Kuban

Kuban, a river of southern Russia, rising on the W. slope of the Elbruz, in the Caucasus, at an altitude of 13,930 ft., races down the N. face of the Caucasus as a mountain-torrent, but upon getting down to the lower-lying steppe country S. of Stavropol it turns, at 1075 ft. altitude, towards the N.W., and eventually, assuming a westerly course, enters the Gulf of Kyzyl-tash, on the Black Sea, in the vicinity of the Straits of Kerch. Its lower course lies for some distance through marshes, where in times of overflow its breadth increases from the normal 700 ft. to over half a mile. Its total length is 500 m., the area of its basin 21,480 sq. m. It is navigable for steamers for 73 m., as far as the confluence of its tributary, the Laba (200 m. long). This, like its other affluents, the Byelaya (155 m.), Urup, and Great and Little Zelenchuk, joins it from the left. The Kuban is the ancient Hypanis and Vardanes and the Pshishche of the Circassians.
