind dominates Pegleg Mountain's character. Afternoon thermals push gusts across the exposed ridgeline by mid-day; mornings are calmer but brief. Temperatures run 10 to 15 degrees colder than valley floors. Snow lingers into late spring. Check avalanche terrain awareness before winter approaches.
Over the last 30 days, Pegleg Mountain has averaged a NoGo Score of 35.0, with wind holding steady near 10 mph and temperatures around 36°F. Crowding remains light at 5.0 on the scale. The week ahead should hold similar conditions, though watch for afternoon wind spikes as seasonal heating intensifies. Winter snowpack is the dominant variable; spring transitions can shift avalanche risk rapidly.

About Pegleg Mountain
Pegleg Mountain sits in the North Sierra corridor, east of Lake Tahoe's rim and north of Highway 120. The peak is reached via Highway 89, which forms the primary access spine for the region. Nearest trailheads and services cluster around Tahoe City (west) and Susanville (east). The peak's granite summit and flanking ridges offer scrambling and ski touring routes that vary sharply by season and snow stability. Elevation and exposure make this a serious destination; casual hikers should confirm route and snowpack conditions before committing.
Pegleg Mountain experiences a hard seasonal split. Winter brings deep snow, avalanche terrain risk, and road closures on Highway 89 during heavy storms. Spring thaw (March through May) creates wet-slab instability on north-facing slopes; crowding remains minimal because access is still uncertain. The 30-day average temperature of 36°F reflects late-spring conditions; expect sustained cold until mid-May. Summer (June through August) trades snow for afternoon wind; the 30-day rolling average wind of 10 mph understates afternoon gusts, which regularly exceed 15 mph by 3 pm. Fall quiets wind and temperature, making September and early October the most stable window.
Pegleg Mountain suits experienced alpinists, ski mountaineers, and winter climbers willing to evaluate avalanche risk and commit to early starts. Summer hikers and scramblers should plan for morning ascents to avoid afternoon wind exposure on the ridgeline. Parking is minimal at most trailheads; arrive before 8 am on weekends. Afternoon wind makes descents on loose terrain hazardous; the 30-day max wind of 23 mph reflects gusts strong enough to destabilize scrambling on exposed rock. Winter and spring visitors must consult the Sierra Avalanche Center forecasts and carry rescue gear. Smoke rarely penetrates this elevation in summer, but visibility can degrade after afternoon thermals develop.
Nearby peaks in the North Sierra corridor like Sierra Buttes and Castle Peak offer lower-elevation alternatives with shorter approaches and reduced avalanche terrain. Mount Lassen, though farther north, sits at similar elevation but receives more stable winter snow. Pegleg Mountain distinguishes itself by its direct exposure to afternoon wind and its avalanche-prone north faces, making it best suited for visitors with mountaineering experience and early-morning discipline.
