avalanches

Avalanches can be dangerous and shut down highways on many of the roads going in and out of the Jackson area, especially on Highway 191 through Hoback Canyon. But in the last few years, the Wyoming Department of Transportation has been installing new technology there that’s helped control the problem.

Avalanche technician Jamie Yount said in 2013, they installed the first remotely controlled avalanche exploders in North America. He said the new equipment now allows WYDOT to trigger avalanches on their own schedule and on a closed highway.

The director of the Wyoming’s chapter of the Conservation Fund, Luke Lynch, was killed in an avalanche on Sunday. Lynch and three others had ascended Mount Moran in Grand Teton National Park when a wet slab swept them off the mountain. One other man was seriously injured but two others survived to make a rescue call.

Park spokeswoman Jackie Skaggs says it was the accumulation of fresh snow on top of winter snowpack that created the dangerous conditions.

A storm bringing more than 2 feet of snow to parts of Bridger-Teton National Forest last week is raising
alarms about the risk of avalanches just as skiers begin entering the backcountry.

Forecasters at Bridger-Teton National Forest Avalanche Center
elevated the slide danger to "considerable" at upper elevations.
Officials say that more than 16 inches fell at Grand Targhee Ski Resort Thursday, with
an additional 10 inches expected through the weekend.
