Alaska Wildlife Troopers said an avalanche buried three skiers under a blanket of snow between 40 and 100 feet deep in a small resort town.

Alaska State Troopers say three skiers who had flown by helicopter to a remote mountain range were swept away by an avalanche and likely killed under the weight of snow nearly as deep as a 10-story building.

A trio of skiers have been trapped by an avalanche in the Alaska backcountry, according to Alaska State Troopers. The slide happened late on Tuesday afternoon near the skiing community of Girdwood, located about 40 miles south of Anchorage, Austin McDaniel, a spokesperson for the troopers, told The Independent.
