Dark Side Dome
Peak · 8,754 ft · Yosemite corridor
Dark Side Dome peaks at 8,754 feet in Yosemite's high Sierra corridor. A wind-exposed alpine summit with avalanche terrain, it demands stable snowpack and calm morning windows.
Wind accelerates sharply by mid-afternoon, often funneling across the exposed ridge. The 30-day average wind of 9 mph masks afternoon gusts reaching 30 mph. Cold lingers even in late spring; morning ascents are safer and calmer than afternoon approaches.
The 30-day average NoGo Score of 33 reflects persistent wind exposure and seasonal snowpack instability. Over the past month, conditions have ranged from a low of 5 to a high of 50, with average temperatures near 30 degrees Fahrenheit. The week ahead shows typical spring volatility; plan for calm mornings and expect afternoon deterioration.

About Dark Side Dome
Dark Side Dome sits in the high-elevation Yosemite corridor at 8,754 feet, accessible from Highway 120 via Tenaya Lake or from the Tuolumne Meadows area. The peak's north aspect and exposed ridgeline make it a winter and spring destination for ski mountaineers and experienced winter climbers. Access requires passage through the Yosemite high country; Highway 120 closes seasonally, limiting approach windows. The nearest reliable services are in Lee Vining or Tuolumne Meadows.
Dark Side Dome sits in active avalanche terrain; the north and west faces hold snow accumulation well into spring. The 30-day average temperature of 30 degrees Fahrenheit indicates sustained winter conditions despite late-season dates. Wind averages 9 mph over rolling 30 days but peaks at 30 mph, creating both avalanche loading risk and cornicing hazard on the summit ridge. Crowding remains minimal (3.0 on the rolling 30-day average), typical of exposed high-altitude peaks. Late spring and early summer see rapid snowpack loss; by mid-summer the peak transitions to a scree scramble with minimal snow.
Dark Side Dome suits experienced winter mountaineers comfortable with avalanche assessment and self-rescue. Casual peak-baggers should wait for late summer when snow stability ceases to be the controlling factor. Wind exposure demands calm-morning starts; afternoon ascents invite slabbing risk from wind-transported snow and exposure to sudden gusts. Parking at the trailhead fills quickly on weekends during the brief spring window when Highway 120 is open and snow remains trackable. Bring avalanche beacon, probe, and shovel; beacon use is not optional on the approach slopes.
Nearby alternatives include Cathedral Peak and Tenaya Peak, both accessible from similar Highway 120 approaches but lower in elevation and less wind-prone. The Matthes Lake basin offers a less technical alternative for those seeking high-Sierra views without sustained avalanche terrain. Mono Basin peaks east of the Sierra crest see slightly less winter precipitation but deliver similar wind exposure; Dark Side Dome's proximity to Tenaya Lake makes it a natural pairing with lower-elevation alpine lake touring.
