(Redirected from Krummholz formation)A 'Krumholtz' or 'Krummholz formation' (from German: ''krumm'', "twisted"; and ''holz'', "wood") is a feature of
subarctic and
subalpine tree line landscapes, where continual exposure to fierce, freezing winds cause vegetation to become stunted and deformed. The wind kills branches on the
windward side, giving the tree a characteristic flag-like appearance. Where the lower portion of the tree is protected by snow cover, only the exposed upper portion have this appearance.
Common trees showing Krumholtz formation include
Subalpine Fir,
Subalpine Larch,
Engelmann Spruce,
Limber Pine, and
Lodgepole Pine.
