DESCRIPTION
From Wood and Kienle (1990) [1]: "Pogromni volcano is a steep-sided stratovolcano on the southwest end of Unimak Island. All of the lavas analyzed from Pogromni are tholeiitic basalt. A single glacier is found on Pogromni. Outcrops in the glacially scoured walls of Pogromni suggest a caldera collapse was followed by building of the present cone. Another peak (Pogromni's Sister, 1,230 m) may be a remnant of this older vent.

"Five cinder cones are aligned with Pogromni volcano along a northwest-southeast trend. The monogenetic cones are 50-100 m high and are strongly oxidized on the surface.

"Pogromni volcano is little know. Reconnaissance petrologic studies report a few analyses from the satellitic cinder cones."
