The AA. consider the possibility of the drainage of excess water from the Warsaw ice-dammed lake through the Warsaw-Berlin Pradolina. The lake was a result of a dam formed at the maximum of the Vistulian Glaciation. First, the question
of the relation between the Warsaw-Berlin Pradolina and the Warsaw ice-dammed lake is examined on the basis of various researchers' views on the origin and age of the levels and terraces, as well as the deposits of the Warsaw Basin.
instead of depositional or push end-moraines. The landscape development in relation to the melting of dead-ice is discussed as Laach tephra has been found in kettle holes and lake deposits undisturbed.
the following features of the marginal zone: ablation end moraines, marginal edges of outwash plains, ridges and depressions left by the melting of the cores of ice-cored moraines, collar ridges of melt-out lake basins, and marginal kames and kame-and-kettle
