The Chantalvergyrgyn (Russian: Чантальвэргыргын),[1] also called the Chantalveergyn, is a stream located in Chukotka Autonomous Okrug, Russian Far East. It is long, and has a drainage basin of .
The name of the river in Chukot means “crossing the path to the Chaunts."[2]
The Chantalvergyrgyn flows roughly northeastwards in its upper course, limiting the western side of the Chantal Range of the Chukotka Mountains, just south of the Iskhodnaya. Its source is very close to the Arctic Circle. Further down its course it bends and heads eastwards into the Ekityki from its left side.[3]
The river passes through sparsely populated areas. Winters in its area are long and bitter. The river surface remains frozen for over eight months. It usually freezes in Early October and stays under ice until June.
Salmon, whitefish, vendace, grayling, rainbow herring, pike, burbot, bull trout, and loach are common in the Chantalvergyrgyn waters.
