ABSTRACT
During the last glaciation, the Laurentide Ice Sheet (LIS) created the spectacular glacial landscape of northern North America. This landscape preserves a detailed record of the former ice-sheet size, subglacial bed conditions and ice-sheet behaviour. This chapter discusses the distribution of glacial landsystems that were created along the southern margin of the LIS in the northern USA during the late Wisconsin Glaciation (Fig. 6.1). As we show, landforms and sediments along the southern margin of the LIS are not randomly distributed but are arranged in patterns, which suggest that climate, topography, bed conditions and the resulting ice-sheet dynamics combined to yield distinct landsystems.
