Yukaghyr Upplands

The Moma Range rises east of the Indigirka and its tributary the Moma, among the rugged mountains of northeastern Siberia. Its long ridges overlook the Moma–Selennyakh depression to the west, while tributary valleys cut into the mountain country. The northern climate brings prolonged cold and snow to the heights, and the rivers descending from them feed the great waterways that eventually reach the Arctic seas.
