Energy Resources Program
Compilation of existing geologic maps of the northern foothills of the Brooks Range, from the Chukchi Sea eastward to the Canadian border. This work is a collaboration between the USGS and the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys (DGGS) and the Division of Oil and Gas. It will result in a synthesis of geologic mapping that was conducted independently over several decades by the USGS and DGGS and will be produced at a fraction of the cost of new, field-based geologic mapping of the same area. A report of revised stratigraphic nomenclature for common use on all maps was completed in 2003.
The following maps are a product of the USGS Digital Geologic Maps of Northern Alaska project, which captures in digital format quadrangles across the entire width of northern Alaska. Sources include geologic maps previously published in hardcopy format and recent updates and revisions based on field mapping by the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys and Division of Oil and Gas, and the U.S. Geological Survey. Individual quadrangles are digitized at either 1:125,000 or 1:250,000 depending on the resolution of source maps. The project objective is to produce a set of digital geologic maps with uniform stratigraphic nomenclature and structural annotation, and publish those maps electronically. The paper version of this map is available for purchase from the USGS Store.
