... recent cold temperatures combined with shallow snow is a dangerous mix, creating a weak snowpack that cannot hold much weight. [According to him] "slabby" snow is making the backcountry dangerous. Snow grains that have blown around and then stuck together are layered on top of a weaker layer of snow. This slabby layer, he said, gives a misleading feel that it is strong, but it can easily cave in on the weak layer beneath, causing an avalanche. 3, record 1, English, - slabby%20snow

Check out how well the new snow is sticking to the layer below and whether or not the new snow is cohesive and slab-like before riding a slope. Slabby snow on top of a weak layer is a recipe for large triggered avalanches. 1, record 1, English, - slabby%20snow
Record number: 1, Textual support number: 1 OBS
When used, "slabby snow" is always related to direct sensation of the snow by the observer whether by skiing or travelling through it, or by tests. This may be as a result of wind action on the snow, but could equally be due to the effects of sun or temperature on new snow layers. 2, record 1, English, - slabby%20snow

Record number: 1, Textual support number: 1 OBS
En France, seuls les adeptes de glisse, non pas les spécialistes en avalanches, utilisent le terme «neige plaquée». Ils en restreignent cependant le sens à la neige dure seulement. En effet, pour certains, une plaque est encore trop souvent de la neige dure. Ainsi, quand il y a de la poudreuse avec suffisamment de cohésion pour que la cassure linéaire dans la zone de départ se propage et donne une avalanche de plaque, ces adeptes ne disent rien, alors qu'ils disent «attention, la neige est plaquée» quand ils voient de la neige dure. 2, record 1, French, - neige%20avec%20une%20certaine%20coh%C3%A9sion

Lorsqu’elle s’arrête, l’avalanche à départ ponctuel laisse sur la pente une trace en forme de poire. Ces avalanches concernent surtout les pentes raides (plus de 35 degrés environ).

Glide is the process in which the snow cover on a slope slides downhill along the interface with the underlying ground ...

Full-depth avalanches often follow the formation of a glide crack ...
