Cottonwood Peak
Peak · 6,535 ft · North Sierra corridor
Cottonwood Peak is a 6535-foot summit in the North Sierra corridor east of Lake Tahoe. Exposed to wind funneling from the high desert, it demands careful timing and avalanche awareness in winter.
Wind dominates here, averaging 13 mph over the last month with gusts to 30 mph. Morning calm windows close by midday. Avalanche terrain is present; spring snowpack instability and wind-loading create slides on steep couloirs. Check SAC forecasts before any winter approach.
Over the last 30 days, Cottonwood Peak averaged a NoGo Score of 35 with temperatures around 40°F and 13 mph wind. The coming week will show how wind and warming interact as spring advances. Crowding remains light at 5 on the 30-day average, so solitude is typical unless access roads open wide.

About Cottonwood Peak
Cottonwood Peak sits in the North Sierra at 6535 feet, roughly 45 minutes northeast of Truckee via Highway 89 toward the high desert plateau. The peak anchors a cluster of peaks separating the Tahoe Basin from the Smoke Creek drainage to the east. Access is primarily via Cottonwood Creek Road or jeep tracks from the Gerlach side; roads are gated or snow-blocked much of the year. Spring and early summer are the traditional windows when snow melts enough to permit vehicle or foot approach. Summer access is simplest, but crowds pick up on clear weekends once Highway 80 and 89 fully open.
The 30-day average wind of 13 mph masks strong diurnal swings. Early mornings are often calm; wind picks up sharply between 11 am and 2 pm as thermal circulation strengthens and high-desert air masses funnel westward off the Nevada plains. Temperatures average 40°F over the rolling month, but swing from a year-round minimum of 23°F in deep winter to a maximum of 58°F in summer. Snowpack persists well into May; avalanche terrain includes steep north-facing gullies where wind-loading and rapid spring warming create slab hazard. The SAC avalanche center covers this area; late-morning and afternoon ascents in spring are higher-risk than dawn starts.
Cottonwood Peak suits experienced mountaineers and backcountry skiers comfortable with route-finding and avalanche hazard assessment. Snow climbers come for the moderate north-aspect couloirs and the solitude. Summer scramblers find a straightforward high-desert route with views across Nevada. Parking at the trailhead is limited and often occupied only on weekends; mid-week visits are quieter. Expect loose volcanic rock and scree in summer, and plan for water scarcity in the high desert environment. Mobile service is spotty; carry a satellite communicator if venturing off the main ridge.
Nearby peaks in the North Sierra corridor include Castle Peak and Andesite Peak to the west, both more accessible and slightly lower. The Sierra Crest to the south (around Lassen Volcanic National Park) sees heavier snow and longer winter closure. Cottonwood Peak's draw is its position straddling the Sierra divide with direct exposure to eastern wind patterns; it is calmer than exposed lake ridges to the west but windier than protected valleys. Spring ascents pair well with exploring the high-desert ecology; summer routes benefit from the low crowding and easier parking compared to Tahoe-adjacent peaks.
