Where this history comes from
Season totals are built from the Open-Meteo historical weather archive at Big Sky's summit grid point (45.262, -111.401, ~11,166 ft), summed October 1 to September 30. They are modeled, not resort-reported, so they are consistent across resorts but can differ from a resort's own stake readings. Current-season numbers on the Big Sky snow report use observed station data where a SNOTEL or ACIS station is linked.
