Unicorn Peak
Peak · 10,823 ft · Yosemite corridor
Unicorn Peak (10,823 ft) sits in the high Sierra above the Yosemite corridor. A steep alpine summit with avalanche terrain and exposed ridges; typically windier than sheltered valley floors.
Wind accelerates in the afternoon as thermals warm the exposed ridge. Expect 12 mph average conditions with gusts to 33 mph by mid-day. Morning approach windows close quickly; afternoon descents meet stronger wind and visibility loss from cloud build.
The 30-day average wind of 12 mph and temperature of 24 F mark typical spring conditions on the high crest. The next 7 days continue this pattern with afternoon wind intensification. Check avalanche stability before any approach; snowpack sits unstable through April.

About Unicorn Peak
Unicorn Peak (10,823 ft) crowns the high divide east of Tenaya Lake in Yosemite's Sierra Nevada spine. Access via Highway 120 to the Tuolumne Meadows corridor, then cross-country or scramble routes from the south. The peak sits above active glacial drainages and sits exposed to the jet stream; no marked trail reaches the summit. Winter and spring approach requires full avalanche terrain competency; the slope above the lake basin sits in high-hazard terrain.
Spring conditions on Unicorn Peak are raw. The 30-day average temperature of 24 F paired with 12 mph wind creates wind-chill below zero at exposed ridges. Afternoon wind accelerates as thermals develop; the 30-day maximum wind reached 33 mph. Snow remains deep and unstable through April; wet-slab avalanche risk peaks in afternoon hours when sun-crust collapse triggers larger slides. By late May, snow line drops below 10,000 ft and approach becomes scramble-focused. Summer sees calmer wind (averaging below 10 mph) but afternoon thunderstorms develop daily by late July. Crowding stays minimal; the 30-day average of 3.0 (scale 1-10) reflects poor road access in winter and spring, and the peak's scramble-only character.
Unicorn Peak suits experienced mountaineers and skiers with avalanche training. Weekend crowds on Highway 120 cluster near Tenaya Lake and Tuolumne Meadows; few venture to the peak itself. Spring ascents demand predawn starts to beat afternoon wind and cloud. Descents after 2 pm face accelerating ridge wind and reduced visibility. Parties planning ski or snowboard descent must assess slab stability at 8 am; afternoon re-ascent is impractical. Summer scramble parties should start by dawn to clear ridges before 3 pm wind.
