Vernon Pass
Peak · 12,188 ft · Yosemite corridor
Vernon Pass is a 12,188-foot summit in the Yosemite corridor of California's Sierra Nevada. The peak straddles avalanche terrain and sits exposed to afternoon wind funnels from the eastern slope.
Wind picks up sharply between midday and evening, averaging 12 mph over the last month with gusts to 40 mph. Temperature hovers around 22 degrees Fahrenheit in the rolling 30-day window. Morning windows are markedly calmer; afternoon approaches require wind awareness and avalanche assessment.
Over the last 30 days, Vernon Pass averaged a NoGo Score of 33.0 with wind averaging 12 mph and temperature at 22 degrees Fahrenheit. The week ahead continues this pattern of morning stability deteriorating into afternoon wind. Watch for gusts exceeding 30 mph by mid-day and assess snowpack carefully before any ascent.

About Vernon Pass
Vernon Pass sits at the head of the Yosemite corridor, accessible via Highway 120 from the west (Lee Vining approach) or Highway 395 from the east. The peak's 12,188-foot elevation places it in the high-Sierra wind belt. Most visits originate from the Highway 120 corridor during snow-free or early-season windows. Parking near the pass is minimal and fills quickly on weekends. The SAC avalanche center maintains assessment authority for this terrain. Access typically requires a 2 to 4 hour approach depending on snowpack and route choice.
Vernon Pass behaves as a wind-exposed, high-elevation alpine point. The 30-day rolling average wind is 12 mph with frequent gusts exceeding 30 mph by afternoon; the maximum recorded wind in the 30-day window reached 40 mph. Temperature averages 22 degrees Fahrenheit across the same period, ranging from single digits in winter to the mid-30s in summer across the full-year window. Crowding remains low at a 3.0 rating over 30 days, reflecting the peak's remote location and technical approach. Spring and early summer (late May through July) offer the most stable snow conditions and longest daylight, but afternoon winds strengthen reliably after 1 p.m. Winter approaches require avalanche beacon and probe; corniced ridges are common.
Vernon Pass suits experienced alpinists comfortable with exposed terrain, avalanche assessment, and rapid weather change. The peak is not beginner-friendly. Parties typically visit in small groups and plan ascents to clear the ridge by early afternoon. Wind-sensitive pursuits (ski touring, paragliding staging) require early-morning starts; afternoon approaches are unwise. The low base popularity (0.2) and sparse parking mean mid-week visits encounter fewer people than weekends, though the advantage is modest. Smoke from Sierra fires can obscure views and reduce visibility to critical landmarks in late summer; check air quality before committing.
Nearby peaks in the Yosemite corridor include Tioga Peak and Mount Dana, both similarly high and exposed. The Highway 120 corridor west to Tuolumne Meadows offers lower-elevation alpine lakes and passes with gentler approach grades. Mono Basin (east of Highway 395) provides alternative high-Sierra access with lower avalanche consequence in certain sub-basins. Visitors pairing Vernon Pass with a longer Sierra tour should budget extra time for wind delays and avalanche-terrain route-finding.
