Scimitar Pass
Peak · 13,218 ft · Eastern Sierra corridor
Scimitar Pass is a 13,218-foot peak in the Eastern Sierra, sitting above the high-desert transition zone where afternoon winds accelerate off the lake basins. Low base popularity means solitude, but avalanche terrain demands winter caution.
Wind dominates the afternoon window; the 30-day average of 12 mph underscores persistent funnelling off the eastern Sierra drainage systems. Morning calm is real but brief. Temperature swing from single digits to low 30s Fahrenheit across seasons means layer changes are mandatory, not optional.
Over the last 30 days, Scimitar Pass has averaged a NoGo Score of 36, with temperatures hovering around 19 degrees Fahrenheit and wind averaging 12 mph. The week ahead will show whether the spring pattern holds stable or whether afternoon thermal winds drive scores higher. Check the trend chart to spot the narrow morning windows and plan approaches accordingly.

About Scimitar Pass
Scimitar Pass sits at 13,218 feet in the Eastern Sierra corridor of California's Sierra Nevada, positioned above the high-desert transition where drainage wind funnels from the alpine lakes and meadows below. Access is via U.S. Highway 395 through the Mammoth Lakes gateway or from the north via U.S. Highway 120 and Tioga Pass. The pass itself is best reached as part of a high-country traverse or mountaineering objective rather than a casual dayhike; parking and trailheads depend on the specific route you choose from the surrounding wilderness. Base popularity is low (0.2), which means crowds are not a factor, but remote access and high elevation demand solid route-finding and self-sufficiency.
Winter and early spring dominate the calendar here. The 365-day rolling stats show temperatures ranging from a low of 5 degrees Fahrenheit to a high of 32 degrees, confirming the pass remains in deep snow and instability from late autumn through late spring. The 30-day average temperature of 19 degrees and average wind of 12 mph reflect the current shoulder season; afternoon wind speeds routinely reach 46 mph at the pass, driven by thermal heating of the desert basins to the east. Crowding averages just 2 across the rolling 30 days, meaning solitude is nearly guaranteed. Late September through October marks the clearest, calmest window; by November, snowpack instability and avalanche risk climb sharply, and the pass becomes a winter mountaineering objective requiring avalanche knowledge and proper gear.
This pass is for experienced mountaineers and backcountry skiers comfortable with avalanche terrain and high-altitude exposure. The Eastern Sierra Avalanche Center (ESAC) maintains hazard forecasts specific to this zone; check conditions before any winter or spring approach. Typical visitors are attempting high-Sierra traverses, ski descents, or peak ascents rather than casual hikers. Plan for multi-day travel or significant elevation gain from the nearest trail; water sources are scarce at elevation, and weather can isolate the pass in minutes. The low base popularity and remote access mean you should carry redundant navigation and communication tools.
Nearby alternatives in the Eastern Sierra corridor include higher-traffic passes and peaks accessed via U.S. Highway 395 closer to Mammoth Lakes and the June Lake Loop, where parking and crowds are heavier but conditions are more frequently monitored. Scimitar Pass itself is better paired with adjacent objectives in the Sierra crest than visited in isolation. If you're seeking alpine solitude with extreme exposure and avalanche terrain, this pass rewards preparation and early-season timing; if you want convenient day access and reliable services, the lower eastern Sierra peaks and meadows near Highway 395 will suit you better.
