Light, dry (low moisture content, typically 4–7% water content) powder snow is prized by skiers and snowboarders. [38] It is often found in the Rocky Mountains of North America and in most regions in Japan. [26] Spring conditions – A variety of melting snow surfaces, including mushy powder or granular snow, which refreeze at night.
Dust comes in a variety of types, each with different properties such as fire, ice, wind, gravity etc. There are four main kinds; these can be blended naturally or artificially to create new kinds. Crystalline Dust is stable enough to stay out in the open, but powdered Dust is highly volatile, and must be stored in special containers for safety.
Powdered sugar, also called confectioners' sugar and icing sugar is a finely ground sugar produced by milling granulated sugar into a powdered state. It usually contains between 2% and 5% of an anti-caking agent —such as corn starch , potato starch or tricalcium phosphate [ 1 ] [ 2 ] —to absorb moisture, prevent clumping, and improve flow.
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 snow does not melt slower gradually with distance from the trunk, but rather creates a wall surrounding snow-free ground around it. According to some of sources, North American spring ephermal plants like spring beauty ( Claytonia caroliniana ), trout lily ( Erythronium americanum ) and red trillium ( Trillium erectum L.) benefit from such ...
Snow Depth-This is a measurement from the snow surface to the ground in meters. It is commonly does over a large time span using immobile graduated stakes. Snow Water Equivalency- A measuring tool which represents the vertical depth of water that would accumulate in an area, if all the snow and ice were melted in that given area.

Snow sliders – The ability of a ski or other runner to slide over snow depends on both the properties of the snow and the ski to result in an optimum amount of lubrication from melting the snow by friction with the ski—too little and the ski interacts with solid snow crystals, too much and capillary attraction of meltwater retards the ski.
