Our mountaineering expert delves into the science behind avalanches to answer the question: why do avalanches happen?

Over the holiday weekend, a backcountry skier lost his skis but managed to escape without significant injuries after triggering a wet slab avalanche on Independence Pass near Aspen.

A 37-year-old man was killed after an avalanche "caught, carried and fully buried" him in the Utah backcountry while snowmobiling, officials said.

Nicholas Vizzini, 29, and his climbing partner triggered the avalanche as they were descending a slope, the National Park Service said.

Dry slab avalanches typically reach speeds up to 80 mph (129 kph) within seconds, according to the Sierra Avalanche Center. Wet avalanches usually travel around 20 mph (32 kph).

A missing skier who was found dead on Saturday was killed by an avalanche in Utah's Uinta mountain range, authorities said.

The death of an Olympic snowboarding athlete is a reminder that even the most skilled and experienced athletes are not immune to the threat of avalanches, and that knowledge is key to staying safe.

“This is the largest slab avalanche we’ve seen at Steamboat in almost two decades,” patroller Matt Hartsel said in the video.

Authorities are confirming the death of a skier who triggered an avalanche alongside his climbing partner, a snowboarder, while descending a slope in Denali National Park and Preserve in Alaska.

Each winter about 25 people on average die in avalanches in the U.S., with most occurring in the wilderness. Here’s a look at avalanches, how they occur and some tips on how to stay safe.
