Season Snowfall
This Season Snowfall number should not be quoted by resorts or the media or used for official climate statistics. This number is calculated from resort reported snowfall (where available) and OpenSnow estimated snowfall, and may be adjusted to match official data. While we believe that this number reasonably approximates the seasonal snowfall, in most cases OpenSnow does not verify this data.

Calculated from 4 SNOTEL sites within 49 miles of Mammoth Mountain at an average elevation of 8,772 ft (not from official resort measurements).
