Snow devil
The snow devil is a rarely seen phenomenon. It occurs when surface wind shear acts to generate a localised vortex over snow cover that results in a whirling column of snow particles being raised from the ground.
The snow devil in this picture was observed from a location near the northern end of Abraham Lake in Alberta, Canada. This location is on the Kootenay Plains, immediately to the east of the Canadian Rocky Mountains.

A snow devil takes the form of a whirling column (a vortex) of snow particles that are raised from the ground and rotating about an approximately vertical axis. The phenomenon is also sometimes referred to as a snownado.
