Shellenbarger Lake
Lake · 9,819 ft · Yosemite corridor
Shellenbarger Lake sits at 9,819 feet in the Yosemite corridor of California's Sierra Nevada. This high-elevation cirque lake straddles the transition zone between alpine meadow and persistent snowpack, drawing backcountry hikers and snow-travel parties to its glacially-sculpted basin.
Wind typically averages 9 mph over rolling 30 days but accelerates to 29 mph on exposed afternoons. Morning calm persists until mid-day; afternoon gusts funnel down the drainage. Temperature hovers near 29 degrees Fahrenheit on average, with snowpack lingering well into the season. Crowds remain low; expect solitude even on weekends.
Over the last 30 days, conditions have averaged a NoGo Score of 34 with mean wind of 9 mph and temperatures near 29 degrees Fahrenheit. The week ahead tracks the seasonal shift from persistent snow to melt-out; wind gusts will peak in afternoon hours. Reference the chart below to spot your best window: lower scores indicate calmer, more stable days for alpine travel.

About Shellenbarger Lake
Shellenbarger Lake occupies a remote cirque at 9,819 feet in the high Sierra, accessible via Highway 120 (Tioga Pass Road) east of Yosemite National Park. The lake drains north into the Mono Basin. Primary access runs through the Lee Vining or Mammoth Lakes corridor, with trailheads typically 1.5 to 3 hours' drive from the valley floor. Winter closure of Highway 120 forces a long southern approach via Highway 395 and Highway 203; most summer-season visitors depart from the Tuolumne Meadows area or Mono Basin approach routes.
Shellenbarger sits squarely in avalanche terrain. The rolling 30-day average temperature of 29 degrees Fahrenheit signals deep winter persistence; snowpack averages higher here than at lower Yosemite elevations. Wind averages 9 mph but spikes to 29 mph on exposed afternoons, creating wind-slab and loading conditions that demand avalanche-awareness and route-finding skill. Crowding averages just 6 out of 100 over the rolling month, a stark contrast to Yosemite Valley's peak-season press. Late-season trips (after peak snowmelt) see calmer wind and more stable snow, though the 365-day maximum wind remains 29 mph even in summer.
Shellenbarger Lake suits experienced alpine backpackers, ski mountaineers, and snow-travel parties familiar with avalanche terrain assessment. The low base popularity and high altitude isolate the lake from casual day-hikers. Visitors plan around persistent snowpack and wind-driven conditions; afternoon wind is nearly inevitable, so early alpine starts are mandatory. Parking at trailheads fills during brief summer windows; arrive by dawn or plan a weekday visit. The place demands solid navigation, emergency communication capability, and willingness to retreat if conditions deteriorate.
Nearby alternatives include Mono Lake's alpine tributary lakes and the Cathedral Range cirques to the west, each offering similar elevation but varied access difficulty. Shellenbarger's advantage is its remoteness; the trade-off is exposed terrain and avalanche hazard. Experienced winter mountaineers often stage Shellenbarger as part of multi-day High Sierra traverses linking the Mono Divide to the Lyell Massif.
