Nearly two months after Jamie Pierreâs pre-season death in an avalanche at Snowbird, conditions havenât changed much around the West. Ski areas nationwide have scant, or at least below average, snowpacks. While reports from avalanche forecasters throughout the region have also been bleakâmost are noting the presence of extremely weak layersâskiers and snowboarders are still venturing into avalanche terrain.
Last week, two snowmobilers and one skier died in avalanches in Montana. On Dec. 29, veteran ski patroller Duncan MacKenzie died after being swept away near Pemberton, B.C. On New Yearâs Day, an avalanche on Berthoud Pass in Colorado took a skier for a 400-foot ride and buried him up to his neck, requiring a medical evacuation. Then, on Jan. 3, a snowboarder triggered a wall-to-wall slide on the Pucker Face of Cody Peak, outside the ropes at Jackson Hole, Wyo. (See video up top.)

On Dec. 31, an avalanche also claimed the life and partially buried two Canadian Mountain Holidays patrons near Revelstoke, B.C. It was the first heli or cat-skiing death since the 2009-2010 season, when two died. The avalanche ripped 75 meters wide on moderate terrain below treeline, even after another CMH group had skied the same area that day. A day earlier, skiers also triggered two slides near Golden, B.C., but none were harmed.
âThe preexisting snow is extremely weakâthe weakest, thickest layer of faceted snow I have ever seen in Utah in over a quarter century of avalanche forecasting,â wrote Bruce Tremper in his Utah Avalanche Center forecast on Dec. 30. Five days later he wrote, âYou may get lucky in this terrain, but I doubt it.â
The extremely weak layers throughout the West mean that even when the snow does come, risks will remain high.
âIt doesnât bode well for the future,â said Ethan Greene, the director of the Colorado Avalanche Information Center. âWe have mostly weak snow here in Colorado and where itâs not weak, we have strong snow sitting on top of weak snowâ¦ When we get snow on top, itâs going to set up for a very dangerous situation.â
Greene said that some layers are so weak they allow skiers to trigger avalanches from trails they wouldnât normally worry about. The skier that died in the avalanche in Montana was on low angle terrain, but the crack he triggered spread to a steeper slope above him.
âYou could be travelling in terrain that you donât consider avalanche terrain, thatâs low angle and safe,â said Greene. âIn this sort of scenario, the snow is so weak, cracks can shoot hundreds of feet and up into steep terrain that runs into low angle terrain.â
Skiers and snowboarders venturing into the backcountry should always check their local avalanche forecast so they are aware of which terrain poses risks. Find your local avalanche center hereâavalanche.org for the U.S., and avalanche.ca for Canada.
âThereâs always safe places you can go,â said Greene. âItâs just a matter of recognizing potential danger and using terrain to minimize your risk.â
