Dead Sea Sea is an endorheic lake located in the Jordan Rift Valley, a geographic feature formed by the Dead Sea Transform (DST). This left lateral-moving transform fault lies along the tectonic plate boundary between the African Plate and the Arabian Plate. It runs between the East Anatolian Fault zone in Turkey and the northern end of the Red Sea Rift offshore of the southern tip of Sinai.

The Sukhona-Vychegda was an important east–west transportation route while the Northern Dvina-Yug was a north–south route. The upper Sukhona is now connected by the Northern Dvina Canal to the Volga–Baltic Waterway,
