Hayes volcano, located in a remote and rugged part of the Alaska Range NW of Anchorage and north of Mount Gerdine, was not discovered until 1975. It was named after nearby Hayes Glacier and consists of scattered remnants of a largely snow-and-ice covered volcano that has been destroyed by catastrophic eruptions. The most widespread Holocene eruptions in the Cook Inlet area originated from Hayes volcano between about 3800 and 3400 years ago and produced six regional tephra layers with an average volume of 2.4 cu km. The latest known eruption took place about 1000 years ago.
