Yugoryonok (ru|Югорёнок) is an urban locality (an urban-type settlement) in Ust-Maysky District of the Sakha Republic, Russia, located 350km (220miles) from Ust-Maya, the administrative center of the district,[1] in a highly isolated region on the right bank of the Yudoma River. As of the 2010 Census, its population was 272.
It was founded in 1940 at a river port on the Yudoma, for use as a service base for the nearby goldfields. It was initially administered from Yur, located about 12km (07miles) away. With the cessation of gold mining in the 1970s, Yur was abandoned, and Yugoryonok was granted urban-type settlement status in 1978. With the cessation of mining activities in the 1990s, its population has decreased dramatically.
Within the framework of administrative divisions, the urban-type settlement of Yugoryonok[2] is incorporated within Ust-Maysky District as the Settlement of Yugoryonok. As a municipal division, the Settlement of Yugoryonok is incorporated within Ust-Maysky Municipal District as Yugoryonok Urban Settlement.[3]
Yugoryonok is located at the end of a 300km (200miles) road linking it with Eldikan on the Aldan River and the other gold-mining settlements in the area (now mostly abandoned). Yugoryonok was previously served by a small airport, which closed in the 1990s.
