Glacial Erosion/Sedimentation of the Baltic Region and the Effect on the Postglacial Uplift - The Baltic Sea Basin - page 62

of these early cycles. The surface is rough and sculpted, and significant material
has been completely removed from the Baltic-White Sea lowland area particularly.
Figure 3.4c shows the situation at the end of the interglacial period that followed
Fig. 3.4b . A layer of interglacial sediment has been laid over the rough lowland sur-
face, and as a result the surface is smoothed in numerous areas. Finally, Fig. 3.4d
shows the present situation that reflects intensive glacial erosion of mostly glacial
and interglacial sediments, with resulting cumulative effects of all the Quaternary
glacial cycles.
