Snowiest Places in United States

Biggest Average Annual Snowfalls

Several spots scattered across the United States can count on plenty of snow each winter. By far the snowiest region in the country is the Cascade Mountains of western Washington state. Weather stations on both Mount Baker and Mount Rainier measure much deeper snows than anywhere else in the US. The Rainer Paradise Ranger Station located near alpine at 5427 feet (1654 m) on the south flank of Mount Rainier sets the national record for having the greatest annual average snowfall with its 676.2 inches (1717.5 cm).

Most Snow in One Day

The most snow to fall in any 24 hour period is 75.8 inches (193 cm), well over six feet, that landed at Silver Lake, Colorado. The mountain lake sits at 10,220 feet elevation about 40 miles northwest of Denver. Its record-setting snowstorm began at 2:30 pm on the afternoon of April 14, 1921.

Even after 24 hours, the snowflakes still kept coming and by 6 pm on April 15, 1921 a record 87 inches had landed. The blizzard continued non-stop for 32.5 hours, ultimately leaving 95 inches of fresh snow on the ground. This set yet another record for the deepest accumulation from one continuous snowfall.

The biggest snowfall for a single calendar day belongs to another Colorado location, Georgetown where 63 inches landed on December 4, 1913. This small town with plenty of history is nestled high in the mountains at 8,550 feet elevation. Another dozen states have also measured three or more feet of snow arriving in one day.
