Photo Gallery

Hayes volcano, located in a remote and rugged part of the Alaska Range, is almost totally covered by glacial ice and was not discovered until 1975. The volcano, named for the Hayes glacier, consists of remnants of a largely snow-and-ice covered edifice that has been destroyed by catastrophic eruptions. The exposed rock in the foreground is South Dome. Hayes produced the most voluminous Holocene eruptions in the Cook Inlet area between about 3800 and 3400 years ago and was active as recently as about 1000 years ago.
