All of these Snowfall records occurred in the Western USA. We suspect there are some pretty big numbers coming out of Alaska, but there’s are no official records to go by.
Single Day Snowfall Record = 76″
From 2:30pm April 14, 1921 to 2:30pm April 15, 1921 Sliver Lake, Colorado received 76 inches (6+ feet) of snow. This storm didn’t stop after 24 hours, it raged for 32.5 hours straight and ultimately left 95 inches (8 feet) of snow, which is the record for one continuous snowfall. Silver Lake is at 10,220 feet and about 40 miles west of Denver.
Most Snow from a Single Storm = 189″
Mount Shasta Ski Bowl in northern California holds the record for the most snow ever received from a single storm system within the United States. A total of 15.75 feet (189 inches) of snow was measured from February 13-19 in 1959.
Most Snow To Fall In A Month = 390″
During the month of January 1911 Tamarack, California received 390″ of snow. That’s over a foot of new snow every day for a month. Tamarack’s location high in the Sierra Nevada Mountains near the border of California and Nevada make it an ideal location to intercept copious amounts of moisture provided by an active storm track off the Pacific Ocean.
Snow Depth Record = 451″
Tamarack, Calif. in the Sierra Nevada Mountains also holds the United States record for greatest snow depth ever measured. A maximum snow depth of 451 inches, or 37.5 feet, was recorded on March 11, 1911. Tamarack sits at 6,913 feet near Bear Valley ski resort.
12-Month Snowfall Record = 1,225″
The most snow to ever fall over a 12 month period was 1,225 inches (102 feet) at Paradise on Mount Rainer, WA from Feb. 19, 1971 – Feb. 18, 1972. The snow measurement was taken at an elevation of 5,400 feet.
