Set of processes, operating beneath or next to snow, believed to be responsible for the development of the hollows in which snow collects. It is also thought to play a role in the early formation of corries. The processes involved include freeze–thaw (weathering by the alternate freezing and melting of ice), mass movement (the downhill movemen......
