Chiginagak
About Chiginagak
The symmetrical, glaciated Chiginagak stratovolcano located on the Alaska Peninsula ~15 km NW of Chiginagak Bay contains a small summit crater, which is breached to the south, and one or more summit lava domes. Lava domes occur high on the NW and SE flanks of the calc-alkaline volcano. An unglaciated lava flow and an overlying pyroclastic-flow deposit extending E from the summit are the most recent eruption products, which most likely originated from a lava dome on the SE flank, 1 km from the summit. Brief ash eruptions were reported in July 1971 and August 1998. Fumarolic activity has been reported on the NE flank, and two areas of hot-spring travertine deposition are located at the NW base near Volcano Creek.
