Gamchen is a complex volcano composed of four stratovolcanoes, one of which is of Holocene age, atop a shield-like structure. Yuzhny Gamchen and Severny Gamchen are two steep-sided eroded stratovolcanoes of Pleistocene age. Edifice-collapse events at Gamchen during the early Holocene produced several large debris-avalanche deposits below the eastern flanks. Molodoi, a small stratovolcano with a well-preserved, shallow crater, is located on the east flank of Severvy Gamchen. Barany, a young stratovolcano with a youthful crater 500 m wide and 200 m deep, is located on the SE flank of Yuzhny Gamchen volcano. Barany (also spelled Baranii) has been the source of a young lava field that extends to the east and NE and was active between about 3600 and 3000 years ago. Lava domes are found on the flanks of the volcanoes; the youngest of these is Lukovitsa dome, which formed during the final stages of activity at Barany. No historical eruptions are known from the Gamchen complex.

The Komarov volcanic complex is seen in the foreground in this view from the north toward the southern part of the Gamchen volcanic range. The youngest cone of the Komarov complex, 2070-m-high Komarov, was built at the western end of a 2.5 x 4 km caldera. It is capped by two craters, one at the summit and the other on the upper east flank. The Gamchen massif beyond Komarov consists of three Late-Pleistocene and one Holocene cones. The perfect cone of Kronotsky volcano is seen on the far right horizon.

The Gamchen volcanic massif, consisting of one Holocene and three late-Pleistocene cones, is seen from the SE. The reddish Holocene cone in the foreground, capped by a 500-m-wide, 200-m-deep crater, is named Barany (or Baranii, meaning "Sheep's"). Stratigraphic evidence indicates that it grew in several spurts of activity 3600-3000 years ago. Yuzhny Gamchen (center) forms the high point of the Gamchen massif. Kizimen volcano is seen on the distant horizon left of Gamchen's summit.
