USGS Geoscience Data Catalog
Jack E. Harrison, Earle R. Cressman, James W. Whipple compiled the geology and published the original geologic paper map.
EROS Data Center staff scanned/digitized geologic map and prepared the original ArcInfo data prior to 1994.
Montana Bureau Mines and Geology acquired the original data and, in 1999, provided it to the USGS in Spokane, WA.
R.J. Miller (USGS) converted the original data to a single topologically correct ArcInfo coverage.
Helen Z. Kayser (contractor) attached and attributed an interim geologic map data model.
Thomas P. Frost (USGS), Pamela D. Derkey (USGS), and William N. Kelley (contractor) visually compared the hard copy plots with the source documents;
This dataset was developed to provide geologic map GIS of the Kalispell 1:250,000 quadrangle for use in the future spatial analysis by a variety of users.
This database is not meant to be used or displayed at any scale larger than 1:250,000 (e.g., 1:100,000 or 1:24,000).
Are there legal restrictions on access or use of the data?
