Lee Lake
Lake · 10,797 ft · Mammoth Lakes corridor
Lee Lake sits at 10,797 feet in the Mammoth Lakes corridor of California's eastern Sierra Nevada. This glacially-sculpted alpine lake offers solitude and high-elevation access to remote backcountry terrain.
Lee Lake is exposed to wind funneling down from the high passes; the 30-day average wind runs 14 mph, with gusts exceeding 40 mph common by afternoon. Morning calm is reliable but brief. Avalanche terrain surrounds the approach; winter and spring snowpack stability demands constant attention.
Over the past 30 days, conditions have averaged a NoGo Score of 36 with temperatures near 23 degrees Fahrenheit and wind at 14 mph. The week ahead shows typical spring volatility at this elevation: expect wind to remain the dominant constraint, with crowding staying light. Check avalanche conditions and the 7-day wind forecast before committing to any winter or early-spring approach.

About Lee Lake
Lee Lake lies in the high Sierra east of the Mammoth Lakes town center, at 10,797 feet elevation in terrain drained by the Owens River watershed. Access is via Highway 395 to Mammoth Lakes, then local roads and trailheads branching into the high country. The lake sits on the margin between day-hike reach and backcountry ski or climbing access. Winter and spring approach requires route-finding across avalanche terrain; summer and early autumn offer more straightforward foot travel. The nearest services and supply points are in Mammoth Lakes village, roughly 10 to 15 driving minutes from the highway trailhead approach.
Lee Lake occupies a basin at the edge of high-altitude exposure. The 30-day average temperature of 23 degrees Fahrenheit reflects typical springtime conditions at 10,797 feet; the rolling 365-day minimum temperature of 8 degrees shows winter severity. Wind is the dominant weather driver. The 30-day average wind of 14 mph masks afternoon acceleration; maximum wind in the rolling 30-day window reached 43 mph. Crowds remain sparse year-round, with the 30-day average crowding score of 4 indicating very light use. Snowpack persists well into late spring; winter approach demands avalanche awareness and stable snowcover.
Lee Lake suits experienced high-altitude hikers, backcountry skiers, and mountaineers comfortable with exposure and avalanche terrain. Summer and early autumn visitors should plan for afternoon wind and rapidly changing conditions. Winter and spring visitors must carry avalanche safety gear, know how to read terrain, and monitor ESAC (Eastern Sierra Avalanche Center) forecasts before departure. Parking is limited at trailhead access points; arrive early on any calm-weather weekend. The lake itself offers no shelter from wind or weather; exposed camping is not recommended. Most visitors use Lee Lake as a way point to higher basins or climbing objectives rather than a terminus destination.
Nearby alternatives in the Mammoth corridor include lower-elevation lakes offering calmer conditions and better developed access; nearby peaks and passes attract the same user base as Lee Lake but offer different topographic wind patterns. For visitors seeking alpine exposure without full avalanche terrain commitment, middle-elevation lakes in the Mammoth basin provide comparable views with gentler approach. Lee Lake's defining value is its remoteness and the directness of access to high-Sierra backcountry; the trade-off is complexity, weather volatility, and avalanche risk that make it unsuitable for casual visitors.
