Cony Crags
Peak · 10,539 ft · Yosemite corridor
Cony Crags is a 10,539-foot peak in the Yosemite corridor of California's Sierra Nevada, set in alpine terrain with significant avalanche exposure. A high-elevation destination for experienced mountaineers.
Wind averages 9 mph across the month but gusts to 30 mph by afternoon; morning ascents are calmer. Temperature hovers near 27 degrees Fahrenheit on the 30-day average. Expect snowpack instability in spring; approach avalanche terrain with caution and route knowledge.
Over the last 30 days, Cony Crags has averaged a NoGo Score of 33, with wind averaging 9 mph and temperature at 27 degrees Fahrenheit. Conditions remain marginal through late spring as snowpack transitions and afternoon wind strengthens. The week ahead follows the typical seasonal pattern of marginal-to-poor conditions until stable melt consolidates the snowpack.

About Cony Crags
Cony Crags sits at the high end of the Yosemite corridor, accessed via Highway 120 through Tuolumne Meadows. The peak lies in true alpine terrain with significant avalanche-prone slopes on its approaches. Most parties approach from the Tioga Pass side via Tuolumne Meadows and established high-Sierra passes; the nearest trailheads are 7 to 9 miles distant. This is not a casual day hike; climbers must carry ice tools and crampons and understand snowpack mechanics. The nearest gateway towns (Lee Vining to the east, Groveland to the west) are 45 to 90 minutes away depending on season and Highway 120 closures.
Cony Crags sits in a zone where temperature averages 27 degrees Fahrenheit on the 30-day rolling window, staying well below freezing for much of the year. Wind averages 9 mph but regularly gusts to 30 mph by mid-afternoon, particularly in spring and early summer. Crowding remains minimal (3.0 on the rolling 30-day average) because the peak demands technical skill and is buried under snowpack for much of the year. Spring and early summer bring the highest human traffic but also peak avalanche hazard as warming consolidates the pack. Late autumn, before early snowfall locks in, offers the shortest window of relative snow stability and lowest avalanche risk, though this window often lasts only 2 to 4 weeks.
Cony Crags is designed for mountaineers with crevasse rescue training, avalanche awareness, and experience on steep snow and rock. Weekend warriors and peak-baggers without technical snow skills should not attempt this location. Experienced climbers plan ascents for early morning to avoid afternoon wind and to complete the descent before sun-softened snow becomes unstable. Parking at Tioga Pass and nearby Tuolumne Meadows trailheads fills quickly on weekends; arrive before dawn or plan a mid-week visit. Water is available only from snowmelt; carry a stove and fuel. Descent timing is critical; descending into afternoon wind and weakening snowpack compounds exposure and increases rockfall and slip risk.
Nearby alternatives at similar elevation include Cathedral Peak and Unicorn Peak, both accessible from Tuolumne Meadows with lower technical demand. Lyell Peak and Mount Conness offer comparable Sierra Nevada alpine experience with slightly easier approach and lower avalanche exposure. For climbers prioritizing technical challenge and isolation, Cony Crags rewards the commitment; for others, the Tuolumne Meadows cluster of peaks delivers comparable views with lower avalanche hazard and more flexible descent windows.
