The First Salpausselka at Lohja, southern Finland.

Abstract

Four morphogenic types of the First Salpausselka can be distinguished in the Lohja area: glaciofluvial marginal deltas, incompletely developed deltas, other ridges and hills, and formations with a rock core. The primary morphology has been considerably deformed by shore action during the stages of the Baltic Ice Lake, the Yoldia phase and the Ancylus Lake of the ancient Baltic.-from Author
