Disaster Peak
Peak · 10,016 ft · Yosemite corridor
Disaster Peak stands at 10,016 feet in the Yosemite corridor of the Sierra Nevada, a wind-exposed alpine summit above the Cathedral Range. Winter and spring approach demands avalanche awareness.
Wind accelerates across the peak's open ridgeline, especially in afternoon hours when thermal flow strengthens. The 30-day average wind of 9 mph masks gusts to 23 mph on unstable days. Early morning calm is the norm; avoid the peak after 11 a.m. on windy forecast days.
Over the last 30 days, Disaster Peak averaged a NoGo Score of 32, with temperatures holding around 32 degrees Fahrenheit and wind averaging 9 mph. The rolling 30-day crowding average is 3, indicating light use. Watch the week ahead for wind gusts and temperature swings typical of high-Sierra spring conditions. Snow and avalanche hazard persist through late spring; check the Sierra Avalanche Center forecast before ascent.

About Disaster Peak
Disaster Peak crowns the eastern flank of the Yosemite wilderness at 10,016 feet, accessible from the Highway 120 corridor via Cathedral Lakes trail and basin approach. The peak sits northeast of Tenaya Lake and south of the Cathedral Range proper. Summer and early fall are the primary climbing windows; winter and spring ascents require mountaineering skills and current avalanche terrain assessment. Drive time from Yosemite Valley is roughly 90 minutes via Highway 120 to the Cathedral Lakes trailhead; from the San Francisco Bay Area, expect 4 to 5 hours total. The closest resupply is Lee Vining (Highway 395, east side) or Tuolumne Meadows ranger station (Highway 120, westbound).
The peak's exposure and elevation generate predictable daily wind cycles. The 30-day average wind speed of 9 mph is deceptive; maximum gusts reach 23 mph, most common in afternoon hours as thermal currents cross the basin. Temperature averages 32 degrees Fahrenheit over the rolling 30-day window, reflecting the current spring transition; the 365-day minimum is 19 degrees (deep winter), maximum 48 degrees (early September). Crowding remains low year-round (30-day average 3), a reflection of the technical approach and exposed terrain. Late September through early October offers the most stable weather window, with calmer afternoons and lower avalanche risk than spring. Winter and early spring ascents are legitimate but require full alpine gear, rope skills, and willingness to turn back if conditions deteriorate.
Disaster Peak suits climbers and scramblers with high-Sierra experience. Solo ascents are common but unwise given exposure and the peak's distance from established trails. Day trips are feasible from the Cathedral Lakes trailhead in good conditions, but a bivouac in the basin allows safe pre-dawn starts and reduces afternoon wind exposure. Parties should plan for snow and ice through spring and early summer; a light ice axe and crampons are standard. The peak sits in avalanche terrain; slopes facing north and east hold unstable slabs during warm spells and rapid snowmelt. Check the Sierra Avalanche Center bulletin for the Cathedral Range zone before committing. Parking at the Cathedral Lakes trailhead fills by 9 a.m. on weekends and holidays; arrive early or consider a weekday approach.
The Cathedral Range and Tenaya Lake region offer adjacent objectives. Cathedral Peak itself (10,911 feet) lies one basin west and is a more popular scramble with comparable time commitment. Mount Florence and Eichorn Peak are accessible from the same drainage and allow flexible multi-summit itineraries. The Tioga Road (Highway 120) typically opens by late May; spring ascents require either approach from the west with significant snow travel or acceptance of very limited parking and unpredictable conditions. Tuolumne Meadows Wilderness Permit office (open summer only) is the primary permitting checkpoint for overnight trips in the Cathedral Range.
