The slide caught the heli-skiers late Tuesday afternoon in the Chugach Mountains near the skiing community of Girdwood, located about 40 miles (64 kilometers) south of Anchorage, said McDaniel. Heli-skiers use helicopters to reach mountains in remote backcountry areas where there are no ski lifts, and then they either ski or snowboard down.

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,

It appears to be the first fatal avalanche this winter in Alaska and the country's deadliest since an avalanche in Washington's Cascade Mountains killed three climbers in 2023.
