At least 14 people died in avalanches last week, the deadliest week of American avalanches on record

Jessen, Moughamian and Nyman are three of the 14 people who have been killed in avalanches since February 1. This is the highest number of avalanche deaths in a seven-day period since the US Forest Service’s National Avalanche Center began tracking deaths, according to Karl Birkeland, the center’s director.
Moughamian and three others were killed this weekend when an avalanche swept through a backcountry ski area near Salt Lake City on Saturday. Theirs are the most recent in a string of avalanche deaths in six states:
According to Avalanche.org, a site of the Colorado Avalanche Information Center, since the start of the season in December 2020, at least 21 people in the US have been killed in avalanches following nationwide avalanche accidents.
Avalanches also wreaked devastating damage around the world this week: a glacier eruption triggered an avalanche in India’s northern state of Uttarakhand on Sunday, killing at least 19 people

Why it’s been an active year for avalanches

There are two likely reasons why more avalanche deaths have occurred this year: more people are enjoying the outdoors in the wilder parts of the West and a “really dangerous snow pack,” said Nikki Champion, a forecaster at the Utah Avalanche Center.

This year’s avalanche season has likely been more active because of a “persistent weak layer” of snow, she said.

How to avoid avalanches and what to do if you get caught by them

Snowfall was relatively minor in November and December compared to years earlier, and because there were bouts of drought in early winter, those early snowfalls don’t clump together, she said. That weak layer of snow forms the basis of the snow pack in the west, including Utah, Colorado and Montana. All of the new snow is on top of that weak base, Champion said.

That layer has also been more persistent in recent years, she said. Utah and Colorado have less snow than normal, so that weak undercoat lingers for months.

The increase in the number of deaths can also be explained by the increase in the number of people visiting the hinterland of the West for skiing and hiking. With many ski resorts closed during the pandemic, “more people are choosing to enter the backcountry,” Champion said.

How to avoid getting caught in an avalanche

Champion recommends contacting local offices for the avalanche forecast. If you’re going to ski through the backcountry, bring the proper avalanche gear, she says, including a shovel, beacon and probe – and bring a partner.

However, the best advice is to avoid areas where an avalanche could occur, Champion said.

“This isn’t really a problem that you can outsmart,” she said.
