USGS Geoscience Data Catalog
Additional USGS Geoscience data can be found by geographic location or by publication series.
Boleneus, David E. , and Chase, Derrick W. , 1999, Digital analytical data from mineral resource assessments of National Forest lands in Washington: U.S. Geological Survey Open-File Report 99-344B, U.S. Geological Survey, Spokane WA.Online Links:
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.4.
The flattening of the ellipsoid used is 1/294.98.
Alan R. Grant (1982a,b) reported findings and conclusions of reconnaissance geology and probable future mineral activity target areas on the Colville and Okanogan national forests, Washington.
David Boleneus (USGS) and Derrick Chase (Eastern Washington University) compiled Grant's (1982a,b) data in a digital format using Microsoft's Excel97 spreadsheet program.

This dataset was developed to provide geochemical data for the Colville and Okanogan national forests, WA for use in future spatial analysis by a variety of users.
This database is not meant to be used or displayed at any scale larger than 1:63,360 (e.g., 1:62,500 or 1:24,000).
Grant, A.R., 1982, Summary report of findings and conclusions -- reconnaissance economic geology and probable future mineral activity target areas on the Colville National Forest, Washington: Colville National Forest, unpublished report, Okanogan, WA.
Grant, A.R., 1982, Summary of report of findings and conclusions -- reconnaissance economic geology on the Okanogan National Forest (excluding the Pasayten Wilderness Area), Washington: Okanogan National Forest, unpublished report, Okanogan, WA.
Johnson, B.R., 1987, GSMODS - A personal mineral occurrence database system reference manual, version 1.01: U.S. Geological Survey Open-File Report 87-636, U.S. Geological Survey.
Attribute accuracy was verified by manual comparison
of the source with hard copy printouts and plots.
Dave Boleneus estimated locations for eleven sample sites
based on descriptions provided in Grant (1982a,b).
The horizontal positional accuracy for the digital data
averages +/- 107 meters, but may be no better than
+/- 186 meters. It was tested by visual comparison of
the source with hard copy plots for 110 sites.
This digital dataset was produced from unpublished reports
(Grant, 1982a,b), and is considered to be a unique geochemical
dataset for the area.
Point data is given in latitude and longitude
(decimal degrees).
Are there legal restrictions on access or use of the data?
