Periglacial

Periglacial is an adjective originally referring to places in the edges of glacial areas, but it has later been widely used in geomorphology to describe any place where geomorphic processes related to freezing of water occur. In the original meaning of periglacial area, areas described by the term were not buried by glacial ice, but were subject to intense freezing cycles and exhibit permafrost weathering and erosion characteristics.
