Arkhara
The Arkhara gathers the Gongor and Khara rivers on the slopes of the Lesser Khingan, then crosses a low country of forest and marsh toward the Amur. Its basin lies between the Bureya and the mountains farther east. Ancient rock drawings along the middle river testify to people who traveled and lived in this valley long before the modern settlement took its name. Tributary streams drain the wooded hills into the broad wetlands beside the great river.
