- Description:
-
- Abstract:
-
This personal GeoDatabase feature class represents a compilation of reconnaisance geologic mapping of the Lookout Ridge quadrangle, Alaska.
- Purpose:
-
This map is 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.

-
Line work and attributes are based from revisions by Mull, C.G., 2000-2001. Revisions are based on new field data, and also data from USGS professional paper--Brosge and Whiittington, 1966 professional paper on the Umiat-Maybe Creek area
- Process_Step:
-
- Process_Description:
-
The linework was captured by auto-vectorizing a 1:250,000 scale paper map. Feature classes were attributed based on the published thematic map.
