5. Alta, Utah
Utah's tiny town of Alta may have a mere 383 residents, but it tips the scales with its massive 516-inch average annual snowfall. The excellent snowy conditions have made the town a popular ski destination, luring a half million visitors to its fabled powder each season.
Alta Ski Resort gained notoriety among snow sports enthusiasts for its ban on snowboarding; the move may seem exclusionary, but it has been a major selling point for ski purists visiting the mountain.
