Razvika
Razvilka lies in the mountain country west of Kyubeme, near the Khandyga River. The Khandyga drains the western side of the Verkhoyansk mountains toward the Aldan, while rivers east of the watershed belong to the Indigirka system. Forested slopes and narrow valleys divide these great drainage basins. Deep winter cold and a brief summer shape the passage through this rugged interior of northeastern Siberia.
