Survey of geology, geologic materials, and geologic hazards in proposed access corridors in selected quadrangles, Alaska

As part of the Department of Natural Resources (DNR) effort to make final recommendations of federal land parcels to be considered for selection by the State of Alaska according to provisions of the Statehood Act, a decision was made to identify and evaluate potential access corridors. Corridor maps were compiled for a total of 78 quadrangles throughout Alaska. This map suite shows relevant geologic information at a scale of 1:250,000 for 10-mile-wide corridors straddling centerlines for proposed access routes throughout Alaska. The maps are based on geologic data compiled from existing, published mapping. Each compiled corridor geology map was used to derive maps of potential construction materials, data quality,...

Summit crater lake observations, and the location, chemistry, and pH of water samples near Mount Chiginagak volcano, Alaska: 2004-2011

Following the May 2005 acid crater lake flood at Chiginagak volcano, DGGS has been monitoring crater lake water that flows into Indecision Creek, Mother Goose Lake, and the King Salmon River.This data table provides information on water samples collected between 2005 and 2011 near Chiginagak volcano, including:sample ID, latitude, longitude, location description, pH, and cation and anion chemistry results.

Preliminary bathymetric map of Mother Goose Lake, Alaska Peninsula

In preparation for bottom sediment coring at Mother Goose Lake, bathymetric data was collected using a Lowrance Sonar "fishfinder" (model LcX-17M) in August 2006 and August 2007. A 5-meter bathymetric contour map of the lake bottom was constructed using the GPS-sonar data in conjunction with field observations. The contour data and GPS location and depth data are provided in ESRI shapefile format for use in Geographic Information System (GIS) software.

Preliminary database of Quaternary vents in Alaska

The Alaska Volcano Observatory (AVO) uses an informal set of names for about 140 'volcanoes.' Some names refer to large, complex volcanic centers, while others indicate only a specific cone. This publication expands the list of 140 named volcanoes to include all volcanic vents where magma has reached the surface over the past 2.6 million years. This database of all known (published, or unpublished with permission) Quaternary volcanic vents was developed to better describe the nature and character of Quaternary volcanism in Alaska and specifically to aid in the discussion of spatial and temporal patterns of Alaska volcanism. This list is a preliminary starting point, and we hope that it is updated and expanded by...

Geologic map of Mount Chiginagak volcano, Alaska

Mount Chiginagak is a hydrothermally active volcano on the Alaska Peninsula, approximately 170 km south-southwest of King Salmon, Alaska. This small stratovolcano, approximately 8 km in diameter, has erupted through Tertiary to Permian sedimentary and igneous rocks. The eruptive products of Chiginagak volcano record a history of chiefly andesite lava flows and associated block-and-ash flows. The oldest lavas exposed are Pleistocene in age and are found everywhere around the edifice except in the northeast sector, where Holocene lava flows dominate the landscape. Holocene activity has covered the northeast flank with rubbly-topped andesite lava flows that extend as far as 4.6 km from their source vent at the summit...
