The Mounds
Peak · 4,980 ft · North Sierra corridor
The Mounds is a 4980-foot peak in the North Sierra corridor, sitting between the high-elevation basins of the northern Sierra Nevada. Typically calmer than exposed ridgelines to the east, it draws winter and shoulder-season visitors seeking moderate alpine terrain.
Wind picks up sharply after mid-morning, funneling off adjacent drainages and open slopes. Cold soaks in morning stillness; afternoon thermals and pressure changes drive sustained gusts. Snow and rime coat the upper reaches into late spring. Head here at first light if you're sensitive to wind.
Over the past 30 days, The Mounds has averaged 9 mph wind and 44 degrees Fahrenheit, with a NoGo Score of 35, indicating moderate stability and moderate crowding. The week ahead tracks typical spring patterns for the North Sierra: morning windows narrow as afternoon thermals strengthen, and late-season snow consolidates faster as sun angle steepens. Watch for rapid freeze-thaw cycling on the descent.

About The Mounds
The Mounds sits at 4980 feet in the North Sierra corridor, a compact alpine peak with reliable snow through spring and moderate exposure. Access is typically from the western foothills via Highway 89 or Highway 395, with the nearest supply towns at Truckee and Chester. Winter approach requires a snowmobile or skintrack; summer and shoulder-season entry is on foot or mountain bike from trailheads on the north and west flanks. The location sits in the SAC (Sacramento) avalanche zone; terrain includes runnable gullies and boot-pack traverses prone to slough and wind slab in the days after storms.
The 30-day average temperature of 44 degrees Fahrenheit and wind of 9 mph reflect The Mounds' typical spring profile: cold predawn temperatures that climb to freezing or just above by late afternoon, with a sharp wind step around 10 a.m. as pressure systems migrate eastward. Winter snow depth peaks in March and April; by late April consolidation accelerates and wind crust forms nightly. The rolling 30-day NoGo Score of 35 reflects frequent morning windows closed by wind and afternoon instability. Crowding averages 5, low to moderate; traffic clusters around weekends and holiday periods, but midweek solitude is reliable.
The Mounds suits winter and spring ski tourers, snowmobilers, and peak baggers willing to travel in marginal conditions. Experienced visitors plan around the predictable afternoon wind step and schedule descents before 2 p.m. to avoid wind slab and whiteout. Avalanche awareness is critical; the peak's gullies and lee slopes trap wind slab, and spring corn cycles create hard crust by midday. Park early; trailhead lots fill by 8 a.m. on weekends. Bring a shovel and probe, check the SAC advisory daily, and avoid travel the day after storms when remote triggering risk peaks.
Nearby alternatives include steeper couloir terrain on Sierra Buttes and Castle Peak to the north, both requiring more technical approach and carrying higher avalanche exposure. South, the Lassen Peak region offers gentler alpine walking but sits in a drier rain-shadow zone. The Mounds occupies a middle ground: shorter approach than Castle Peak, longer season than Lassen, and narrower stability margin than either. Pair a visit with Highway 89 passes (Donner, Carson) or the Feather River drainage for a multiday North Sierra trip.
