Gases rise from a sulfur-encrusted, ~2 m high fumarolic vent on Mutnovsky. Widespread fumarolic activity occurs in several craters. The Verkhneye fumarole field covers a 3,200 m² area of the NW part of the active crater. The Donnoye fumarole field on northern Mutnovsky occupies a former crater lake.
