An Anchorage man has died in an avalanche while backcountry snowboarding near Cooper Landing.

Jeffrey Cheng, a 33-year-old from Anchorage, was overtaken by an avalanche while snowboarding with two friends near the Crescent Lake Saddle Cabin on Saturday, according to a police dispatch.

Bryce Fischer and Cody Lourie, both of Anchorage, recovered Cheng from under 6 feet of snow and performed 30 minutes of CPR.

Fischer then left the scene to return to the trai head, where he had cell phone service and could call for help, according to the dispatch.

The U.S. Forest Service, Alaska State Troopers and Moose Pass Emergency Services responded with snowmachines, according to the dispatch. Cheng was located deceased at about 8 p.m. and transported to the Carter Lake trail head.

Next of kin has been notified.

As of Sunday morning, the avalanche danger remains high above the tree line and is considerable below tree line, according to the Church National Forest Avalanche Information Center.

After a day or two of intense snow, preceded by nearly two weeks of sunshine, the likelihood of triggering a large avalanche has increased dramatically.

“Human triggered large slab avalanches will be likely on steep windloaded slopes,” according to the report. “For anyone headed into the backcountry today, know that the likelihood of triggering a large and unsurviveable avalanche increases with elevation. Dialing back our terrain choices and sticking to slopes 30 degrees or less with nothing steeper above is wise, especially above the trees.”
