    The Eruptions of Crater Peak Vent, Mount Spurr Volcano, Alaska: Chronology and Summary By John C. Eichelberger, Terry E.C. Keith, Thomas P. Miller, and Christopher J. Nye CONTENTS ABSTRACT. Where to stay near Spurr, Mount The timezone in Spurr, Mount is America/Dawson Morning Sunrise at and Evening Sunset at It's light Rough GPS position Latitude. °, Longitude. °, Elevation. m.

    Spurr is an active volcano that last erupted in and dominates this area in the Alaska Range. Flightseeing over this area you will get a great view of the way the volcano formed the area, and how the glacier is still forming it. The USGS (U.S. Geological Survey) publishes a set of topographic maps of the U.S. commonly known as US Topo Maps. These maps are seperated into rectangular quadrants that are intended to be printed at "x29" or Peak: mi.
