Where this history comes from
Season totals are built from the Open-Meteo historical weather archive at Sundown Mountain's summit grid point (42.516, -90.819, ~1,059 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 Sundown Mountain snow report use observed station data where a SNOTEL or ACIS station is linked.
