It is also known as Sükebayatur and Sükhbaatar in Mongolian, Stanovoy Mountains, or Outer Khingan Range.

The range runs south-west to north-east for almost 800 km, from the Olyokma River in the west, to the Uchur River in the east. almost to the Sea of Okhotsk. It separates the watershed of the Arctic Ocean (via the Lena) from that of the Pacific Ocean (via the Amur). For this reason, it was the border between Russia and China from 1689 (Treaty of Nerchinsk) to 1858 (Treaty of Aigun). The Aldan Highlands are located to the north of the range and the Yankan – Tukuringra – Soktakhan – Dzhagdy group of mountain ranges to the south.
The Yablonovy Range may be considered a southwestern extension of the Stavonoy. Before the 20th century, Stanavoy could also refer to a somewhat mythical range along the west coast of the Sea of Okhotsk.
