Glacier Notch
Peak · 13,768 ft · Eastern Sierra corridor
Glacier Notch is a 13,768-foot peak in California's Eastern Sierra, sitting at the margin between high alpine and glaciated terrain. Wind and cold dominate the summit experience.
Wind arrives predictably in the afternoon, funneling up the eastern drainage. Temperatures stay below freezing for much of the year. Early morning offers the calmest window and the best visibility across the Sierra crest. Afternoon wind routinely exceeds 20 mph.
Over the last 30 days, Glacier Notch averaged 12 mph wind and 19 degrees Fahrenheit, with afternoon gusts reaching 46 mph on the worst days. The coming week should hold to that pattern: calm pre-dawn hours, rising wind by midday, and sustained cold. Check the NoGo Score grid before committing to a summit push.

About Glacier Notch
Glacier Notch sits on the crest of the Eastern Sierra, accessible primarily from the Inyo County side via US Highway 395. The peak straddles avalanche terrain and requires winter mountaineering skill when snow is present. Most parties approach via Inyo National Forest trailheads in the Bishop or Big Pine drainage, with drive times of 60 to 90 minutes from Highway 395 corridor towns. The notch itself is a low point on the ridge connecting two higher summits and serves as a col for ski traverses and mountaineering routes. Elevation gain and technical scrambling make this a destination for experienced high-Sierra hikers and climbers, not casual day-hikers.
Glacier Notch sits in one of the coldest, windiest zones of the Sierra crest. The 30-day average wind of 12 mph understates the afternoon wind spike; max gusts hit 46 mph regularly. Temperatures range from 5 degrees Fahrenheit in winter to 32 degrees in summer, meaning conditions shift radically with season and time of day. Snow persists into early summer, and avalanche hazard in adjacent gullies is a constant consideration during spring. Late September through October offer the best combination of stable snow and moderate wind, though the window is narrow. Winter approaches demand current avalanche forecasts and solid snowpack assessment.
Glacier Notch suits mountaineers, ski tourers, and experienced ridge walkers aiming for the surrounding peaks. The notch itself is a waypoint rather than a destination, but the views into the Owens Valley and across the Sierra crest are unobstructed. Parking at trailheads fills quickly on weekends in the brief shoulder seasons. Wind and cold mean afternoon summits are rare; start before dawn and expect to descend by early afternoon as gusts accelerate. The 2.0 average crowding score is misleading: the few who come arrive in tight clusters around favorable weather windows.
Nearby peaks include Norman Clyde Peak and the White Mountains, which offer similar high-altitude experience with slightly more established summer access. Big Pine Lakes basin to the south provides a lower, more forgiving alternative if Glacier Notch conditions are marginal. The Eastern Sierra corridor as a whole benefits from Highway 395's proximity and town infrastructure in Bishop and Big Pine, making a base-and-raid strategy practical for back-to-back summits. Consult ESAC avalanche forecasts before any winter or spring approach.
