Prosser Hill
Peak · 7,155 ft · Lake Tahoe corridor
Prosser Hill is a 7,155-foot peak in the Lake Tahoe corridor's Sierra Nevada. Moderate elevation and proximity to Highway 50 make it accessible; avalanche terrain demands winter caution.
Wind rises predictably by mid-afternoon, funneling off the lake surface. Morning hours are calmer and notably warmer relative to the sustained 8 mph 30-day average. Snow persists into late spring; assess slope stability before committing to north-facing drainages.
Over the last 30 days, Prosser Hill has averaged 8 mph wind and a NoGo Score of 42, with peaks to 20 mph in afternoon hours. Temperatures have held near 41 degrees Fahrenheit. The week ahead shows typical spring patterns: stable mornings with rising wind by afternoon. Plan accordingly if you're approaching avalanche terrain.

About Prosser Hill
Prosser Hill sits at 7,155 feet on the eastern shoulder of the Lake Tahoe basin, roughly 10 miles southeast of Tahoe City via Highway 89 and sideroads into the Tahoe National Forest. The peak anchors a series of ridges and draws above the Prosser Creek drainage, which feeds northbound into Stampede Reservoir. Primary access routes approach from the west via Forest Service roads or from Highway 50 corridors to the south. The location is a low-popularity destination; crowds are sparse compared to nearby Echo Lake or Pyramid Peak, making it a viable option for visitors seeking solitude during peak season.
Spring and early summer bring rapid snowpack transition at this elevation. The 30-day average temperature of 41 degrees Fahrenheit, combined with typical wind of 8 mph, signals a shoulder season where morning stability gives way to afternoon wind loading and wet-slab risk on steep slopes. Winter lingers through April; approach any snow-filled gully with avalanche awareness. By July, snow retreats to high couloirs and permanent snowfields. Late September to mid-October offers the most stable conditions: moderate temperatures, low wind, and clear skies. Summer afternoons see consistent wind and occasional smoke from Sierra fires; mornings are optimal. Winter access requires snowshoe or ski and strict avalanche forecasting protocol.
Hikers and peak baggers use Prosser Hill as a moderate-effort summit; climbers occasionally approach it for snow and ice practice in winter. The peak suits parties with solid route-finding skills and patience for brush and talus. No maintained trail reaches the summit; navigation relies on topographic map and compass or GPS. Experienced winter mountaineers treating it as an avalanche-assessment opportunity do so only after consulting the Sacramento Avalanche Center forecast. Parking is limited to pullouts along Forest Service roads; arrive early on weekends. A headlamp is essential for any pre-dawn start to avoid afternoon wind.
