Forecast updated 26 Oct 2026, 12:08. Snowfall is modelled at each elevation, so summit totals are usually higher than the base.
We publish a piste map only once we have checked it against the lift company's own file, and we do not yet have a verified map for Mammoth Mountain. Most resorts release the new season's map between October and December, so this page will fill in as winter approaches. In the meantime, Mammoth Mountain has 150 pistes and 28 lifts, running from 2,423m to 3,369m.
