Hayes Volcano

Hayes Volcano is a stratovolcano in southwestern Matanuska-Susitna Borough, Alaska, 135 km northwest of Anchorage, that was not discovered until 1975. It is responsible for a series of six major tephra layers in the Cook Inlet region of Alaska. Hayes was mostly destroyed by at least six catastrophic eruptions between 3,400 and 3,800 years ago, and the average volume of these eruptions was 2.4 cubic km. In comparison, the volume of the May 18, 1980 eruption of Mount St. Helens was about 1 cubic km. The eruptions of Hayes Volcano during that time were the most voluminous Holocene eruptions to have occurred in the Cook Inlet region. There is currently no fumarolic activity present. The last eruption of Hayes Volcano occurred roughly 1,200 years ago. It is named after the adjacent Hayes Glacier.

Famous quotes containing the words hayes and/or volcano:

    I marched in with the men afoot; a gallant show they made as they marched up High Street to the depot. Lucy and Mother Webb remained several hours until we left. I saw them watching me as I stood on the platform at the rear of the last car as long as they could see me. Their eyes swam. I kept my emotion under control enough not to melt into tears.
    —Rutherford Birchard Hayes (1822–1893)

    We are like travellers using the cinders of a volcano to roast their eggs. Whilst we see that it always stands ready to clothe what we would say, we cannot avoid the question whether the characters are not significant of themselves.
    Ralph Waldo Emerson (1803–1882)
