Overview
Kialagvik is a small, poorly known glacier-mantled stratovolcano NE of Chiginagak volcano with a Holocene central lava dome and associated pyroclastic-flow deposits (Riehle, in Wood and Kienle 1990). The central dome rises 350 m above an ice field that mantles the upper part of the volcano. Andesitic lava flows and overlying dacitic block-and-ash-flow deposits are exposed broadly on the SW flank and in a small area on the NE flank.
No historical activity is known.

About the Photo
The SE side of a Holocene dome at Kialagvik rises 350 m above a surrounding glacier. It lies at the NE end of a segment of the Alaska Peninsula that includes neighboring Chiginagak and Yantarni volcanoes. Lava flows and overlying block-and-ash-flow deposits are exposed on the SW flank and in a small area on the NE flank.
