ICE-DAMMED LAKE IN THE SUKHONA RIVER VALLEY
Field studies were carried out in the Sukhona river basin, in the area of distribution of the Sukhonskoye proglacial lake. It is shown that the lake had a limited distribution along the Sukhona river valley from the border of the last glaciation in the area of Lake Kubenskoye to the mouth of the river Staraya Totma, and did not connect with the Vaga proglacial lake along the valley of the river Uftyuga. The reverse slope of the roof of the lacustrine sediments indicates the distortion of the valley of the modern Sukhona in its upper reaches in the postglacial time.
