Torom
The Torom rises on the eastern slopes of the Taykan Range and flows northeast between wooded ridges to an inlet of the Sea of Okhotsk. Larch forest covers the country near its lower course. After the Treaty of Nerchinsk, the boundary towards the sea remained disputed; peoples along the Tugur and Uda later identified the Torom, between those rivers, as a dividing line. Their understanding of the frontier survived in eighteenth-century accounts.
