The Rocky Mountain states have experienced avalanche activity in recent weeks that forecasters are calling ‘historic.’

Wyoming experienced some of its largest avalanches in decades. "These are thirty, fifty, maybe a hundred year events," says Bridger Teton Avalanche Center director Bob Comey.

The spate of slides culminated this weekend, with avalanches burying several roads and popular trails in the Jackson area.

Two dead in western Wyoming avalanches

Jan 28, 2013

Avalanches killed two skiers from Jackson in western Wyoming yesterday.  Elizabeth Gray Benson, 28, was west of Bondurant when an avalanche caught her and carried her into a tree. Nick Gillespie, 30, was in the north end of the Teton Range.

Bob Comey with the Bridger-Teton Avalanche Center says significant new snowfall on top of a slick, older base of snow means the risk for avalanches is considerable.

Parts of the Bridger-Teton National Forest got more than two feet of snow last week, which led to a considerable risk of avalanches.

The Bridger-Teton Avalanche Center has now reduced the risk to “moderate,” which means natural avalanches are unlikely but human-triggered avalanches are possible.

Lead forecaster Bob Comey says avalanches are often a result of people skiing, snowshoing or snowmobiling in the wrong place at the wrong time.
