Mount Iliamna is a glacier-carved volcanic peak located approximately 215 km (134 mi) southwest of Anchorage on the west side of lower Cook Inlet. Holocene eruptive activity from Iliamna is little known, but radiocarbon dating seems to indicate at least a few eruptions, all before the European settlement of Alaska. However, fumaroles located at about 2,740 m (8,990 ft) elevation on the eastern flank produce nearly constant plumes of condensate and minor amounts of sulfurous gases. These plumes are quite vigorous and have resulted in numerous pilot reports and early historical accounts of "eruptions" at Iliamna Volcano.
