Mine Shaft Pass
Peak · 11,168 ft · Yosemite corridor
Mine Shaft Pass is an 11,168-foot peak in the Yosemite corridor of California's Sierra Nevada, sitting at the junction of high-altitude terrain and avalanche exposure. A staging point for ridge traverses and cross-country approaches.
Wind funnels consistently through the pass; the 30-day average is 10 mph, with gusts reaching 30 mph in afternoon hours. Exposure is complete at this elevation. Morning calm windows are narrow and brief. Temperature averages 26 degrees Fahrenheit across the rolling 30 days.
Over the past 30 days, Mine Shaft Pass has averaged a NoGo Score of 34.0 with wind holding at 10 mph and temperature steady near 26 degrees Fahrenheit. The week ahead will track seasonal patterns for late April in the high Sierra: watch for afternoon wind pickup and lingering snowpack variability. Crowding remains light at an average of 3.0.

About Mine Shaft Pass
Mine Shaft Pass sits at 11,168 feet on the ridge spine of the Yosemite corridor, roughly between Tuolumne Meadows and the Cathedral Range. Access is primarily via Highway 120 from the west (Yosemite Valley side) or Highway 395 from the east, with trailheads typically 2 to 3 hours' drive from either gateway. The pass serves as a saddle for ridge walkers and mountaineers linking neighboring peaks; it is not a destination of independent trails but rather a navigational waypoint on longer high-country objectives. Winter snowpack can block direct approach until late spring, requiring avalanche awareness and route-finding skill.
Conditions at Mine Shaft Pass are defined by exposure and altitude. The 30-day rolling average wind speed of 10 mph masks significant daily swings; gusts to 30 mph occur regularly in afternoon hours, particularly when pressure systems move through the Sierra. Temperature averages 26 degrees Fahrenheit across recent weeks, with the annual low dipping to 10 degrees and highs reaching 38 degrees. Springtime (late April through early June) brings variable stability: snowpack is often present but weakening, making avalanche terrain hazardous in wind-loaded gullies and steep aspects. Summer offers the most stable window, though afternoon thermals drive wind higher. Fall conditions cool rapidly after Labor Day.
Mine Shaft Pass is best suited for experienced ridge walkers, mountaineers, and off-trail navigators with winter travel skills and avalanche awareness. The pass itself offers no shelter, no water source, and no marked camping. Visitors typically pass through as part of a larger traverse or ascent objective. Parking at trailheads near Highway 120 or 395 fills quickly on clear weekends; mid-week visits see minimal crowding (averaging 3.0 across the rolling 30 days). Wind and snowpack variability are the dominant planning constraints; head here on calm mornings in stable snow conditions, and expect to retreat if afternoon wind or instability develops. The NoGo Score of 34.0 (30-day average) reflects frequent marginal-to-poor conditions; scores of 6 to 50 across the rolling window show high variability day to day.
Nearby alternatives include Cathedral Lakes Basin to the southeast, which offers established trail access and lower avalanche exposure but similar wind exposure at altitude. Tenaya Lake, 3 to 4 hours west via Highway 120, sits at lower elevation and experiences calmer afternoon conditions. For ridge walkers comfortable with snowpack and navigation, the Cathedral Range traverse links multiple summits and uses Mine Shaft Pass as a natural saddle; this is a multi-day objective requiring backcountry experience. Avoid the pass in poor visibility, during rapid snowmelt, or in the 48 hours following fresh snow when avalanche danger in nearby terrain is elevated.
