North Notch
Peak · 11,427 ft · Yosemite corridor
North Notch is an 11,427-foot peak in the Yosemite corridor of California's high Sierra. A technical summit with avalanche terrain, it demands winter caution and clear conditions.
North Notch funnels wind from the east; afternoon gusts commonly exceed the 12 mph rolling average. Exposure is severe above treeline. Morning stability erodes fast; by late morning, thermal updrafts and cross-valley flow make the ridge untenable for exposed travel.
The 30-day average wind of 12 mph masks afternoon peaks near 33 mph; temperature hovers around 22 degrees Fahrenheit. The week ahead will likely follow the same pattern: calm early hours, building wind and cloud by midday. Plan ascents for dawn and expect to retreat by 10 a.m.

About North Notch
North Notch sits at 11,427 feet in the high Sierra above the Yosemite corridor, accessed primarily via Highway 120 from the west or Highway 395 from the east. The peak rises above glacially-carved basins and sits adjacent to the Cathedral Range. Drive times from Yosemite Valley or Lee Vining average 90 to 120 minutes depending on approach. Winter road closures on Highway 120 typically isolate the peak from November through May; check CalTrans and Caltrain conditions before committing.
Winter and spring conditions dominate North Notch's character. The 30-day average temperature of 22 degrees Fahrenheit reflects persistent snowpack; the rolling 365-day minimum of 8 degrees Fahrenheit signals extreme cold at altitude during deep winter. Wind averages 12 mph over 30 days but peaks near 33 mph in afternoon wind events driven by pressure gradients between the high Sierra and lower basins. Crowding remains light (rolling 30-day average of 3 out of 10) because of technical terrain and avalanche exposure. Summer brings warmer temperatures but also afternoon thunderstorms and rockfall risk.
North Notch suits experienced mountaineers and ski mountaineers with avalanche awareness and winter navigation skills. Crampon and ice axe competency is mandatory in spring; dry rock scrambling is possible in late summer and early fall. Most visitors plan for predawn starts and plan to summit by 10 a.m. before afternoon wind and cloud development. Parking is limited; arrive before sunrise or expect to backtrack. Avalanche terrain dominates the approach and summit cone; check the Sierra Avalanche Center forecast before every trip. The peak offers no shelter and no water; self-sufficiency is non-negotiable.
Cathedral Peak and Matthes Crest, both in the same range, offer comparable high-alpine exposure but slightly lower elevation and marginally lower wind pressure. Tenaya Lake, immediately west, provides a lower-altitude bail-out and is passable by car in summer and fall. Visitors considering North Notch should pair it with Cathedral Range explorations or use it as a navigation checkpoint on longer traverses. Solo ascents are rare; most trips involve parties of two or more for safety and route-finding.
