Siberian Hills

The mountains between the Yana and Indigirka basins form part of the vast highland country of northeastern Siberia. Ridges and deep valleys divide rivers running toward the Arctic, including the Adycha and its tributaries. Forest occupies the lower slopes, while exposed high ground rises above it. Severe winter cold and a short summer shape a region far from either the Laptev Sea or the East Siberian Sea.
