Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Chiginagak
Chiginagak is a glacier-covered edifice with hot springs near the base of the N flank. Recent eruption products include an unglaciated lava flow and an overlying block-and-ash-flow deposit on the east side. Photo by Alaska Volcano Observatory, U.S. Geological Survey

The symmetrical, calc-alkaline Chiginagak stratovolcano located about 15 km NW of Chiginagak Bay contains a small summit crater, which is breached to the south, and one or more summit lava domes. Satellitic lava domes occur high on the NW and SE flanks of the glacier-mantled volcano. An unglaciated lava flow and an overlying pyroclastic-flow deposit extending east from the summit are the most recent products of Chiginagak. They most likely originated from a lava dome at 1687 m on the SE flank, 1 km from the summit of the volcano, which has variably been estimated to be from 2075 to 2221 m high. Brief ash eruptions were reported in July 1971 and August 1998. Fumarolic activity occurs at 1600 m elevation on the NE flank of the volcano, and two areas of hot-spring travertine deposition are located at the NW base of the volcano near Volcano Creek.
