Benson Pass
Peak · 10,141 ft · Yosemite corridor
Benson Pass sits at 10,141 feet in the Yosemite Sierra Nevada corridor, a windswept high-country crossing exposed to afternoon funneling off adjacent drainages. Snow-fed approach terrain requires avalanche awareness through spring.
Wind dominates here. Morning calm typically gives way to sustained afternoon gusts funneling through the pass by mid-day. Exposed ridgeline means full exposure to Sierra weather patterns. Temperature swings are sharp between sunlit and shaded aspects, especially in spring when snowpack still covers most terrain.
Over the last 30 days, Benson Pass averaged a NoGo Score of 33.0 with winds averaging 11 mph and temperatures at 25 degrees Fahrenheit. Conditions have ranged from a low score of 6.0 to a high of 50.0, signalling high variability typical of spring transition. Watch the next week for temperature and wind trends as the season shifts; mornings remain your best window before afternoon wind builds.

About Benson Pass
Benson Pass is a high-altitude crossing in California's Sierra Nevada, part of the Yosemite corridor's network of peaks and passes above 10,000 feet. It sits at 10,141 feet elevation on the boundary between major drainage basins. Primary access is via Highway 120 from the west (Tioga Pass approach) or Highway 395 from the east. The nearest major trailheads and staging areas lie in the Lee Vining and Mammoth Lakes region to the east, and Tuolumne Meadows to the west. Approach routes are snow-choked from autumn through late spring; Highway 120 often closes seasonally. Winter and early spring ascent requires mountaineering experience and current avalanche forecasting from the Sierra Avalanche Center.
The pass experiences dramatic seasonal character. Over a rolling 365 days, temperatures have ranged from 11 to 39 degrees Fahrenheit, with wind gusts reaching 30 mph. Winter snowpack is heavy; the approach terrain holds unstable slabs well into late spring. The 30-day average temperature of 25 degrees and average wind of 11 mph reflect current spring conditions where morning windows are narrow and afternoon wind buildup is reliable. Crowding remains low (3.0 average) due to high barriers to access: permit requirements, avalanche risk, technical terrain, and seasonal road closures. Late summer and early fall (September through early October) see the fewest wind events and most stable snowpack, though access remains restricted by permit lottery and trailhead capacity.
Benson Pass suits experienced Sierra navigators, ski mountaineers planning high-country traverses, and climbers linking peaks in the Yosemite high country. Casual day-hikers are rare due to the 10,000+ foot elevation, exposure to sustained afternoon wind, and avalanche terrain requiring beacon and probe carry. Most visits cluster into a narrow window: late September through mid-October when Highway 120 is reliably open, snowpack is stable, and afternoon wind is less punishing than spring. Plan for full-day ascents; the pass is not a turnout destination. Parking and trailhead staging are at Tioga Pass or Tuolumne Meadows depending on approach; both fill quickly on calm weekends. Bring current avalanche gear, weather radio, and be prepared to abandon ascent if afternoon wind picks up or visibility drops.
Nearby alternatives include Cathedral Lakes, Mount Dana, and the Cathedral Range traverses, all accessed from Tuolumne Meadows and offering similar high-Sierra conditions with slightly lower avalanche exposure. Mount Dana (12,388 feet) sits closer to Highway 120 and has a more direct scramble route. The Lyell-Maclure Glacier complex and Mount Lyell offer ski descents and glacier travel in the same corridor. Benson Pass differs in its role as a *crossing* rather than a destination peak; it sits on the threshold between east-side and west-side Sierra basins, making it favoured by through-hikers and ski mountaineers rather than summit seekers.
