Ust-Ynykchan
Ust-Ynykchan lies beside the Ynykchan stream near its meeting with the Semerka, in the forested highlands of eastern Yakutia. The Ynykchan is part of the Allakh-Yun drainage, whose waters ultimately reach the Aldan and the Lena. Mountain ridges and river valleys divide this inland country from the Sea of Okhotsk. Long winters bring ice and snow to the streams and surrounding forests.
