Henry Peak
Peak · 9,327 ft · Yosemite corridor
Henry Peak stands at 9,327 feet in the Yosemite corridor of the Sierra Nevada, a high alpine summit exposed to afternoon wind funnels and spring snowpack instability.
Wind accelerates off the surrounding ridges by early afternoon, averaging 8 mph over the past 30 days but gusting to 19 mph in exposed sections. Morning hours are calmer. Snowpack dominates the approach through late spring; avalanche terrain requires careful route selection and stable conditions.
Over the past 30 days, Henry Peak averaged 32 degrees with a 30-day average wind of 8 mph and crowding at 3 out of 10. The week ahead tracks typical late-spring patterns: temperature climbing into the 40s during the day, wind picking up by midday, and snow consolidation changing stability daily. Plan around morning windows and check SAC avalanche forecasts before any winter or early-spring approach.

About Henry Peak
Henry Peak sits on the high-Sierra spine east of Yosemite Valley, accessible via Highway 120 from the west or Highway 395 from the east. The approach varies by season and route; winter and spring ascents typically start from the eastern side via High Sierra trailheads or from Tenaya Lake area on the western approach. Elevation at 9,327 feet places it firmly in the alpine zone, well above tree line, with exposure to the unobstructed wind patterns that rake the crest. The peak is least crowded compared to signature Yosemite summits like Half Dome or Cloud's Rest.
Conditions shift dramatically by season. Winter brings deep snowpack and avalanche hazard on all north and east-facing slopes; spring sees daily consolidation cycles and wet-slab risk as afternoon sun destabilizes the pack. Summer and early fall offer the window of lowest snow, though afternoon thunderstorms are routine and wind remains a constant factor above 9,000 feet. The 30-day average temperature of 32 degrees reflects early-season transitions; expect the range to widen from a 365-day low of 21 degrees in deep winter to highs near 48 degrees in mid-summer. Crowding stays light, averaging 3 out of 10, because the approach requires scrambling or technical climbing and winter conditions deter casual visitors.
Henry Peak suits climbers and experienced scramblers with winter mountaineering skills; casual hikers should target the neighboring 9,000-foot ridges with gentler terrain. The dominant planning factor is avalanche risk in winter and spring. Check SAC advisories before any approach between December and May. Summer parties should summit by early afternoon to avoid thunderstorm exposure; descent in lightning is a real hazard. Wind gusts to 19 mph are routine on the exposed crest, so insulating layers and windproof outerwear are mandatory even on warm-looking days.
Nearby alternatives include Cathedral Range peaks to the west (accessible from Highway 120), which offer similar elevation and exposure but more defined routes. Tenaya Lake, 3 to 4 miles north, provides a lower-elevation option for weather observation and turnback points. The eastern approaches via the Sierra crest (Highway 395 access) share identical avalanche terrain and wind patterns but tend to be drier in early season. All routes in this corridor sit above the valley microclimate and experience wind regimes distinct from protected passes or lakeside zones to the south.
