BackgroundKialagvik 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 volcano draws its name from the Eskimo word for Wide Bay, which lies beyond the mouth of Kialagvik Creek, NE of the volcano. 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 from Kialagvik.
