Clarks Peak
Peak · 7,112 ft · North Sierra corridor
Clarks Peak is a 7,112-foot summit in the North Sierra corridor east of the main crest. Exposed ridge terrain above timberline, typically windier than protected valleys to the west.
Wind accelerates sharply above 6,500 feet as you gain the open ridgeline. The 30-day average wind of 13 mph masks afternoon gusts that exceed 25 mph regularly. Morning conditions are calmer; afternoon exposure increases both wind load and crowding.
The rolling 30-day average score of 35.0 reflects spring instability and variable snow. Temperatures average 39 degrees Fahrenheit; watch for rapid afternoon warming that destabilizes wet slabs in the upper drainage. The week ahead shows typical spring volatility with wind gusts to 27 mph on exposed terrain.

About Clarks Peak
Clarks Peak stands in the North Sierra, a high-elevation summit accessible via Highway 395 from Loyalton or via Highway 89 from the west. The peak sits above the headwaters of drainages that feed east toward the Honey Lake valley. Most ascents begin from trailheads on the western approach; drive times from Susanville are 45 minutes to an hour depending on road conditions. Parking is limited and unmanaged; early arrival is mandatory on weekends. The location sits within the SAC avalanche center, and avalanche terrain dominates the upper gullies and couloirs.
Clarks Peak's weather is shaped by its elevation and exposure to Pacific weather systems. The 30-day average temperature of 39 degrees Fahrenheit is typical for April; the range from 23 to 57 degrees across a year signals extreme seasonality. Winter snowpack lingers into May most years; the avalanche center issues advisories regularly through spring. Wind averages 13 mph across the rolling 30-day window but peaks at 27 mph during storm passage and afternoon thermal cycles. Crowding averages 5.0 on the metric scale; weekends see spikes tied to Highway 395 visibility and stable weather windows. Summer (July through September) brings lower snow hazard but afternoon thunderstorms. Fall offers the calmest conditions but shortest daylight.
Climbers and winter mountaineers are the primary users. Parties with avalanche training and beacon discipline pursue the snow gullies; the terrain demands route-finding and slope-angle assessment. Summer hikers use exposed ridgeline routes that avoid gullies entirely. Expect afternoon wind and plan accordingly; morning departures before 6 a.m. significantly reduce wind exposure. Snowpack instability and wet-slab hazard are critical from March through May; check the SAC advisory before committing. Parking fill-up drives visitors away by 8 a.m. on nice weekends.
Nearby peaks like Lassen Volcanic National Monument and the Castle Crags offer lower-elevation alternatives when Clarks Peak's avalanche hazard is elevated or wind exceeds 27 mph. For hikers seeking a less technical summit in the North Sierra, Modoc Plateau peaks to the north present gentler terrain but longer drive times from the valley. Clarks Peak rewards early, methodical preparation and is best suited to parties comfortable with exposure and avalanche terrain assessment.
