West Siberian Glacial Lake
The West Siberian Glacial Lake, also known as West Siberian Lake (
Weichselian Glaciation, approximately 80,000 years ago. It was situated on the West Siberian Plain, and at its maximum extent the lake's surface area was more than 750,000 km2 which is more than twice that of the present-day Caspian Sea
.
It is theorized that although drainage to the Arctic Ocean basin (e.g. by the Ob and Yenisei Rivers) was prevented, the lake would eventually overflow to the
Selenga River and Lake Baikal draining over a course of some 9,700 kilometres (6,000 mi), considerably longer than any river's course today.[1]
