Sileenneex

The Selennyakh rises among the mountains of northeastern Siberia and flows through the Moma–Selennyakh depression to the Indigirka. The range bearing its name forms part of the Chersky mountain system, with rivers draining both eastward into the Indigirka and northward toward the Laptev Sea. Snow feeds the river, which freezes in autumn and opens again in late spring. Its long valley provides a contrast to the enclosing ridges.
