Los Angeles : An avalanche swept up and killed three snowmobilers in Alaska on Friday, authorities said.
The three were snowmobiling near Turnagain Pass, about 70 miles(112 kilometers) south of Anchorage, when the avalanche occurred, Alaska State Troopers said.
The snowmobilers were burried in the snow for nearly an hour before they died, Troopers spokeswoman Beth Ipsen said.
Attempts to resuscitate the three were unsuccessful, she said.
The avalanche occurred after 11 inches of snow fell in the area in the past two days.
A warning has been issued against high danger this weekend in south-central Alaska, including natural avalanches and huge snow slides.
The victims were not immediately identified.
