Starbolator Pass
Peak · 10,862 ft · Yosemite corridor
Starbolator Pass is a 10,862-foot summit in the Yosemite corridor of California's Sierra Nevada, sitting at the threshold between glaciated terrain and exposed alpine ridge. Wind and avalanche terrain define the crossing.
Expect sustained wind in the 12 mph range with frequent gusts to 36 mph. Temperature averages 24 degrees Fahrenheit over the rolling month. Mornings are calmer; afternoon wind funnels through the pass by midday. Snowpack persists through spring; assess slope stability before crossing avalanche terrain.
Over the last 30 days, Starbolator Pass averaged a NoGo Score of 34, with wind holding at 12 mph and temperatures averaging 24 degrees Fahrenheit. The week ahead mirrors that pattern. Plan for sustained afternoon wind and persistent winter conditions; early morning departure is non-negotiable for safe passage through avalanche slopes.

About Starbolator Pass
Starbolator Pass sits at 10,862 feet in the high Sierra, accessible via Highway 120 (Tioga Pass Road) from the west. The pass marks a major drainage divide in the Yosemite corridor, lying east of the Sierra crest proper. Approach from Tenaya Lake or the Tioga Pass corridor depending on your route. The gateway town is Lee Vining on the east side (Highway 395) or Yosemite Valley to the west. Drive time from Valley to trailhead is roughly 90 minutes via Highway 120.
Winter and spring conditions dominate Starbolator Pass. Snow lingers through April and into May; avalanche terrain flanks the approach and summit slopes. The 30-day average temperature of 24 degrees Fahrenheit reflects persistent alpine cold. Wind averages 12 mph but regularly spikes to 36 mph in afternoon flow. Crowding remains light (average 3.0 on the rolling month), a function of snow closure and technical terrain. Summer opens the pass fully; by late September, conditions stabilize and crowds thin. Expect variable snow through May; dry, safer conditions arrive in July.
This pass suits experienced winter mountaineers and spring ski tourers with avalanche training. Standard users are self-sufficient parties comfortable with navigation in whiteout, slope assessment, and self-rescue. Afternoon wind makes morning departure essential; plan to cross before midday. Avalanche beacon, probe, and shovel are mandatory in spring. Parking is scattered near Tioga Pass Road trailheads; arrive early or plan midweek to avoid bottlenecks. Bring extra layers; the 30-day average of 24 degrees underestimates wind chill on exposed slopes.
Nearby alternatives include passes to the south (Mono Pass, Kearsarge Pass) and north (Glen Aulin/Cathedral Pass). Starbolator is more exposed and wind-prone than Kearsarge and typically snowier earlier in the season than Mono. Tioga Pass (Highway 120 direct crossing) avoids avalanche terrain but is closed seasonally. Mount Dana, adjacent to Starbolator on the crest, offers similar conditions and slightly higher elevation. For low-snow conditions and lighter crowds, wait until late September when both wind and avalanche hazard drop.
