North America's Snowiest Place

The greatest annual snowfall level in North America is at Mount Rainier, Washington, where an average of 692 inches (1,757.68 cm) accumulates every year. The single year record was set during 1971-1972 with 1,122 inches (2849.8 cm) of snow.

The highest mountain in Washington's Cascade Range, Rainier is also a dangerous stratovolcano that could erupt and set off massive mudflows fueled by the melting of the huge snowfields and glaciers that blanket its slopes.
