Photo Gallery


Late Pleistocene-Holocene cinder cones in the foreground dot the southern part of Tolmachev Dol (Tolmachev Plateau) with conical Opala stratovolcano in the background. Tolmachev Dol is a large volcanic highland NE of Opala volcano that is blanketed with numerous postglacial cinder cones. The cones and associated lava fields cover a broad area around scenic Lake Tolmachev halfway beween Opala and Gorely volcanoes.

Chasha ("Chalice") crater filled with a lake is in the middle of the photo. It formed about 4600 years ago and produced about 1 km3 of rhyolitic tephra (marker ash layer OPtr). Chasha crater is located in the northern part of the Tolmachev Dol (Plateau) and surrounded by Holocene basaltic cinder cones. The next lake at the left was dammed by the Chasha eruption products. The most distant water at the left is Tolmacheva Lake; Tolmacheva river valley is between Chasha lake and distant cones at the right.
