[3] The Ukvushvuynen Range is the easternmost subrange of the Koryak Highlands, East Siberian Mountains.

To the northwest rises the Rarytkin Range and the Velikaya River flows into the Anadyr Lowlands.

The highest summit is 1,423 metres (4,669 ft) high Gora Krasnaya (гора красная), rising to the south of lake Yanragytgyn.

Vaamochka and Pekulney are coastal lagoons that lie on the southern side of the range.

[4] The Kakanaut River, a small river flowing southwards in the central part of the range into the NE bay of Lake Pekulney, gives its name to the Kakanaut Maastrichtian geological formation.
