Buckingham Mountain
Peak · 4,484 ft · Yosemite corridor
Buckingham Mountain is a 4484-foot Sierra Nevada peak in the Yosemite corridor with avalanche terrain and moderate seasonal access. A backcountry objective best approached in stable snow or dry conditions.
Wind averages 7 mph over rolling 30 days but peaks above 20 mph in afternoon gusts. Temperature swings from 38 degrees in winter to 65 degrees in summer. Afternoon conditions deteriorate faster than morning hours. Snowpack stability and rime ice demand caution on the approach.
The 30-day average temperature of 49 degrees and wind averaging 7 mph are near seasonal norms for this 4484-foot elevation. Over the past month, conditions have ranged from a low NoGo Score of 5 to a maximum of 50, tracking typical spring volatility as snowpack thaws and afternoon winds pick up. The week ahead shows similar variability; plan for calm mornings and increasing wind by mid-afternoon.

About Buckingham Mountain
Buckingham Mountain sits at 4484 feet in the high Sierra, part of the Yosemite corridor east of the main park boundary. Primary access is via Highway 120 from the west or Highway 395 from the east, with the peak approached from trailheads in the Tioga Pass vicinity or the Lee Vining drainage. Winter and spring approaches require competence with avalanche terrain and snowpack assessment; the location is flagged for avalanche terrain by the Sierra Avalanche Center. Summer and fall access is less technical but still exposed; navigation demands a topo map and compass. Base popularity is low (0.2 rating), meaning the peak sees minimal foot traffic even in peak season.
Temperature over a rolling 30-day window averages 49 degrees, with seasonal extremes from 38 degrees in winter to 65 degrees in summer. Wind averages 7 mph but frequently exceeds 20 mph in the afternoon; morning departure before 10 a.m. reduces exposure to the strongest gusts. Crowding averages 3 (light), concentrated in July and August when Highway 120 is fully open. Early spring and fall typically offer the best balance of stable conditions and solitude. Late September and early October combine moderate temperatures, lower wind exposure, and the fewest visitors of any non-winter period.
This peak suits winter mountaineers and spring ski tourers willing to assess avalanche hazard, as well as experienced summer scramblers looking for isolation. The low base popularity makes it a true backcountry objective, not a casual weekend destination. Experienced visitors plan around snowpack stability from December through May, afternoon wind in any season, and the short operational window of Highway 120 (typically closed November through May). Parking is roadside near the approach trailhead; crowds are minimal but solitude comes with self-reliance.
Nearby alternatives in the Yosemite corridor include higher peaks like Mount Dana and Koip Crest to the south, both more heavily trafficked but better established for winter approaches. Younger scramblers often transition from the lower Tioga Pass peaks to Buckingham Mountain as navigation and avalanche skills improve. The peak's modest elevation and technical accessibility place it squarely in the intermediate-to-advanced touring category, distinct from the more developed trails of Yosemite Valley and the open ridge traverses of the Cathedral Range to the west.
