Season-to-Date Snowfall
This Season-to-Date 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.

Season Snowpack Trend Depth of snow compared to the average, highest, and lowest in recorded history (usually 20-40 years).
Base Depth vs Average Depth of snow compared to the average snow depth for that day.
Base Depth Monthly Change Depth of snow by month. Positive indicates above-average snowfall.
Calculated from 4 SNOTEL sites within 49 miles of Mammoth Mountain at an average elevation of 8,772 ft (not from official resort measurements). We use weather stations because they update automatically and provide consistent measurements over many decades. This snowpack data is currently only available for resorts in the western U.S.
