Where the Eastern Sierra desert collides with a dormant volcano, Mammoth rises in solitary splendour above the Long Valley Caldera. Five storeys of snow a year, runs that stay open through July, and a 3369 m summit that turns the Owens Valley into a sun-bleached map below.

Snow report FAQ

How fresh is the snow data?+

The current conditions and 7-day forecast are pulled from Open-Meteo (ECMWF, MeteoFrance, DWD and Met Norway models combined) and cached for 30 minutes. Numbers reflect conditions at the resort's latitude and longitude.

What does fresh snow mean?+

The amount of snow that has accumulated over the previous 24 hours, separate from the daily forecast for the next 7 days.

Why is current snow lower than the seasonal average?+

Snow depth varies day by day. Our seasonal average is an indicative monthly target based on altitude and historical reliability. The live number is what is actually on the slopes today.
