The Chantalvergyrgyn limits the western side of the Chantal Range of the Chukotka Mountains, just south of the Iskhodnaya. It passes through sparsely populated areas. Winters in its area are long and bitter, so that its surface remains frozen for over eight months every year. Salmon, whitefish, vendace, grayling, rainbow herring, pike, burbot, bull trout, and loach are common in its waters.
