The Sisters
Peak · 10,150 ft · Lake Tahoe corridor
The Sisters, a 10,150-foot peak in the Lake Tahoe Sierra, commands the ridge between Carson Pass and the high country. Winter and spring access demands avalanche awareness and stable snowpack.
Wind accelerates on the exposed ridge, gusting harder in afternoon hours as thermal circulation builds from the valley floor. Snow-fed terrain holds powder early season but transitions to wind slab and sun crust by late morning. Crowds stay low year-round relative to better-known summits.
Over the past 30 days, The Sisters averaged a NoGo Score of 41, with winds holding at 8 mph and temperatures near freezing. The week ahead will test avalanche stability and wind patterns; check the Carson Range forecast before committing to higher elevations. Late April snowpack is volatile: aspect and recent thermal input matter more than raw depth.

About The Sisters
The Sisters sits on the main crest of the Carson Range, straddling the boundary between Alpine County and the Mokelumne Wilderness. The peak is most commonly accessed from Carson Pass on Highway 88, roughly 45 minutes east of Jackson and 90 minutes south of Lake Tahoe. Winter and spring routes contour into the pass cirque and climb via snow gullies; summer ascents follow broken granite and talus. The peak is less trafficked than nearby Meiss Cone or Red Lake Peak, making it a choice for climbers seeking solitude in the high Sierra.
Elevation and exposure define The Sisters' character. At just over 10,000 feet, the peak sits above treeline in an area where winter can persist into late June. The 30-day average wind of 8 mph masks afternoon gusts; spring storms push peaks to 24 mph. Temperatures average 30 degrees Fahrenheit across the rolling month, swinging between 15 and 44 degrees across the calendar year. Snowpack stability is the controlling variable from December through May; the SAC avalanche center covers this zone, and consulting their outlook is mandatory before any winter or spring ascent. Crowds remain minimal, averaging 1.0 on the crowding scale.
The Sisters suits climbers with avalanche training, winter mountaineers, and peak-baggers tackling the Carson Range high points. Late season (late June through September) sees calm mornings and dry conditions; wind still builds by afternoon, but overnight frosts harden any remaining snow. Approach parking is limited; arrive at Carson Pass before dawn on weekends. Spring and early summer are best for climbers comfortable reading snowpack and managing wind exposure. Avoid the peak if storm systems are active or if the avalanche forecast is above 'Considerable' in the immediate vicinity.
Nearby alternatives include Red Lake Peak (10,383 ft) to the south and Meiss Cone (10,160 ft) to the north. Red Lake is more popular but exposes you to higher wind loading on the exposed ridge. Meiss Cone offers a slightly lower-angle approach and sits in similar terrain but commands less ridge exposure. Visitors pairing multiple summits should plan for deteriorating afternoon conditions; cache water and turn around by early afternoon if wind or clouds develop.
