Mount Kukak

The almost completely ice-covered Kukak volcano lies west of Hallo Bay near the end of a glacier-covered range extending NE from Mount Katmai. A vigorous fumarole field at the southern base of the hydrothermally altered northern summit and is the only one of the Denison-Steller-Kukak chain of volcanoes to display geothermal activity. Two reports eruptions noted by Hantke (1959) appear to be erroneous. The report of a 1951 eruption is an apparent reference to a 22 July 1951 ashfall at Kukak Bay, which was attributed by Muller et al. (1954) to Martin volcano. A 1953 explosive "eruption" was single large puff of steam followed by steaming from caverns in Hook Glacier (Muller et al., 1954).
