FORT COLLINS, Colo. (AP) — A 29-year-old woman has died in an avalanche while skiing in northern Colorado, where communities along the Rocky Mountains have seen record or near-record snowfall since September.

The unidentified woman from Fort Collins was buried in the powerful slide Sunday, authorities said. Other members of her ski party dug her from the snow, but found that she wasn’t breathing, according to the Larimer County Sheriff’s Office.

The woman, whose name was not immediately released, was declared dead at the scene.

The avalanche happened at Diamond Peak just north of Rocky Mountain National Park. A 2- to 3-foot sheet of snow, ice and rock plummeted 500 vertical feet over a wide area, according to the Colorado Avalanche Information Center.

The center warned of considerable avalanche danger Monday for the Rocky Mountain Front Range, which includes the area where the skier died. The center urged people in the back country to use extreme caution after several rounds of early season snowfall.

Communities from Boulder north to Fort Collins broke or neared record snowfall levels for the three-month period between November and September, according to the National Weather Service.
