Andrews Mountain
Peak · 9,432 ft · Eastern Sierra corridor
Andrews Mountain is a 9,432-foot peak in the Eastern Sierra corridor, situated in avalanche terrain with exposure to afternoon wind funneling off the high desert. Colder and windier than lower Inyo County summits.
Wind dominates the afternoon and evening; mornings are typically calmer. The peak sits above 9,400 feet with unrestricted exposure to westerlies accelerating off the Sierra crest. Temperature swings sharply with elevation and time of day. Spring snowpack remains unstable on steeper aspects; assess slope angle and recent wind loading before committing to steep terrain.
Over the last 30 days, Andrews Mountain averaged 12 mph wind and 45 degrees Fahrenheit, with peak gusts reaching 32 mph. The NoGo Score averaged 36, meaning conditions have favored calm mornings and high-wind afternoons. The week ahead continues this pattern; plan for dawn starts and expect increasing wind by mid-day.

About Andrews Mountain
Andrews Mountain sits in the high Eastern Sierra corridor of California's Sierra Nevada, east of the Sierra crest at 37.08 degrees north latitude and 118.08 degrees west longitude. The peak is accessed via Highway 395 from the Inyo County side; gateway towns include Bishop and Independence. The mountain lies within avalanche terrain tracked by the Eastern Sierra Avalanche Center. This is a climbing and scrambling destination requiring off-trail approach work and route-finding; there is no maintained trail to the summit. Parking is limited and informal; approach typically takes 3 to 4 hours from Highway 395 trailheads.
Spring and early summer bring unstable snowpack and high avalanche hazard on steep north and east-facing slopes above 9,000 feet. Temperatures average 45 degrees Fahrenheit over the last 30 days, with a 365-day low of 30 degrees and high of 62 degrees; expect freezing nights and mild afternoons from late spring through early autumn. Wind averages 12 mph with gusts to 32 mph, concentrated in the afternoon and evening; mornings are markedly calmer. Crowding is minimal year-round, averaging 2 out of 10. By late September, snowpack consolidates and avalanche hazard drops sharply, making the peak more approachable for climbers comfortable with scrambling and moderate exposure.
Andrews Mountain suits climbers and scramblers with mountain travel experience and comfort on steep, exposed terrain. Visitors should carry an avalanche beacon and shovel during spring and early summer. Plan for dawn starts to avoid afternoon wind, which accelerates rapidly after mid-day and can exceed 30 mph by evening. The 32 mph maximum wind recorded over the past year underscores the exposure; afternoon wind can make steep scrambling dicey and descent treacherous. Solitude is nearly guaranteed, but isolation also means self-rescue; do not attempt the peak if conditions are marginal or if you lack experience assessing snow stability and route hazard.
Nearby peaks in the Eastern Sierra corridor include White Mountain (14,246 feet, north), with lower avalanche hazard but longer approach and colder temperature profile, and Inyo Mountain (11,149 feet, south), which offers similar exposure but shorter approach and lower technical difficulty. Andrews Mountain's combination of high elevation, avalanche terrain, and afternoon wind funneling makes it a destination for experienced climbers planning off-season ascents. Late September through early October, when snowpack is gone but before winter storms return, offers the best balance of stability, temperature, and wind conditions for this exposed summit.
