Rivers and Lakes.
| Large
ice fields formed a natural dam and closed a drain of the rivers moving in the northern
seas. The modern Siberian rivers: the Ob, the Irtish, the Yenisei, the Lena, the Kolyma
and many others overflowed along glaciers, making large lakes, which were
united in a glacier system of thawn waters drain. The large part of this system was joined
by little rivers, and the waters followed from it to the southwest through the system of
the Novoevksinsky basin, which once was on a place of the Black sea. |

For evidence modern rivers and cities are
designated.

Further through Bosfor and Dardanelles the
water flew down to the Mediterranean sea. The whole square of that water-gathering basin
was about 22 million sq. km. It embraced the territory from Mongolia up to the
Mediterranean.
The such system of ice lakes was in the Northern America too. Along the
Lavrentiev shield the huge Agassis lake, the Mac-Conell lakes and the Algon lakes
stretched, which disappeared currently. By the way, the modern Great lakes of the Northern
America - Superior, Michigan, Huron, Erie and Ontario – are only a small rest of the
bygone lake system. |
