Usa

The Usa is the largest tributary of the Pechora, joining it from the right after gathering waters from the northern Urals and tundra. Its name is of Finno-Ugric origin and has been interpreted as “tributary”; another explanation connects it with a Mansi word for the nelma fish. The Vorkuta is among its tributaries. Together these rivers drain a northern landscape of long winters, forest and open tundra toward the Pechora and the Arctic sea.
