    Description:
      Abstract:
        >This data set covering the western part of Colorado includes water quality data
        >from eight different sources (points), nine U.S. Geological Survey Digital Raster
        >Graph (DRG)files for topographic bases, a compilation of Tertiary age intrusions
        >(polygons and lines), and a raster layer showing areas of hydrothermally altered rock.
        >These data were compiled for use with an ongoing mineral resource assessment of the
        >Grand Mesa, Uncompahgre, and Gunnison National Forests (GMUG)and intervening Bureau
        >of Land Management(BLM)lands. This compilation was assembled to give federal land
        >managers a preliminary view of water within sub-basinal areas, and to show possible
        >relationships to Tertiary age intrusions and areas of hydrothermal alteration.
      Purpose:
        >These data were compiled for use with an ongoing mineral
        >resource assessment of the Grand Mesa, Uncompahgre, and Gunnison National
        >Forests (GMUG) and intervening Bureau of Land Management (BLM) lands.

           Analytical data was transferred from hard print copy to a digital spreadsheet format, which was subsequently 
           imported along with latitude and longitude data into Mapinfo GIS table format.  Latitude and longitude data
           for sample localities were obtained by visually tranferring original sample locations from 7.5 minute 
           USGS topographic maps onto digital DRG 7.5 minute maps, and automatically extracting coordinate data using 
           Mapinfo GIS software.  These initially unprojected point files were then reprojected to UTM NAD27 Zone 13 using Mapinfo
           GIS (to compatibly overlay upon UTM Zone 13 DRG data in ArcExplorer project views). Mapinfo format files were 
           exported to Arcview shape (*.shp) and ARC/INFO export format (*.e00) for this publication.

           Analytical data was transferred from hard print copy to a digital spreadsheet format, which was subsequently 
           imported along with latitude and longitude data into Mapinfo GIS table format. In addition, some specific notes
           regarding samples were extracted from sample location map sheets and inserted into specific attribute fields in 
           the Mapinfo database. Latitude and longitude data for sample localities were obtained by visually tranferring

          near Crested Butte, Colorado in 1997. Unpublished digital data by Wanty and others provided as Microsoft Excel
          tables.  Analytical data, location coordinates, and other pertinent data for springs and streams were extracted
          from this database and imported into Mapinfo GIS tables. Original coordinate data (in Excel files) were 
          calculated by military GPS. Minor errors in coordinate plotting (due to close proximity of some points) were corrected
          to hand plotted determination of locations on 7.5' USGS topographic base maps. Corrected point locations were
          plotted on 7.5' USGS DRG maps in Mapinfo GIS and coordinate data for these points were automatically extracted.
