New snow – Snow that has fallen since the previous day's report. Packed powder – Powder snow that has been compressed by grooming or by ski traffic. Powder – Freshly fallen, uncompacted snow. The density and moisture content of powder snow can vary widely; snowfall in coastal regions and areas with higher humidity is usually heavier than ...
The pack is designed to inflating if a victim becomes caught in an avalanche. The device helps the victim stay close to the surface if they are being carried in the snow, and the inflation of the device helps create a barrier between the victim and the snow to help prevent them from being suffocated by the snow.

Snowpack is an accumulation of snow that compresses with time and melts seasonally, often at high elevation or high latitude. [1] [2] Snowpacks are an important water resource that feed streams and rivers as they melt, sometimes leading to flooding. Snowpacks provide water to down-slope communities for drinking and agriculture. [3]

Snow grooming is the process of manipulating snow for recreational uses with a tractor, snowmobile, piste caterpillar, truck or snowcat towing specialized equipment. The process is used to maintain ski hills, cross-country ski trails and snowmobile trails by grooming (moving, flattening, rototilling , or compacting) the snow on them. [ 1 ]
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 ...
What to Look for in a Gas Snowblower. Gas snowblowers are designed to move lots of snow. They’re effective against snowbanks piled up to 2 feet high, and can clear out larger zones, including ...
Large, angular snow crystals are indicators of weak snow, because such crystals have fewer bonds per unit volume than small, rounded crystals that pack tightly together. Consolidated snow is less likely to slough than loose powdery layers or wet isothermal snow; however, consolidated snow is a necessary condition for the occurrence of slab ...
