Eichorn Pinnacle
Peak · 10,718 ft · Yosemite corridor
Eichorn Pinnacle rises to 10,718 feet in the Yosemite high Sierra, offering direct exposure to afternoon wind and reliable snow through spring. A serious alpine objective with avalanche terrain.
Wind accelerates from calm mornings to sustained afternoon gusts. The 30-day average wind of 12 mph masks afternoon surges to 33 mph that pin down the peak by mid-day. Temperatures hold near freezing even in daylight. Crowds are minimal; access is a real commitment.
Over the last 30 days, Eichorn Pinnacle averaged a NoGo Score of 32, with wind peaking at 33 mph and temperatures averaging 24 degrees Fahrenheit. Morning windows are your only reliable tactical advantage. The week ahead reflects continued high-elevation volatility; plan for afternoon wind lockout and stable snow only on calm days.

About Eichorn Pinnacle
Eichorn Pinnacle stands on the high crest of the Sierra Nevada east of Yosemite Valley, accessible via Highway 120 from Lee Vining or Highway 395. The approach is a serious backcountry ski or mountaineering route; there is no trailhead parking or summer road access. Winter and spring are the only realistic seasons. Visitors typically stage from the Lee Vining area or drive over Tioga Pass (Highway 120) when open, usually mid-May onward. The peak sits in avalanche terrain mapped by the Sierra Avalanche Center; unstable snowpack is a constant consideration until late spring.
The 30-day average temperature of 24 degrees and rolling wind average of 12 mph understate the daily rhythm. Mornings are often calm or nearly calm, with temperature inversions trapping cold air. By noon, wind rises predictably from the east and southeast, funneling off the desert floor and climbing the lee side. The 30-day maximum wind of 33 mph is typical for afternoon hours. Crowding averages just 3 out of 10, reflecting the technical commitment required and short season. Late April and May see the most stable conditions; June and July bring afternoon thunderstorms and rockfall risk.
This peak is for experienced mountaineers and ski tourers with avalanche training and awareness. The typical user is self-reliant, carries a beacon and probe, and knows how to read snowpack stability. Park in Lee Vining or at the Tioga Pass resort area; Highway 120 closure dates define the season. Expect firm corn snow in afternoon hours on stable days; wet-slab danger rises in May and June. Most parties go for the calm morning window, descend before wind peaks, and avoid the peak entirely if the 30-day average score exceeds 40.
Nearby Mount Dana (13,053 ft) is a higher, more exposed alternative on the same crest, with similar avalanche terrain. Mount Gibbs and Mount Warren offer lower, less committing high-Sierra ski options. Within Yosemite proper, Cathedral Range peaks to the west have longer approach seasons but steeper crowds once Highway 120 opens. Eichorn Pinnacle rewards solitude and early starts; it punishes afternoon delays and unstable snowpack.
