Mount Ingalls
Peak · 8,339 ft · North Sierra corridor
Mount Ingalls is an 8,339-foot peak in California's North Sierra corridor, accessed via the Donner Pass region. Wind-exposed and avalanche-terrain-laden, it demands cold-weather timing and stable snowpack.
Wind averages 12 mph but routinely gusts to 30 mph, peaking mid-afternoon. Afternoon thermals and lake-induced flows funnel up from the west. Morning windows are calmer. At 8,339 feet, temperature runs 31 degrees Fahrenheit on average; expect frozen conditions well into spring and unstable slabs after rapid warm spells.
The last 30 days averaged a 35 NoGo Score with wind holding at 12 mph and temperatures near 31 degrees Fahrenheit. Crowding remains minimal at 5 on the 1 to 10 scale. The week ahead shows typical spring volatility: watch for wind spikes tied to afternoon heating and avalanche-hazard swings following precipitation or warm days. Stable mornings in the 7 to 10 day window offer the best climbing windows.

About Mount Ingalls
Mount Ingalls sits in the North Sierra corridor east of Interstate 80 and the Donner Pass region, roughly 90 minutes northeast of Sacramento. The peak is part of the high-Sierra granite crest separating the Nevada side from the western slope. Primary access follows Highway 89 north from Truckee or Sierraville; the peak is typically climbed via the Sierra Buttes drainage or approach from the Sardine Lake area to the north. Winter and spring ascents require a car that handles snow and chains, plus parking discipline at popular trailheads.
Elevation at 8,339 feet places Mount Ingalls in the zone where spring arrives late and lingers unpredictably. The 30-day average temperature of 31 degrees Fahrenheit reflects lingering snowpack and frequent night freezes through late spring. Wind averages 12 mph but can spike to 30 mph in afternoon thermals, a pattern strongest on clear, high-pressure days. Crowding stays low at 5 on the scale; most traffic arrives during holiday weekends or immediately after major storms clear. Late September through October sees the lowest wind, stable snowpack already established for the season, and pleasant single-digit crowding.
Mount Ingalls suits climbers comfortable with exposed granite, snowpack evaluation, and avalanche-terrain recognition. Parties should carry a shovel, probe, and beacon in winter and spring; the peak sits in Shasta-Trinity and American River drainages with active slide paths on the north and east faces. Experienced scrambler parties can summit in a day from Sardine Lake trailhead, but route-finding through snowfields requires map work and compass skills. Avoid the peak in late winter after heavy wet snow without a full avalanche assessment from the Sacramento Avalanche Center.
Nearby alternatives include Sierra Buttes to the south, slightly lower and equally exposed but with a fire-lookout summit facility. Castle Peak lies west across Highway 89 and offers similar elevation with better-protected approaches. The Donner Pass corridor itself (Donner Peak, Castle Peak, Anderson Peak) provides high-elevation scrambles with better parking infrastructure but sees heavier weekend traffic. Mount Ingalls appeals to parties seeking solitude in the North Sierra high country and willing to plan around wind and avalanche hazard.
