Ukyulyaax
Lake Ukyulyakh lies in the Yana–Indigirka lowland between the Yana and Chondon rivers. Its freshwater basin occupies a thermokarst depression in the Arctic plain, a landscape marked by numerous lakes and marshes. The lowland stretches eastward from the Yana delta along the coast of the Laptev and East Siberian seas. Long winters freeze the waters, while the short summer reveals a country of shallow lakes and tundra.
