Sankina
The Sankina is a left-bank tributary of the Tura in the forested country east of the Urals. The Tura flows onward to the Tobol and the Irtysh, linking this river network with western Siberia. On the Tura, the Russian stockade of Turinsk was founded in 1600 to guard the route between Verkhoturye and Tyumen. Farther into the forests, the Sankina and its smaller tributaries drain the country north of that route.
