Ericsson Pass
Peak · 12,599 ft · Eastern Sierra corridor
Ericsson Pass sits at 12,599 feet in the Eastern Sierra's high country, a windswept alpine crossing with significant avalanche terrain. Winter and spring access requires mountain sense and stable snowpack assessment.
Wind dominates here; the 30-day average of 15 mph masks gusts to 42 mph, especially mid-afternoon and during westerly flow. Temperatures average 22 degrees Fahrenheit across the rolling month. Exposure is severe. Early mornings offer the calmest windows before thermal circulation and synoptic winds peak.
Over the last 30 days, Ericsson Pass has averaged a NoGo Score of 38 with wind conditions oscillating between 8 and 65, temperatures holding near 22 degrees Fahrenheit, and minimal crowding at an average of 2. Wind gusts have reached 42 mph, typical for this elevation and aspect. The week ahead will likely see similar patterns; plan around the predictable afternoon wind ramp and monitor avalanche advisories if snowpack remains substantial.

About Ericsson Pass
Ericsson Pass is a 12,599-foot alpine saddle in the Eastern Sierra corridor, straddling the spine between the Inyo National Forest and high-desert drainage basins. Access is primarily from the east via US Highway 395, with trailhead approaches from Independence or Lone Pine, both small towns roughly 10 to 20 miles south or west. The pass itself sits in complex terrain with active avalanche paths on several flanks; it is not a casual walk-up destination. Winter and early-spring approaches require route-finding skills and stable snowpack assessment. The nearest reliable services are in Independence or Lone Pine; plan fuel, water, and navigation tools accordingly.
Weather at Ericsson Pass is shaped by its high elevation and exposed ridge position. The rolling 30-day average wind sits at 15 mph, but the 365-day record shows gusts to 42 mph are routine, particularly in spring when pressure gradients are steep. Temperature extremes span 4 degrees Fahrenheit in winter to 35 degrees in summer, with the current 30-day average near 22 degrees. Crowding is very light, averaging 2 across the month; few visitors attempt this terrain. Snowpack persists into late spring; early-season visitors must evaluate avalanche hazard and cornicing risk before committing. Afternoon winds are nearly guaranteed; morning departures significantly improve experience and safety margins.
Ericsson Pass suits mountaineers, ski-mountaineers, and experienced backcountry travelers comfortable with unmarked terrain, self-rescue capability, and avalanche awareness. This is not a destination for casual hikers. Summer parties may encounter exposed scree and lingering snowfields. Winter and spring access demands full winter kit, beacon, probe, and shovel. Parking is extremely limited; expect no facilities at the trailhead. Most visits cluster in July and August when snow is mostly gone and wind is more moderate. Late spring approaches are possible but require real-time avalanche and weather assessment from the Eastern Sierra Avalanche Center. Afternoon exposure and sustained gusts make mid-day attempts riskier than early starts.
Nearby, the Independence to Lone Pine corridor offers easier day-hike access to lower-elevation Sierra scenery and alternatives if Ericsson Pass conditions prove unsafe. Mount Whitney, roughly 20 miles south, is more crowded but better-marked. The White Mountains to the east provide high-elevation exposures with slightly different wind and avalanche patterns. Experienced parties seeking similar altitude and solitude sometimes pair Ericsson with adjacent peaks accessed via the same approach, creating extended traverses. Always confirm current avalanche and weather bulletins before committing; conditions here shift rapidly and consequence is high.
