The U Notch
Peak · 13,924 ft · Eastern Sierra corridor
The U Notch is a 13,924-foot peak in the Eastern Sierra, straddling exposed high-altitude terrain with avalanche exposure. Harsh wind and cold dominate; plan accordingly.
Wind channeling through the notch reaches 46 mph on bad days and averages 12 mph over 30 days. Exposure is relentless; afternoon gusts are the rule. Morning calm is rare and brief. Snowpack instability governs winter approach safety.
Over the last 30 days, The U Notch averaged a NoGo Score of 36.0 with winds at 12.0 mph and temperatures around 19.0 degrees Fahrenheit. Scores have ranged from 4.0 (rare good windows) to 65.0 (severe conditions). Watch the week ahead for shifts in wind direction and any warming trend that could trigger slides in steep terrain.

About The U Notch
The U Notch sits on the crest of the Eastern Sierra at 13,924 feet, marking the boundary between drainages in one of California's most exposed alpine zones. Access requires approach from the west via Highway 395 through Lone Pine or from the north via Highway 120 into the high country. The location commands views across the Sierra crest and drops steeply on both flanks. Most parties reach it as part of a ridge traverse or as a technical climbing objective. The notch itself is a narrow saddle with little shelter; weather hits from all quarters.
Winter and spring bring deep snowpack and avalanche danger; the 30-day average temperature of 19.0 degrees Fahrenheit reflects sustained cold that persists through April. Snowpack instability is the primary concern on approach; consult ESAC forecasts before any winter or spring ascent. Summer (July through August) sees the lowest wind averages in the annual cycle, though 12.0 mph rolling 30-day winds show it never truly calms. Fall can deliver rapid weather shifts. Crowding is minimal year-round; base popularity of 0.2 means this is a technical peak pursued by experienced parties, not a scenic destination.
The U Notch suits mountaineers and climbers comfortable with exposure, avalanche terrain, and sustained wind. A NoGo Score averaging 36.0 over 30 days signals poor conditions more often than not. Skip this peak if you need shelter or calm. Experienced parties go when the 30-day rolling trend shows a dip below 30, temperatures creep above freezing on stable days, and ESAC issues a favorable avalanche forecast. Afternoon wind acceleration is predictable; start before dawn if you go. Snowpack assessment is non-negotiable in winter and spring.
The U Notch pairs with nearby technical peaks on the crest as part of longer traverses. Lone Pine Lake and the surrounding drainages offer lower-elevation alternatives when high-altitude conditions are unsafe. Sierra climbers often bracket a U Notch attempt with acclimatization days at base camps around 11,000 to 12,000 feet. The Eastern Sierra corridor's weather is driven by storm systems crossing the Great Basin; high pressure from the northeast typically delivers the calmest windows. Plan for multi-day trips that account for weather delays.
