Kheium

Kheium lies in the upper Uyandina basin near the Oymyakon, the first major tributary of that northern river. Lenok ascend the Oymyakon, and grayling and other fish inhabit the waters around its confluence. The Uyandina begins where the Baky and Irgichen meet, then crosses the northern country toward the Indigirka. Its valleys descend from rugged uplands into a landscape of lakes and long winter ice.
