Avalanches and avalanche paths share common elements: a start zone where the avalanche originates, a track along which the avalanche flows, and a runout zone where the avalanche comes to rest. The debris deposit is the accumulated mass of the avalanched snow once it has come to rest in the run-out zone.
A powder snow avalanche. An avalanche (also called a snowslide or snowslip) is a rapid flow of snow down a sloping surface. Avalanches are typically triggered in a starting zone from a mechanical failure in the snowpack (slab avalanche) when the forces on the snow exceed its strength but sometimes only with gradually widening (loose snow ...
The behavior of an avalanche depends on the structure of the snowpack, but that's only one ingredient. An avalanche requires all the wrong conditions at the wrong time. The angle of the mountain ...
Altogether, it constituted the greatest number of deaths caused by snow/ice debris from avalanches in history. When including all avalanche-related deaths (this includes mud and rock slides triggered subsequently by an avalanche), White Friday is the second-worst avalanche-related disaster recorded, after the 1970 Huascarán avalanche.

“This has been an avalanche.” Historian and American University professor Allan Lichtman answers questions during an interview with AFP in Bethesda, Md. on Sept. 7, 2024.
A tragedy occurred on Easter Sunday 1996 when an avalanche partially buried the Refuge and dozens of tourists. The glacier above the Refuge was probably weakened by an earthquake that had shaken the entire Province of Cotopaxi for several days prior to the avalanche. In the warm midday sun a huge portion of the ice wall broke loose.
As a massive winter storm dumped snow across much of the western U.S., winter sport enthusiasts headed to ski resorts and backcountry slopes ahead of the long Martin Luther King Jr. Day weekend.
Avalanche airbags work on the principle of inverse segregation (granular convection). [8] Avalanches, like mixed nuts and breakfast cereal are considered granular materials and behave fluid-like (but are not liquids) where smaller particles settle to the bottom of the flow and larger particles rise to the top.
