The Chantalvergyrgyn, also called the Chantalveergyn, is a stream located in Chukotka Autonomous Okrug, Russian Far East. It is 222 km long, and has a drainage basin of 6620 km2. The name of the river in Chukot means “crossing the path to the Chaunts."

Geography

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. 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.

Fauna

Salmon, whitefish, vendace, grayling, rainbow herring, pike, burbot, bull trout, and loach are common in the Chantalvergyrgyn waters.
