"An avalanche down a steep couloir or rocky ravine running over a cliff, in the Himalaya, as seen in the upper reaches of Himachal Pradesh, India.
According to Wikipedia:
""An avalanche is a sudden, drastic flow of snow down a slope, occurring when either natural triggers, such as loading from new snow or rain, or artifical triggers, such as snowmobilers, explosives or backcountry skiers, overload the snowpack. The influence of gravity on the accumulated weight of newly fallen uncompacted snow or on thawing older snow leads to avalanches which may be triggered by earthquakes, gunshots and the movements of animals. Avalanches are most common during winter or spring but glacier movements may cause ice avalanches during summer. Avalanches cause loss of life and can destroy settlements, roads, railways and forests. From a geophysical perspective, avalanches are an example of a non-critical, punctuated equilibrium system. Typically occurring in mountainous terrain, an avalanche can mix air and water with the descending snow. Powerful avalanches have the capability to entrain ice, rocks, trees, and other material on the slope. Avalanches are primarily composed of flowing snow, and are distinct from mudslides, rock slides, and serac collapses on an icefall. In contrast to other natural events which can cause disasters, avalanches are not rare or random events and are endemic to any mountain range that accumulates a standing snowpack. In mountainous terrain avalanches are among the most serious objective hazards to life and property, with their destructive capability resulting from their potential to carry an enormous mass of snow rapidly over large distances.
Avalanches are classified by their morphological characteristics and are rated by either their destructive potential, or the mass of the downward flowing snow. Some of the morphological characteristics used to classify avalanches include the type of snow involved, the nature of the failure, the sliding surface, the propagation mechanism of the failure, the trigger of the avalanche, the slope angle, slope aspect, and elevation. The size of an avalanche, its mass and its destructive potential are rated on a logarithmic scale, typically of 5 categories, with the precise definition of the categories depending on the observation system or geographic region in which the avalanche occurs.""
I wonder if a Snow Leopard has ever been trapped in an avalanche?
