Yrgiiçen

Yrgiiçen rises in the northern mountain ranges and flows southeast before turning east near Tumus-Khaya. It joins the Baky to form the Uyandina, a tributary of the Indigirka. The Kuranakh enters the Irgichen from the left, and deep pools below its mouth shelter grayling during winter. Long cold months bind the river with ice before spring releases the mountain waters again.
