It is known that during the period from 50 to 12 thousand years ago, the ice thickness of up to three kilometers covered northeastern North America until the middle of the Great Plains to the west and to the latitude of New York City in the south. In Northern Europe a solid ice cover reached the latitude of London and Berlin. At the same time the sea level was below the present more than 100 meters.
It is believed that such a distribution of ice masses was the result of a general cooling of the Earth. In geology, this period is called the Pleistocene. Then the whole territory of Siberia, down to the coast of the Arctic Ocean and Alaska, was free of ice, and it lived in a variety of different animals – mammoths, reindeer, woolly rhinos, cave bears and many others. So, the climate of Siberia was then quite soft.
