Landsystems of Glacial Deposition

Proximal Distal Lateral Moraine Slope

While clean and debris-covered glaciers show many similar features within their landsystems, they differ in the dominant processes operating at the ice margin and in the relative development of landforms (Figs 15.4 and 15.5). Figure. 15.4 A landsystem model for valley glaciers with relatively low supraglacial debris inputs.
