Les causes [de déclenchement d’une avalanche] proviennent le plus souvent de conditions météorologiques datant de plusieurs jours, voire de plusieurs semaines, ces conditions ayant entraîné la formation de couches fragiles, responsables d’une mauvaise liaison entre les couches supérieures et le reste du manteau neigeux. [...] Conséquence de l'interaction de nombreux paramètres, dont certains sont difficilement quantifiables ou encore mal connus, le risque d’avalanche n’ est pas mesurable. Son estimation ne peut donc s’envisager que dans le cadre d’une expertise humaine. Une fois fixées les échelles de travail dans l'espace et dans le temps, le prévisionniste avalanche base son expertise sur un ensemble de mesures et d’observations effectuées sur et dans le manteau neigeux. 5, record 1, French, - pr%C3%A9visionniste%20avalanche

The shovel shear test provides information about the location where the snow could fail in shear. It is best applied for identification of buried weak layers and does not usually produce useful results in layers close to the snow surface.

Shovel Shear Test. This test can be done on a flat or on a slope. With good technique, the location of weak layers, even thin weak layers, can be found. First dig a hole or pit in the snow. The vertical wall of the pit should be straight up and down, and smooth. Make a mark on the uphill portion of one corner of your pit with your shovel blade. This will mark the boundaries of your column, which should be roughly 30 cm by 30 cm or 12 inches square. (A) Now, cut both sides using a snow saw or your ski, all the way to the floor of the pit making sure that the cuts are straight. (B) The back of the column should only be cut as deep as your shovel blade is long, so measure with your shovel blade (C) and then cut the back. (D) Next, insert your shovel, blade down, in the back cut of the column and pull gently and evenly forward being careful not to lever your shovel handle. (E) Examine the shear layer where the block failed. (F) The force applied to the shovel that causes a weak layer to shear from the layers surrounding it can be rated as follows: Very easy ...

Rounded Grains are those in which the original form is no longer discernible and the crystal takes on a generally rounded amorphous appearance. Rounded grains typically tend to be smaller grains and are usually significantly smaller than the original grain from which they formed. Typical grain size is often less than 1 mm. Commonly referred to as "rounds" these grains tend to be found in harder or stronger snowpack layers. Rounded grains typically form when there is a weak temperature gradient in the snowpack (<1 degree/10 cm). This weak temperature gradient occurs most often in areas where the snowpack is deep and temperatures are mild. 5, record 12, English, - rounded%20grain

Depth hoar [are] large coarse recrystallized grains of snow that are the end result of the faceting or squaring process within the snowpack, a process driven by temperature gradients. Such crystals are often weak and develop as a result of (locally) strong temperature gradients and resulting vapor pressure differences in the snowpack, especially in shallow snowpacks with cold air temperatures. These grains are formed through re-crystallization of existing snow grains as water vapor is transferred (sublimation and deposition) from warmer regions of higher vapor pressure (near the ground) to colder regions with lower vapor pressure (upper layers closer to the snow surface). 6, record 19, English, - depth%20hoar

The facetting process occurs within the snowpack and is driven by temperature patterns and vapour flow from ground to snow surface. Facets can form anywhere in the snowpack, but in certain climates basal facets are predominant. For example, in the Coast Range it is very rare to see basal facets but it is an annual occurrence in the Rocky Mountains.
