Mount Ina Coolbrith
Peak · 8,051 ft · North Sierra corridor
Mount Ina Coolbrith rises 8051 feet in California's North Sierra corridor, a high peak exposed to wind and afternoon instability. Early and calm mornings offer the best shot.
Wind dominates here. The 30-day average runs 13 mph with gusts to 25 mph, strongest mid-afternoon as air masses funnel off adjacent terrain. Morning calm windows close by 10 a.m. Temperature averages 43 degrees Fahrenheit; snowpack lingers into late spring, creating slab hazard on steep north aspects.
Over the last 30 days the average NoGo Score has held at 35, with wind the primary driver of poor conditions. Temperatures average 43 degrees, the 30-day average wind of 13 mph peaks to 25 mph regularly. The week ahead will show similar patterns; plan for stable early hours before midday thermals and pressure-driven gusts remake the mountain.

About Mount Ina Coolbrith
Mount Ina Coolbrith sits in the high North Sierra roughly 10 miles north of Highway 50, accessible from the Carson Pass corridor or via Highway 89 from the Tahoe basin. The peak is typically approached from trailheads on the west side near the Sierra Crest; nearest significant towns are South Lake Tahoe and Jackson, each 45 to 90 minutes away depending on route and season. This is avalanche terrain; the SAC avalanche center covers the region. Winter access is limited; snow often blocks highways and trailheads until late spring.
Spring conditions dominate the rolling 30-day and 90-day statistics. Average temperature of 43 degrees Fahrenheit and average wind of 13 mph with max gusts to 25 mph reflect the transition season; snowpack is present and unstable on steep slopes, particularly north-facing slabs. The yearly range spans 23 degrees minimum to 62 degrees maximum. Crowding averages low at 5 on the rolling 30-day window, reflecting remote access and variable snow. Conditions improve sharply in late summer when snowpack vanishes and wind typically eases.
This peak suits hikers and mountaineers with avalanche awareness and high-altitude cold-weather tolerance. Afternoons are to be avoided; wind and sun-cup snow make descent hazardous. Parking is limited; arrive before dawn. Experienced visitors plan for a full day of exposure, carrying extra layers and rations. Snowpack persists on north aspects well into summer; microspikes or crampons are standard into mid-season. The rolling 30-day NoGo Score of 35 reflects frequent wind and unpredictable snow consolidation.
The North Sierra corridor offers alternatives at lower elevations with faster access. Peaks in the Carson Pass zone and ridge lines east of Highway 88 share similar wind patterns but shorter approach times. For those specifically seeking alpine exposure with avalanche terrain challenge, Mount Ina Coolbrith is less crowded than destination peaks near Yosemite or the main Tahoe ridges, making it a practical choice for skilled parties planning deliberately around morning windows.
