Ice Lake Pass
Peak · 10,098 ft · Yosemite corridor
Ice Lake Pass sits at 10,098 feet in the Yosemite Sierra corridor, a windswept alpine crossing between the high peaks. Wind funnels through the pass relentlessly, making it colder and more exposed than sheltered valleys below.
Wind dominates at Ice Lake Pass. The 30-day average wind of 15 mph masks gusts that spike to 42 mph, especially on afternoons and clear days when thermals accelerate flow through the gap. Mornings are calmer. Temperature swings between 7 degrees in winter and 34 degrees in summer; expect cold even in mid-day.
Over the past 30 days, Ice Lake Pass has averaged a NoGo Score of 33 with wind at 15 mph and crowding light at 3.0. The high-elevation exposure and avalanche terrain mean conditions swing fast; tracking the week ahead matters more than seasonal generalities. Watch for warming cycles that destabilize snowpack and wind pulses that make travel unsafe.

About Ice Lake Pass
Ice Lake Pass lies in the Yosemite corridor of California's high Sierra, accessed via Highway 120 from the west or Highway 395 corridors from the east. The pass sits at the headwaters of the Lyell Fork drainage and connects remote backcountry. Most parties approach from the Highway 120 corridor in summer and early fall; winter and spring travel requires avalanche training and careful snowpack assessment. The pass marks a major saddle between prominent peaks; it is exposed and windswept year-round.
Conditions at Ice Lake Pass reflect its elevation and funnel geography. The 30-day average temperature of 21 degrees Fahrenheit is substantially colder than Yosemite Valley at the same time; wind averaging 15 mph with gusts to 42 mph makes it colder still. Crowding averages 3.0 on the rolling 30-day window, indicating light use and fewer weather buffers from other users. Spring and early summer bring unstable snowpack and avalanche risk; the location sits in terrain with slopes exceeding 30 degrees. By late summer, snow recedes but wind intensifies. Autumn brings brief calm windows. Winter closes access for most parties.
Ice Lake Pass suits experienced mountaineers and backcountry skiers with avalanche rescue training and route-finding skill. The high elevation and wind exposure mean parties plan for cold, carry layers, and avoid afternoons when wind and thermals peak. Climbers tackling nearby peaks often stage through the pass. Backpackers use it as a transit point between east and west Sierra. The light crowding means solitude but also isolation; self-rescue capability is essential. Snow presence dictates feasibility; summer crossings demand careful route finding to avoid cornices and steep descents.
Nearby alternatives include lower passes in the Yosemite corridor that offer less wind and warmer conditions, though they see more traffic. Adjacent peaks such as Lyell and Maclure demand similar high-alpine skill and reward with similar isolation. Parties heading to the Evolution Basin or Muir Trail often plan around Ice Lake Pass as a barrier or waypoint, treating it as a gateway rather than a destination. Consulting the Mono Basin Avalanche Center forecasts and Highway 120 closure status is essential before committing to the approach.
