Yenisei is a Turkic language (Turqi a son of Togarmah and great grandson of Japheth) spoken in the region of the Yenisei River which flows north from Mongolia through Russia into the Arctic Ocean, and the Na-Dene languages of North America (Athabascan, Cree, Navajo, and Apache) are related to the Yenisei language because those tribes are descended from the Yenisei (meaning mother river) having crossed the Bering Land Bridge during the Ice Age when sea level was a few hundred feet lower.
