Most of the district outlines come from Streufert and Davis (1990) or Davis and Streufert (1990) and Plumlee and others (1995) and modified by Dana Bove (USGS, unpublished data). At best, the outlines are a guide to the districts and should in no way be construed to be the actual district boundaries. Purpose: To illustrate in a very broad sense, the location of mining districts in Colorado. Supplemental_Information: This dataset was extracted and reprojected from data assembled by Dana Bove (USGS, unpublished) for a report by Plumlee and others (1995).

This digital map is not to be construed as a legal representation of the mining districts. The data should not be used at scales larger than 1:500,000. Any hardcopies utilizing this data set shall clearly indicate this source. If the user has modified the data in any way, (s)he is obligated to describe the types of modifications performed on the hardcopy map. User specifically agrees not to misrepresent this dataset, nor imply that changes were approved by the USGS.

Dana Bove exported the data from an unknown format and imported them into an early version of MapInfo. Projection information of the early versions is unknown. Additional changes, and there are many, are undocumented. This data may be used as an illustration of general location of the mining districts. Completeness_Report: The data are considered complete for the purpose of displaying metallic mining districts in Colorado at 1:500,000 scale. Logical_Consistency_Report: The original data were provided by Dana Bove (USGS, unpublished data.)

The remaining fields (Code, P1, P2) are relicts of the original digitization in GSMAP (Selner and Taylor, 1993), an in-house USGS mapping software program.
