The morphological development of alpine valley heads in the Antarctic Peninsula

Auteur :
HAYNES, V.M.

Description :
Glaciation has continued in Antarctica for longer than anywhere else on Earth, so the long-term development of glaciated landforms can be investigated. This study is based on a morphometric analysis of the plan form of 1680 alpine valley heads. Skewed distributions of dimensional properties (width, length and area) suggest that small corries are continually being added to the population, as older ones are enlarged and some eliminated by coalescence and ice sheet erosion. The attainement of an equilibrium planform shape is suggested by the persistence of an equidimensional form, and by the intercorrelation of morphometric properties.
