Avalanche danger remains high in Colorado, thanks to several rounds of heavy snow that moved through the area in February. Three snowmobilers were partially buried by debris when they were caught in an avalanche north of Granby on Saturday.

The slide happened on Gravel Mountain near Grand Lake just before 2:30 p.m. The Colorado Avalanche Information Center said that three or four people were caught in the avalanche, but were able to get out on their own or with the help of bystanders. It is believed to have been triggered by a snowmobile.

Sarah Steinwand, 41, of Crested Butte, Colorado, was caught in the debris of the avalanche in the backcountry near Silverton, but a man who was skiing with the snowboarder escaped

A snowboarder in Colorado's backcountry was killed in an avalanche west of Silverton on Thursday.

As one man became buried, the other tried to locate him by using his avalanche rescue transceiver, officials with the Colorado Avalanche Information Center (CAIC) said.

A snowmobiler was rescued after being buried in an avalanche, Colorado officials said. On Monday the snowmobiler was caught in an avalanche on Shrine Mountain in Vail Pass, according to an accident report by the Colorado Avalanche Information Center.

In a separate incident, four people caught in another avalanche escaped serious injury, Colorado officials say.
