Ol'de Trail

This passage crosses the high country east of the Yana, toward the mountains drained by the Selennyakh. Ridges and river valleys divide the inland watershed from the Arctic lowlands to the north. The Selennyakh system belongs to the Indigirka basin, while the Yana follows its own course to the Laptev Sea. Long winters and a short summer govern the conditions in which the valleys can be crossed.
