Sosva

The Sosva rises in the northern Urals and flows eastward to join the Lozva, forming the Tavda in the Tobol basin. Its upper course is called the Bolshaya Sosva. Forests surround the river and its tributaries, among them the Turya. Copper mining began on the Turya in 1758, when the Verkhoturye merchant Maksim Pokhodyashin opened the first of several mines. Their products supplied the growing metalworks of the Ural foothills.
