| Some
scientists consider that one of the largest ice lake in Eurasia was the Mansiyskoe lake,
or, as it is still named, the West Siberian lake. It took practically the whole territory
of the west Siberian flatnland up to foothills of the Kuznetsk Alatau and Altai. Those
places, the largest Siberian cities Tyumen, Tomsk and Novosibirsk are located where
in the last Glacial Epoch were covered with water. When the glacier became to thaw -
16-14 thousand years ago - waters of the Manseyskoe lake started gradually to
flow down to the Northern Ice Ocean, and on the place of this lake the modern river
systems of the Ob-Irtish basin were formed, and in a low part of the Taiga-Ob area the
largest in Eurasia system of Vasuganskie swamps formed. |
