Plateau icefield landsystem

Ice sheet imprints may be recorded as major landscape features such as overdeepened/widened and through-valleys transecting plateaux. If they exist, erosional forms on plateau tops will be aligned parallel/subparallel to main and through-valleys. Exotic erratics further demonstrate ice-sheet glaciation and ice-flow directions. Ice-sheet-produced land units and elements must be distinguished from the regional- to local-scale glaciation land units and elements, which comprise the plateau icefield landsystem shown in Fig. 20.1 (Rea & Evans, 2003) and discussed below.
