The relief created by the Poozerian glacier is complicated by numerous negative depressions formed as a result of exaration, evorsion, subglacial erosion, and glaciokarst processes.
Evorsion, along with active erosion by meltwaters and accumulation of glacigenic sediments, continued in the so-called Poznan Phase (about 17 000-18 000 BP).
