Old Man Mountain
Peak · 7,749 ft · Lake Tahoe corridor
Old Man Mountain is a 7,749-foot peak in the Lake Tahoe corridor's high Sierra Nevada. Wind and avalanche terrain define the approach; the summit commands views across the basin.
Wind dominates afternoons, funneling off the lake surface by mid-day. Morning hours are calmer and warmer relative to exposed ridges nearby. Snowpack persists into late spring; assess stability before committing to steep terrain.
Over the last 30 days, Old Man Mountain averaged 9 mph wind and a NoGo Score of 42, with a high of 65 and low of 5. Temperatures averaged 33 degrees Fahrenheit. The week ahead will follow typical spring patterns: calm mornings, rising wind by afternoon, and continued snowpack in shadowed drainages. Check the SAC avalanche forecast before any winter or early-spring approach.

About Old Man Mountain
Old Man Mountain sits at the eastern fringe of the Lake Tahoe corridor's high-elevation terrain, approximately 30 road miles from South Lake Tahoe via Highway 50 and local access roads. The peak is accessed from trailheads on the east or northeast; approach via the El Dorado County side is most direct. The mountain is popular with backcountry skiers and winter climbers during stable snow periods, and hikers in summer months when snow has cleared. Base popularity is low relative to nearby Carson Pass or peaks bordering the main lake basin, making Old Man Mountain a less-crowded option for experienced off-trail travel.
The 30-day rolling average temperature of 33 degrees masks significant daily and seasonal swings. Winter through early spring, overnight lows drop below 21 degrees; summer highs reach the upper 40s. Wind averages 9 mph but spikes to 23 mph in afternoon and evening hours, particularly when the lake surface is warmed and lake-breeze circulation strengthens. Crowding averages 2.0 across the rolling 30-day window, reflecting a smaller visitor base relative to Highway 50 corridor benchmarks. Spring and early summer are the busiest periods. Expect minimal crowds in mid-winter or late autumn.
Old Man Mountain suits experienced backcountry skiers and off-trail hikers comfortable navigating avalanche terrain. The peak has significant steep slopes facing north and east; stable snowpack can be present until July in shadowed aspects. Visitors should carry avalanche beacon, probe, and shovel during winter and spring. Morning windows before 11 a.m. offer the best wind conditions and least afternoon turbulence. Afternoon wind gusts to 23 mph can make exposed traverses exposed and crossing gullies hazardous. Plan a dawn or early-morning departure and descent before mid-afternoon.
Nearby Thimble Peak and the Carson Pass backcountry complex offer comparable terrain and snow stability. The Red Lake Peak area to the south sees heavier traffic. Old Man Mountain appeals to parties seeking a less-crowded high-Sierra experience with proven avalanche education and self-rescue capability. SAC forecasts are mandatory consultation; spring wet-slab and wind-slab hazards are common. Confirm road access to trailheads before committing a trip; late spring snow closure can persist on unpaved approach roads.
