Butt Mountain
Peak · 7,857 ft · North Sierra corridor
Butt Mountain is a 7,857-foot peak in the North Sierra corridor with direct exposure to afternoon wind funnels and substantial avalanche terrain. Access via Highway 89 corridor from the west.
Wind builds from calm mornings to 15+ mph by mid-afternoon; the peak sits in a wind corridor that channels gusts off the high desert plateau. Expect colder temperatures than lower Sierra elevations. Winter snowpack remains unstable through spring; avoid steep slopes without checking the avalanche forecast from the Sacramento Avalanche Center.
Over the past 30 days, the 30-day average wind was 10 mph, with gusts reaching 22 mph; the average temperature held at 33 degrees Fahrenheit and crowding remained light at 5 per session. The week ahead shows typical spring volatility. Plan morning departures and monitor avalanche advisories before any winter or early-spring visit.

About Butt Mountain
Butt Mountain sits at 7,857 feet in the North Sierra, positioned in the high-elevation corridor between Lake Tahoe and the Modoc Plateau. Access is via Highway 89 from the west (Susanville is the nearest gateway town, roughly 90 minutes to the north). The peak stands in open, exposed terrain with no tree shelter on the summit approach. Winter and spring require understanding of avalanche exposure; the Sacramento Avalanche Center issues forecasts for this zone. Summer approach is straightforward but expect afternoon wind. The location sits well inland from the Sierra crest, placing it drier and windier than west-slope peaks.
Butt Mountain experiences pronounced afternoon wind acceleration, typical of interior high-Sierra locations. The 30-day rolling average wind of 10 mph masks a pattern: calm before 10 a.m., building steadily through midday, peaking 3 to 6 p.m. with gusts to 22 mph. Temperatures average 33 degrees Fahrenheit over the past month, ranging from lows near 19 degrees to highs near 47 degrees across the full year. Crowding remains sparse (5 people per session on average), reflecting the remote location and limited summer recreation. Spring and early summer bring rapid snowpack transition; avalanche terrain is extensive and active until late spring.
Butt Mountain suits hikers, scramblers, and backcountry skiers willing to plan around wind and avalanche hazard. Experienced winter mountaineers visit for spring ski descents on longer corn cycles, but require detailed avalanche awareness and stable snowpack confirmation. Summer weekday visits are calmest; avoid afternoons. Weekend traffic is minimal but crowds spike the first week after Highway 89 opens in late spring. Parking is dispersed trailhead access; arrive early on any weekend. Wind-sensitive users (paragliders, ultralight climbers) should target Tuesday to Thursday mornings in stable weather windows.
Nearby alternatives in the North Sierra corridor include higher Modoc Plateau peaks to the east and the Castle Crags massif to the northwest. Butt Mountain lacks the established trail infrastructure of more famous Sierra destinations but rewards self-reliant visitors with solitude and direct exposure to authentic high-desert conditions. The peak's prominence and open terrain make it a strong training ground for avalanche-prone terrain recognition before pursuing steeper North Sierra objectives.
