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 two geotiff files showing areas of
hydrothermally altered rock. These data were compiled for use
with an ongoing mineral resource assessment of theGrand 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 intrusion and areas of hydrothermal
alteration.
