Cottonwood Mountain
Peak · 6,394 ft · North Sierra corridor
Cottonwood Mountain is a 6394 ft peak in the North Sierra corridor, exposed to afternoon wind funnels off the adjacent high country. Wind-prone and sparsely visited compared to Highway 89 corridor peaks.
Afternoon wind dominates here. The 30-day average wind of 13 mph spikes sharply after mid-day, with gusts reaching 27 mph in typical spring conditions. Morning calm windows close by early afternoon. Exposure to lake-effect flow and open slopes above tree line make this place notably windier than sheltered lake coves.
Over the last 30 days, Cottonwood Mountain has averaged a NoGo Score of 35 with temperatures near 39 degrees Fahrenheit and wind around 13 mph. Crowding remains minimal at 5 visitors per day. The week ahead reflects typical spring patterns: expect morning windows to narrow and afternoon gusts to intensify as the high-pressure pattern establishes.

About Cottonwood Mountain
Cottonwood Mountain sits at 6394 feet in the North Sierra, east of the main crest and accessible from Highway 395 near the Susanville corridor. The peak rises above sagebrush and scattered pine, exposed to the wind patterns that sweep off the open high desert to the east. Primary approach follows Forest Service roads from the Highway 395 gateway; a high-clearance vehicle is typically required, and snow blocks access from November through April. The peak is part of the Lassen Volcanic National Forest jurisdiction; check Modoc National Forest conditions before departure as snow and road closures vary dramatically by week.
Cottonwood Mountain experiences pronounced seasonal extremes typical of the high Sierra rain shadow. Winter temperatures drop to 23 degrees Fahrenheit on average and the peak sits above intermittent snow; avalanche terrain is present on steeper gullies and the peak itself lies in SAC avalanche center jurisdiction, requiring snowpack assessment before winter ascents. Spring and early summer (April through early July) bring the most variable conditions: temperatures average 39 degrees Fahrenheit, wind averages 13 mph but frequently exceeds 27 mph by afternoon, and the transition from snow to exposed rock happens over just a few weeks. Summer (July through September) is calmer and warmer, with temperatures reaching 57 degrees Fahrenheit on average, and offers the most stable wind windows. Autumn sees rapid cooling and the first significant snow events arrive by late September.
Cottonwood Mountain suits hikers and scramblers comfortable with exposed ridges and wind-driven conditions. The rolling 30-day crowding average is 5 visitors per day, making it substantially quieter than Lassen Peak or the Highway 89 corridor peaks. Experienced visitors time ascents for dawn departures and plan to descend before noon, as afternoon wind gusts to 27 mph render the exposed summit and ridges uncomfortable and hazardous. Winter climbers and ski mountaineers must carry avalanche safety gear and be proficient in snowpack evaluation; the SAC avalanche center provides regular forecasts. Parking is limited and dispersed; arrive early if traveling on weekends April through early June.
Cottonwood Mountain's isolation and wind exposure make it a deliberate choice rather than a convenient peak. Nearby Highway 395 peaks offer lower elevation and less wind; Susanville and Chester are the closest supply towns. The peak pairs well with multi-day desert-to-Sierra traverses but is rarely a day-trip destination for Bay Area or Sacramento visitors. For similar elevation and forest access with lower wind exposure, the neighboring corridor peaks along Highway 89 near Mount Lassen are more sheltered.
