The Sobolokh-Mayan (Russian: Соболоох-Майан; Yakut: Соболоох Майаан, Soboloox Mayaan) is a river in Sakha Republic (Yakutia), Russia. It is the 20th longest tributary of the Lena, with a length of 411km (255miles) and a drainage basin area of 13300km2.
Lenok, taimen and whitefish are found in the waters of the Sobolokh-Mayan. There are no settlements by the river.[1]
The Sobolokh-Mayan is a right tributary of the Lena. Its source is located in the northern sector of the Verkhoyansk Range, at an altitude of roughly 1500m (4,900feet) on the western slope of the Orulgan Range, with its valley flanking the northern side of the Byrandia Range in its upper course.[2] In its first section the Sobolokh-Mayan flows across mountainous terrain. After leaving the mountains it flows into the Central Yakutian Lowland, forming meanders in the flat permafrost floodplain, until it joins the right bank of the Lena 700km (400miles) from its mouth, near the mouth of the Khoruongka in the opposite bank.[1]
Its longest tributary is the 254km (158miles) long Nyimingde.
