Epidote Peak
Peak · 10,958 ft · Yosemite corridor
Epidote Peak is a 10,958-foot summit in the Yosemite corridor of the Sierra Nevada, accessed from the eastern High Country. Sits exposed to afternoon wind funneling off adjacent drainage systems.
Typically windy from mid-afternoon onward; the 30-day average wind is 15 mph, with gusts to 33 mph common in spring. Morning calm is the exception. Avalanche terrain dominates the approach; snowpack stability dictates safe crossing windows.
Over the last 30 days, Epidote Peak has averaged a NoGo Score of 31, with temperatures around 25 degrees Fahrenheit and winds holding to 15 mph. The week ahead will likely track similar patterns; plan morning ascents before wind builds, and confirm avalanche bulletin conditions before travel. Crowding remains minimal at a 30-day average of 3.

About Epidote Peak
Epidote Peak sits at 10,958 feet in the high Sierra, roughly 8 miles north of Tioga Pass along the eastern rim of the Yosemite backcountry. Access requires a 4x4 road or high-clearance vehicle from the Highway 120 corridor, or a longer approach from the Mono Basin side via BLM routes. The peak is rarely crowded; most visitors approach via ski mountaineering in winter or scrambling in summer from the Tioga-Mono divide. The nearest gateway is Lee Vining on the eastern flank; Yosemite Valley lies 50 miles to the west.
Spring and early summer bring the highest avalanche hazard; persistent snow slabs form on north and northeast-facing slopes above 10,000 feet. Wind averages 15 mph over the past 30 days but peaks at 33 mph in afternoon hours, making exposed ridges untenable after noon. Temperatures range from a 365-day low of 11 degrees Fahrenheit to summer highs near 40 degrees. Late summer and fall offer the best travel window, with stable snow coverage vanishing by September and wind speeds more manageable. Winter closure of Tioga Pass (Highway 120) eliminates casual vehicle access from November through late May.
Epidote Peak suits experienced ski mountaineers and high-altitude scrambling climbers who can recognize and navigate avalanche terrain. Summer visitors should expect loose talus, minimal water sources, and exposure to afternoon winds that can exceed 30 mph. The peak offers no maintained trail, water caches, or refuge; parties must self-rescue. Most ascents take a single day from the trailhead. Parking is informal; arrive early in July and August to secure a turnout along the approach road.
Epidote Peak pairs naturally with neighboring peaks in the White Mountains (Boundary Peak, Montrose Peak) for a multi-peak traverse. The isolated eastern Sierra location makes it a committing objective; plan for wind, avalanche hazard assessment, and self-sufficiency. Compared to the more crowded Yosemite Valley backcountry, this peak offers solitude and higher altitude exposure, but demands stronger weather reading and terrain judgment.
