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, and geologic hazards. A second geologic-hazards map shows non-derivative potential hazards compiled from published maps and reports, including faults, icings, avalanches, jokulhlaups, and permafrost.
