Mount Baldwin
Peak · 12,591 ft · Mammoth Lakes corridor
Mount Baldwin is a 12,591-foot peak in the Mammoth Lakes corridor of the Sierra Nevada. The high-elevation terrain sits exposed to afternoon wind and requires winter avalanche awareness.
Wind averages 15 mph over the last month but regularly exceeds 40 mph in afternoon hours, funneling off the nearby lakes and ridges. Morning calm gives way to sustained gusts by midday. Snow lingers into early summer; assess avalanche terrain before committing to steep approaches.
The 30-day rolling average wind of 15 mph masks the real hazard: peak wind gusts reach 43 mph, typically arriving mid-afternoon. Recent temperatures average 23 degrees Fahrenheit. Head out early to avoid the wind window, or plan for a sheltered approach if you're traveling in the week ahead.

About Mount Baldwin
Mount Baldwin sits at 12,591 feet in the high Sierra east of the Mammoth Lakes basin. The peak is accessed via Highway 395 south of Mammoth; drive time from the town is under one hour. The peak's prominence and isolated position expose it to the full force of afternoon wind systems that race down from the high plateaus. Base popularity is low, which means light crowds but also minimal trail infrastructure. Winter access requires avalanche terrain knowledge; the peak sits in avalanche terrain and retains snow into late spring.
Over the last 30 days, conditions have averaged a NoGo Score of 36.0, with wind averaging 15 mph but spiking to 43 mph during afternoon hours. Temperatures average 23 degrees Fahrenheit, typical for high-elevation Sierra winter and spring. Crowding averages 2.0, indicating sparse use even during peak weekends. The elevation and exposure mean conditions can deteriorate rapidly once the afternoon wind picks up. Summer brings slightly warmer air but also thunderstorm risk and afternoon instability.
Mount Baldwin suits experienced mountaineers and winter climbers comfortable with avalanche terrain and high-altitude exposure. The low baseline popularity means you'll encounter few other parties, but also that rescue and support infrastructure are distant. Plan for dawn starts to maximize the calm window before afternoon wind. Winter and spring approaches require careful snowpack assessment; coordinate with the Eastern Sierra Avalanche Center before committing to steep terrain. Bring extra margin for wind and cold.
Nearby peaks in the Mammoth Lakes corridor include Mount Mammoth to the west and the Ritter Range peaks further north. Mount Baldwin's isolation and lower popularity make it a better choice for solitude than the more frequented volcanic summits around Mammoth Mountain. The corridor straddles Highway 395 and offers alternative access via Highway 203 from Mammoth town. Weather and avalanche conditions in the Eastern Sierra shift rapidly with elevation and exposure; check current reports before departing.
