Snow drift at top of Mammoth Mountain

Snowfall History

At 11,053 feet, Mammoth Mountain boasts the highest summit of any California resort, making for deeper, better snow, and beautiful vistas. With 3,500 skiable acres, an average of 400 inches of snowfall, 300 days of sunshine per year, and a season that typically stretches Nov–June, Mammoth delivers big smiles on the slopes from first-timers to Olympians.

The 22/23 winter season is officially our snowiest season on record with over 700" at Main Lodge and close to 900" at the summit. Take a behind the scenes look at some of the depths we recorded across the mountain in this video taken on April 14, 2023.

Deep Snow Safety
Prioritizing snow immersion suffocation (SIS) safety is crucial for every winter enthusiast. SIS accidents occur when a skier or snowboarder falls into a tree well or deep, loose snow, leading to entrapment and suffocation. To enhance safety, always ski or ride with a partner and steer clear of the base of trees.

Additionally, waiting at the bottom of the lift won't help your partner if they find themselves stuck in a tree well. Your safety is a shared responsibility, so be mindful of each other's well-being on the slopes. Stick together, stay vigilant, and enjoy the mountain responsibly.
