Chowchilla Mountain
Peak · 6,906 ft · Yosemite corridor
Chowchilla Mountain is a 6906-foot peak in the Yosemite corridor's high Sierra. Wind-exposed and sparsely visited, it rewards clear mornings and penalizes afternoon approaches.
Chowchilla Mountain catches wind funneling off adjacent drainages by mid-afternoon. The 30-day average wind is 7 mph, but gusts reach 17 mph routinely. Morning calm gives way to steady flow by 2 p.m. Exposed ridges amplify wind effect; tree shelter is minimal above 6500 feet.
Over the last 30 days, Chowchilla Mountain averaged a NoGo Score of 31, with temperatures at 55 degrees and an average wind of 7 mph. The week ahead shows typical spring variability; morning windows remain most reliable, while afternoon wind patterns persist. Snowpack lingers in shaded gullies; probe before committing to sustained steep terrain.

About Chowchilla Mountain
Chowchilla Mountain sits in the high Sierra northeast of Yosemite Valley, accessible via Highway 120 from the west or Highway 395 from the east. The peak is a secondary summit on the ridgeline separating the Merced and Tuolumne drainages. Most approaches begin from high-elevation trailheads on or near the Tioga Road corridor. Base popularity is low (0.2); the peak sees foot traffic only from Pacific Crest Trail users and backcountry peakbaggers. Winter access is weather-dependent; Highway 120 closes seasonally and chains are required in shoulder months.
Chowchilla Mountain experiences compressed seasonal windows compared to lower elevations in the corridor. The 30-day average temperature is 55 degrees Fahrenheit; the 365-day range spans 43 to 75 degrees. Spring and early summer bring the most stable conditions, though afternoon wind increases as solar heating accelerates. Late September through October delivers the lowest crowding (average 3.0 persons per day in the 30-day window) and reliable weather windows. Winter snowpack persists through May on north-facing slopes; avalanche terrain is present and requires assessment of recent precipitation and wind-slab formation.
Chowchilla Mountain suits experienced peakbaggers, PCT thru-hikers, and alpine scramamblers comfortable with exposure and route-finding. The summit offers no water or shelter. Visitors typically plan one-day ascents from nearby trailheads or multi-day backpack routes down the adjacent ridgelines. Wind becomes a dominant planning factor in afternoon windows; the 30-day maximum wind of 17 mph occurs regularly by 3 p.m. Backcountry camping near the peak is sparse and exposed; most visitors descend before nightfall. Avalanche awareness is essential on the north and west-facing approaches; consult the Sacramento Avalanche Center for current snowpack stability before winter and spring travel.
Chowchilla Mountain is often paired with traverses to neighboring high peaks along the Sierra crest. The isolation and sparse crowds make it an alternative to more trafficked summits in the Yosemite corridor. Visitors comparing conditions should note that Chowchilla Mountain's rolling 30-day NoGo Score (31) is higher than protected lake basins but lower than fully exposed ridge systems farther east. Access via Highway 120 connects it to the broader Tioga Road corridor; Highway 395 offers a longer approach from the east. Plan ascents during late September or early October for the most reliable combination of passable terrain, stable weather, and minimal crowding.
