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.

The depth of the snow kept the heli-ski company from being able to recover the skiers Tuesday, an Alaska State Troopers spokesman said.

Efforts to recover the three men who died in an avalanche Tuesday while they were on a guided heli-ski trip in the Chugach Mountains near Girdwood were halted because of dangerous conditions and difficult terrain — and may not resume until conditions improve,

If the deaths are confirmed, it would be the deadliest U.S. avalanche since three climbers were killed in a slide in Washington's Cascade Range two years ago.

Minnesotans were in a group of skiers who are believed to be dead after an avalanche south of Anchorage this week, authorities have confirmed.

Radio Mankato identified one of the skiers caught in the backcountry avalanche as David Linder, who was part of a heli-skiing group.

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.

Alaska State Troopers said three skiers are likely dead after an avalanche buried them in the Chugach Mountains near Girdwood, Alaska, on Tuesday.

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.
