Kuolay

The Kuolay rises in the northeastern Verkhoyansk mountains and flows through mountain tundra before turning toward the Laptev Sea. Its lower course crosses a marshy plain dotted with lakes, and a broad estuary opens into Sytıgıy-Tala Bay on Buor-Khaya Gulf. Rapids and branching channels mark the river above the coast, while tides influence its lower reaches. The neighbouring Dyagaryn enters the gulf a short distance to the northeast.
