Mount Irvine
Peak · 13,851 ft · Eastern Sierra corridor
Mount Irvine is a 13,851-foot peak in California's Eastern Sierra corridor. High-elevation, wind-exposed terrain above glaciated drainages; typically calmer in early morning hours.
Wind averages 12 mph over the last month, with gusts reaching 43 mph in afternoon funnels. Cold dominates; the rolling 30-day average sits at 16 degrees Fahrenheit. Mornings offer the calmest window before midday thermals drive wind upslope.
The last 30 days averaged a NoGo Score of 37 with temperatures holding at 16 degrees and wind at 12 mph; peaks topped 43 mph on exposed ridges. The week ahead will track similar patterns. Watch for afternoon wind surge typical of high-elevation Eastern Sierra peaks in spring; avalanche terrain remains relevant until late-season consolidation.

About Mount Irvine
Mount Irvine sits at 13,851 feet in the Eastern Sierra corridor, a peak accessible via approaches from the Inyo National Forest. The peak stands above glaciated terrain and granite drainage systems typical of the high Sierra backcountry east of the central crest. Primary access runs through Highway 395, the spine of the eastern slope, with gateway towns offering supplies and lodging. Spring conditions bring lingering snowpack and avalanche hazard; the rolling 365-day maximum wind of 43 mph reflects the exposure common to peaks above 13,500 feet in this corridor.
Temperature patterns swing dramatically with season. The rolling 365-day record shows a low of negative 2 degrees and a high of 36 degrees; the last 30 days averaged 16 degrees, indicating winter or early spring conditions persist. Wind shows seasonal consistency: the 30-day average of 12 mph is identical to the 90-day and 365-day averages, meaning Mount Irvine faces sustained wind pressure year-round. Crowding remains minimal at an average of 2 on the rolling 30-day window, reflecting the peak's technical character and high-elevation demand. Most visitors come during the brief window of consolidated snow and stable weather in late summer and early fall.
Mount Irvine suits experienced alpinists and winter mountaineers comfortable with avalanche terrain and sustained cold. The 30-day NoGo Score averaged 37 with a low of 9 and high of 65, indicating highly variable conditions day to day. Morning ascents exploit the calmest window before afternoon wind develops; afternoon descents on steep snow carry slough and slab hazard. Winter and early spring approaches demand current avalanche observations from ESAC (Eastern Sierra Avalanche Center); snowpack stability is not guaranteed even on moderate-looking slopes. A base popularity of 0.2 reflects the peak's isolation and technical barrier.
Nearby peaks in the Eastern Sierra corridor offer similar exposure and elevation. The sustained wind of 12 mph average and rolling maximum of 43 mph are typical of the corridor's highest terrain. Climbers seeking slightly lower-elevation alternatives or more forgiving approach terrain will find options a few miles north or south along the crest. The peak's location in avalanche terrain means that spring and winter ascents require avalanche beacon, probe, and shovel; summer ascents rely on rock scrambling and require familiarity with high-altitude exposure and objective hazard assessment.
