Lower Gazimur
The lower Gazimur winds through the wooded hills of eastern Transbaikalia to join the Argun from the left. It is one of the principal tributaries of the Argun, whose waters unite with the Shilka to form the Amur. In the early 1720s Russian explorers investigated the Gazimur basin for silver deposits, part of a wider search for mineral wealth in the country between the Shilka and the Argun.
