Hiram Peak
Peak · 9,796 ft · Yosemite corridor
Hiram Peak is a 9,796 ft summit in the Yosemite corridor of California's Sierra Nevada, sitting above the glacial lakes and granite slopes of the high country. Wind-swept and exposed, it rewards calm mornings.
Wind accelerates across the open ridgeline by mid-afternoon, typically averaging 11 mph over the last month with gusts reaching 29 mph. Morning hours are markedly calmer. Temperature hovers near 29 degrees over rolling 30 days; expect hard snow through spring. Exposed terrain means no shelter once you leave the treeline.
Over the last 30 days, Hiram Peak averaged a NoGo Score of 33, with wind averaging 11 mph and temperatures near 29 degrees. The week ahead will show how spring melt and afternoon thermals reshape climbing conditions. Watch the trend grid for wind spikes and crowding surges tied to Highway 120 openings and weekend traffic. Winter-to-spring transition means avalanche terrain remains live; probe and assess snowpack before committing to the high passes.

About Hiram Peak
Hiram Peak stands at 9,796 feet on the eastern rim of the Yosemite corridor, positioned above the cluster of alpine lakes and granite benches that characterize the high Sierra watershed. Access is via Highway 120 (Tioga Road) east of Yosemite Valley. The peak sits in the Sierra Nevada's driest rain shadow, on terrain managed by the U.S. Forest Service and the National Park Service. Gateway towns include Lee Vining and Tuolumne Meadows; most approach routes funnel through Tioga Pass or Mammoth Lakes. The summit commands views across the Mono Basin and the Cathedral Range; the peak is a destination for experienced alpinists and scramblers seeking high, exposed terrain with minimal crowds.
Conditions at Hiram Peak are governed by elevation, exposure, and its position astride the Sierra crest. Over the rolling 30-day window, average temperature sits at 29 degrees Fahrenheit; the year-round minimum drops to 16 degrees, maximum climbs to 45 degrees. Average wind runs 11 mph, but gusts spike to 29 mph on exposed ridges. The 30-day rolling average crowding is 3 (light), reflecting low baseline popularity and harsh conditions that deter casual day-hikers. Late spring through early fall offers the narrowest weather windows; winter and early spring demand avalanche awareness and microspike or axe competence. Afternoon thermal winds are reliable; mornings before 10 a.m. are typically calmer. Snowpack persists well into summer at this elevation and aspect.
Hiram Peak suits mountaineers, peak-baggers, and off-trail scramblers comfortable with steep, rocky, snow-covered terrain and self-rescue scenarios. No marked trail reaches the summit; approach involves cross-country navigation, talus, and possibly snow climbing depending on season. Parking near the trailhead can fill quickly on weekends, especially after Highway 120 opens for the season. Experienced visitors plan ascents for early morning windows to avoid afternoon wind and to descend before conditions deteriorate. Avalanche terrain is present on approach slopes; check the Sierra Avalanche Center forecast before any spring climb. Water sources are scarce on the peak itself; approach-route creeks are snowmelt-dependent and often absent by late summer.
Nearby high peaks in the corridor include Cathedral Peak, Mammoth Mountain, and the metamorphic peaks ringing Yosemite's eastern gate. Hiram Peak is notably more exposed and less traveled than Cathedral Peak but offers similar alpine-climbing challenges. The Cathedral Range to the west offers snow climbing and glacier access in early summer; the White Mountains to the east are drier and more desert-like. Winter ascents of Hiram Peak are uncommon due to avalanche exposure and extreme cold; late summer and early fall offer the most stable snow conditions and reliable access. Basecamp logistics favor the Tuolumne Meadows region or the Mammoth Lakes approach, both subject to early-season closures tied to Highway 120 and Highway 203 openings.
