Description :
The maximum extent zone of thhe Vistulian Glaciation in northeastern Poland is composed of a complex pattern with alternating dead and active ice features. The former include tripartite fabric of till in morainic plateaux as well as depressions of varying size, often with numerous secondary forms. Active ice zones represent probable ice streams within the ice sheet, reflected by outwash plains and previous subglacial channels. Different sediments in each zone suggest a coincidence of dead-ice features with cold ice whereas ice streams corresponded presumably with temperate ice that produced intensive meltwater outflow.
