Geochemistry of some quaternary lavas from the Aleutian Arc and Mt. Wrangell

This publication contains previously unpublished geochemical analyses or re-analyses of lavas, magmatic inclusions, and a few gabbroic cumulate inclusions from Alaska volcanoes (Akutan, Augustine, Buzzard Creek, Dana, Douglas, Fourpeaked, Frosty, Great Sitkin, Iliamna, Kaguyak, Kiska, Okmok, Prindle Cone, Recheshnoi, Redoubt, Spurr, Ukinrek Maars, Vsevidof, Westdahl, Wrangell) collected by the authors and others over the past 35 years. It provides substantial data sets for three volcanoes (Vsevidof, Westdahl, and Douglas) for which little or no published data exist. All analyses were made by the GeoAnalytical laboratory at Washington State University in Pullman, WA. The ICP/MS data have been reduced using the 2006...

Geothermal Resources of Alaska

Between 1979 and 1982, the Alaska Division of Geological & Geophysical Surveys (DGGS) and the Geophysical Institute, University of Alaska Fairbanks, undertook an assessment of the states geothermal resources under a program jointly sponsored by the U.S. Department of Energy and the State of Alaska. During this period, reconnaissance investigations of more than 100 thermal spring sites and fumarole fields located in Alaska were conducted by DGGS.

Pyroclastic-flow deposits atop Drift glacier. Deposits from different eruptive episodes of the Redoubt Volcano, Alaska. December 14, 1989-August 31, 1990.

Caption: Pyroclastic-flow deposits atop Drift glacier. These two layers were deposited during different eruptive episodes when domes collapsed down the north flank of Redoubt as hot, fast-moving avalanches of rock debris or pyroclastic flows. Deposits in this view are about 2 m thick; other flow deposits were as much as 10 m thick. Photograph by Cynthia A. Gardner. May 24, 1990.

Album caption: Nighttime Advanced Very High Resolution Radiometer image from a National Oceanic and Atmospheric Administration (NOAA) satellite of Redoubt Volcano in eruption at 3:17 a.m. AST (Alaska standard time) on December 16, 1989. The tephra plume extends downwind from Redoubt across Cook Inlet and over the Kenai Peninsula. Compare to figure 2. Snow, clouds, and plume are white; land and water are shades of gray to black. The image was processed by the EROS Alaska Field Office (U.S. Geological Survey) in Anchorage, Redoubt Volcano, Alaska. 1989-1990.

Ash fall contour map of the 2009 eruption of Redoubt Volcano, Alaska: Digital shapefiles of contours and sample locations

The 2009 eruption of Redoubt Volcano included 19 major tephra-producing explosions. Mass per unit area (MPUA) ash fall sampling of the resulting deposits allowed us to create isomass contours of the ash fall. This dataset contains the vector digital shapefiles of the ash fall contours for the explosive events. In addition, a point digital shapefile is included that describes more than 400 ash fall samples that were collected. For a detailed account of the 2009 eruption of Redoubt Volcano, see Schaefer, J.R., ed., 2012, The 2009 eruption of Redoubt Volcano, Alaska, with contributions by Bull, Katharine, Cameron, Cheryl, Coombs, Michelle, Diefenbach, Angie, Lopez, Taryn, McNutt, Steve, Neal, Christina, Payne, Allison,...

Photograph illustrating the effects of an outburst flood due to volcanic activity: Redoubt Volcano, Chigmit Mountains. Spurr district, Cook Inlet region, Alaska. 1963.

Photograph illustrating the effects of an outburst flood due to volcanic activity: Redoubt Volcano, Chigmit Mountains. Photo shows conditions before eruptions began in January 1966. This large, unnamed glacier shown here descends from the summit crater. Although the glacier is littered by much debris on its lower reaches the spectacular ice cascades on the mountain slopes are almost debris free, indicating recent decades of little volcanic activity. Kenai quadrangle, Spurr district, Cook Inlet region, Alaska. August 1963. Published on sheet 3 in U. S. Geological Survey. Hydrological investigations. Atlas HA-455. 1971.
