Peak · 11,095 ft · Yosemite corridor
Ink Rocks South is an 11,095-foot peak in the Yosemite corridor of California's Sierra Nevada. Exposed and windswept, it demands careful timing and avalanche awareness.
Wind drives conditions here. The 30-day average is 14 mph, with gusts routinely hitting 41 mph. Morning windows close by mid-day as thermal winds build off the surrounding terrain. Snowpack instability is a year-round threat; check SAC avalanche forecasts before travel.
Over the last 30 days, Ink Rocks South has averaged a NoGo Score of 32 with temperatures around 22 degrees and wind averaging 14 mph. The week ahead will likely track near these averages. Wind spikes remain the primary limiting factor for safe access. Cold and wind combine to raise avalanche hazard in spring; timing your climb for stable snowpack is critical.

About Ink Rocks South
Ink Rocks South sits at 11,095 feet in the high Sierra above the Yosemite corridor. Access runs via Highway 120 from the west or Highway 395 from the east; gateway towns include Lee Vining and Tuolumne Meadows. The peak itself is exposed alpine terrain with significant avalanche exposure on its flanks. Winter and spring ascents require avalanche terrain awareness and current SAC forecasts. Summer approach is faster and safer, but the window is short; Highway 120 does not reliably open until late spring.
This peak operates in the extreme cold-wind regime. The 30-day average temperature is 22 degrees Fahrenheit; the 365-day range spans 6 to 35 degrees. Wind is relentless. The 30-day average is 14 mph with maximum gusts of 41 mph recorded across the full year. Crowds remain minimal year-round due to elevation, access difficulty, and avalanche hazard. Expect single-digit to low-teen visitor counts even on sunny weekends. Early season (spring) brings deeper snow and higher instability; late summer offers the most stable conditions but also the shortest weather windows.
Ink Rocks South is a destination for experienced mountaineers and ski mountaineers with avalanche training. Summer climbers should plan for exposed rock travel above treeline and rapidly changing weather. Spring ascents demand advanced avalanche skills, knowledge of snowpack structure, and commitment to conservative decision-making. Parking near the trailhead fills quickly on rare good-weather weekends. Afternoon wind is relentless; all ascents should start before dawn and plan descent by early afternoon. Smoke from Sierra wildfires can close sightlines in late summer and early fall.
Nearby alternatives in the corridor include Mammoth Peak and other summits accessible from Highway 395. The Yosemite high country offers less extreme terrain and more protected basins for climbers seeking similar elevation without the exposure. Ink Rocks South is not a training ground; it is a commitment climb suited only to parties with the skills and conditions to match its hazard.
