North Maggie Mountain
Peak · 10,232 ft · Kings Canyon & Sequoia corridor
North Maggie Mountain is a 10,232-foot peak in the Kings Canyon and Sequoia corridor of California's Sierra Nevada. A seldom-visited summit in the high country, it sits colder and windier than lower valley floors.
Wind accelerates in the afternoon as thermal gradients strengthen; morning departures find calmer air. The 30-day average wind is 10 mph, but gusts reach 22 mph by mid-day. At 10,000 feet-plus elevation, temperatures average 30 degrees Fahrenheit and fluctuate sharply between sun and shadow.
Over the past 30 days, North Maggie Mountain averaged a NoGo Score of 36, with wind averaging 10 mph and temperatures holding near 30 degrees Fahrenheit. The week ahead shows variable conditions typical of spring transition in the high Sierra; expect afternoon winds to pick up. Plan early starts and watch avalanche forecasts closely, as snowpack is still present and destabilization risk peaks mid-day as solar radiation intensifies.

About North Maggie Mountain
North Maggie Mountain rises in the Kings Canyon and Sequoia corridor, a remote section of the Sierra Nevada east of the main crest. Access via Highway 180 from Fresno leads to the Kings Canyon trailhead region; from the east, Highway 395 and Highway 168 provide approach routes to the Inyo National Forest side. The peak sits in genuine high-country terrain, far from the Valley floor and away from the dense lodge infrastructure of the main tourist corridor. Base popularity is low, meaning crowds are sparse and solitude is typical. Winter and early spring approach requires avalanche training and constant snowpack assessment.
Conditions on North Maggie Mountain are shaped by exposure and altitude. The 30-day rolling average temperature of 30 degrees Fahrenheit reflects sustained cold; the annual range spans 17 degrees Fahrenheit minimum to 47 degrees Fahrenheit maximum, a compression typical of high-elevation peaks where diurnal swings matter more than seasonal extremes. Wind averages 10 mph over 30 days but peaks at 22 mph, often in afternoon hours as valley heating drives upslope flow. Crowding averages 2.0 on the NoGo scale, indicating solitude is nearly guaranteed. Late September and early October offer the most stable conditions and clearest access, while spring snowmelt and summer afternoon thunderstorms demand experience and timing.
North Maggie Mountain suits experienced mountaineers, ski mountaineers, and winter climbers with avalanche training. Summer scramblers can approach via snowless ridges in late season, but the peak demands route-finding, scramble skills, and weather judgment. Afternoon wind and temperature swings are the dominant planning constraints; head out early, summit by midday, and descend before thermal winds intensify. Parking is limited and trailheads are remote; plan for a long drive and self-sufficiency. Winter and spring ascents require beacons, probes, shovels, and current avalanche observations from the Eastern Sierra Avalanche Center.
Nearby peaks in the Kings Canyon and Sequoia corridor include Maggie Mountain (the higher southern twin) and Colosseum Mountain to the north. The Cathedral Range and Evolution Peaks lie across the main crest to the west, more accessible from Highway 120 but similarly demanding. North Maggie Mountain's low base popularity and remote position make it a better choice than crowded alternatives for those seeking solitude in active avalanche terrain; the trade-off is minimal trailhead infrastructure and a longer commute from major highways. Winter approaches from both east and west require current conditions reports and team experience.
