Mammoth Mountain snow report
Mammoth Mountain
Mammoth Mountain is a top ski resort in the United States located in California's Sierra Nevada Mountains. The resort boasts over 3,500 acres of skiable terrain, beautiful scenery, and a lengthy ski season. The best trails are the black diamond runs, such as the Paranoid Flats, which offer challenging terrain for advanced skiers. An interesting fact about Mammoth Mountain is that it is a volcano, and its last eruption was about 57,000 years ago. For beginner skiers, we recommend the gentle slopes of Little Eagle, which offer a great introduction to skiing. For an apres-ski drink, head to the Mammoth Brewing Company, which offers a range of locally brewed beers and delicious bites.
Terrain mix: Mammoth Mountain, located in the Eastern Sierra region of California, is part of the Sierra Nevada mountain range. The resort sits on the slopes of Mammoth Mountain itself, which is a lava dome complex that is part of the Long Valley Caldera. The mountain has an elevation of 11,053 feet and offers over 3,500 acres of skiable terrain.
Other nearby mountain ranges that can be seen from Mammoth Mountain include the White Mountains to the east and the Inyo Mountains to the southeast. These ranges add to the scenic beauty of the area and provide a stunning backdrop for skiing and snowboarding at the resort.

Mountain & avalanche safety
- Know before you go
- Check today's avalanche bulletin from the regional avalanche center before any off-piste / side-country / backcountry travel. Conditions can shift dramatically between morning and afternoon on storm days.
- Carry the gear, know how to use it
- Beacon, shovel, probe. Practice companion rescue on a calm day, not during a real burial.
- Mind the weather window
- Heavy snow + wind builds wind slabs at ridgelines. The day after a storm is often the riskiest in the backcountry, even if the resort itself is open.
- Respect closed terrain
- Ropes are there for a reason. Even in-bounds, ducking a closure can trigger a slide that catches you and others below.

About Mammoth Mountain
Where does the snow data for Mammoth Mountain come from?
Snowpack, SWE, 24-hour snowfall, and air temperature come from the nearest USDA NRCS SNOTEL station. Forecast comes from the National Weather Service / yr.no feed that Snoflo's iOS app uses.
How often is the snow report updated?
Snowpack and SNOTEL data are updated continuously by NRCS (typically hourly). The 15-day weather forecast is refreshed throughout the day. Snoflo caches and renders the most recent observation -- look for the "as of" timestamp on the snowpack hero.
What's the elevation at Mammoth Mountain?
See the Resort Metrics panel above for base / summit / vertical drop. The summit elevation drives snowpack accumulation -- higher summits hold snow longer through spring.
How is "% of normal" calculated?
Today's snowpack is compared to the average snowpack on this calendar day across every recorded year at the nearest SNOTEL. 100% means right on average; 130% is a big year; 60% is thin.

See the Other Ski Areas pill grid at the bottom of the page for resorts within driving distance. The sister Other Ski Areas card in the Plan-a-longer-trip grid above shows the closest few.
Can I get alerts when fresh snow hits?
Yes -- snow alerts are managed in the Snoflo iOS app. Favorite this resort, set a snowfall threshold (e.g. "alert me when 6+ inches"), and you'll get a push the moment the SNOTEL crosses.
