Geologic map of the Deer Island quadrangle, Columbia County, Oregon and Cowlitz County, Washington
Dataset Identification:
Resource Abstract:
This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents
the general distribution of bedrock and surficial deposits of the Deer Island 7.5-minute quadrangle. The database delineates
map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological
Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller.

purpose:
This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:24,000)
scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking,
landslide potential, mineral hazards, seismic velocity, and earthquake faults. In addition, the report contains new information
and interpretations about the regional geologic history and framework. However, the regional scale of this report does not
provide sufficient detail for site development purposes.
