Dukin

Dukin lies in the valley of the Duki, a right-bank tributary of the Amgun. The river begins at the junction of the Left and Right Duki among the Badzhal and Duki ranges, and flows northeast to the larger river. In the 1680s Russian Cossacks built a winter post at the mouth of a river recorded as the Dukichan, collecting sable tribute before withdrawing from the Amgun country amid conflict with Qing forces.
