Gregory's Monument
Peak · 13,958 ft · Eastern Sierra corridor
Gregory's Monument is a 13,958-foot peak in the Eastern Sierra's high country, accessible from the Inyo National Forest. A remote alpine summit with significant avalanche terrain and exposure to sustained westerly wind.
Wind dominates the site. The 30-day average of 15 mph climbs to 42 mph gusts in afternoon hours; ridges funnel flow off the Sierra crest. Morning hours before 10 a.m. are noticeably calmer. Winter and early spring snowpack introduces slab and cornicing risk on north and east aspects.
Over the past month, Gregory's Monument averaged 15 mph wind and 22 degrees Fahrenheit, with a low NoGo Score of 8 and peak wind gusts of 42 mph. The week ahead continues this pattern of variable conditions; plan ascents for early morning windows and check avalanche forecasts before any snow season approach. Crowding remains minimal throughout the rolling 365-day window.

About Gregory's Monument
Gregory's Monument sits on the crest of the Sierra Nevada at 13,958 feet, straddling the Inyo National Forest boundary in the Eastern Sierra corridor of California. Access is primarily from the east via Highway 395 near Big Pine or Independence. The peak lacks a maintained trail; approach routes ascend via talus and scree from nearby lake basins or ridge traverses. The drive from Highway 395 to trailheads takes 45 minutes to over an hour depending on road conditions and parking area. Winter access is severely limited by snow and road closure; summer and early autumn are the primary windows for foot traffic.
Gregory's Monument experiences extreme alpine weather typical of Sierra crests above 13,500 feet. The 30-day average wind of 15 mph regularly exceeds 40 mph in the afternoons, particularly between 2 p.m. and 6 p.m. Temperatures average 22 degrees Fahrenheit in the rolling month measured, with the 365-day minimum dropping to 4 degrees and maximum reaching 35 degrees. Morning hours before 10 a.m. see the calmest conditions. Crowds are minimal year-round; the peak's remote access and avalanche terrain keep visitor numbers low. Late spring through early autumn offer the longest snow-free windows, though rockfall and unstable talus slopes persist.
Gregory's Monument suits experienced climbers and mountaineers comfortable with steep talus, exposure, and self-rescue. The summit offers panoramic views of the Inyo Crags, Mount Inyo, and the Sierra crest. Visitors should plan for morning-only ascents to avoid afternoon wind; allow eight to twelve hours round trip from base camps. Avalanche awareness is mandatory during winter and spring; consult the Sequoia Kings Canyon and Inyo National Forest avalanche forecast before travel. Carry a map and compass or GPS; cell service is unreliable. Water is scarce; plan for cache or pack extra. The peak's isolation and sustained wind make it unsuitable for casual day hikers or families.
Nearby alternatives include Mount Inyo at 13,661 feet and Striped Mountain at 13,741 feet, both offering similar alpine exposure with slightly lower elevations. The Inyo Crags to the south feature scrambling and rock climbing on granite. Hikers seeking less technical Eastern Sierra summits may prefer Mount Williamson or Mount Tyndall via the Whitney Portal corridor. Gregory's Monument's primary appeal lies in its remoteness and lack of maintained infrastructure; solitude is the defining characteristic.
