Amgun

The Amgun is the largest tributary of the lower Amur. Formed by the Suluk and Ayakit among the Bureya mountains, it runs northeast through a broad valley of marshy taiga, dividing into numerous channels. Salmon and sturgeon inhabit its waters. In 1690, after the Treaty of Nerchinsk, Qing surveyors travelled through the Amgun basin to examine the frontier. Their journeys took them by the Nimelen towards the ranges between the river and the Sea of Okhotsk.
