Russian Land Between Seas49.1N 44.9E
The Russian land north of the Caucasus Mountains and the border with Georgian stretches between the Ukraine (left) and Kazakhstan (right).
The Volga River and Volgograd Reservoir form a right angle at the center, from the Volga carries on to its delta in the Caspian Sea (lower right). East of that right angle are a series of salt lakes, most of which lie in Kazakhstan.
Also near the center are the Don River and Tsimlyansk Reservoir, from which the Don continues until it reaches the Sea of Azov (lower left). The Sea of Azov then connects to the Black Sea via the Kerch Strait.
Sediments are present along the shores of all three seas, though they are particularly intense at the mouths of the Don and the Volga Rivers.
