Moraine - Types of Moraines

Types of Moraines

Moraines can be classified either by their origin, location with respect to a glacier or former glacier, or by their shape. The first approach is suitable for moraines associated to contemporary glaciers but more difficult to apply to old moraines whose glaciers have disappeared long ago. Moraines types like rogen and veiki moraines are defined by their particular morphology since their origin has been a matter of dispute. Some moraine types are only known from ancient glaciers, like the two former ones, while medial moraines of valley glaciers are poorly preserved and difficult to distinguish after the retreat or melting of the glacier.
