[2] The name of the river in Chukot means “crossing the path to the Chaunts.

"[3] 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.

Further down its course it bends and heads eastwards into the Ekityki from its left side.

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.
