The three missing skiers who were reportedly buried under up to 100 feet of snow after an avalanche in the Alaska backcountry earlier this week have been identified, Alaska State Troopers said Thursday.

A trio of skiers is likely buried under an avalanche near Anchorage, Alaska, that occurred Tuesday afternoon, but dangerous backcountry conditions have so far stymied recovery operations, officials announced.

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.
