This digital geospatial data set consists of contours of lines of equal depth to the bottom of the Trinidad Sandstone, the contact between the Trinidad Sandstone and Pierre Shale, in Las Animas County, Colorado. The U.S. Geological Survey developed this data set as part of a cooperative project with the Colorado Water Conservation Board.

This data set consists of structure contours that show lines of equal altitude of the top of the Trinidad Sandstone, the contact between the Trinidad Sandstone and Vermejo Formation, in Las Animas County, Colorado. The U.S. Geological Survey developed this data set as part of a cooperative project with the Colorado Water Conservation Board.

This digital geospatial data set consists of potentiometric contours that show lines of equal altitude of the generalized, long-term, regional water table in the northern part of Las Animas County, Colorado. The U.S. Geological Survey developed this data set as part of a cooperative project with the Colorado Water Conservation Board.

For use as part of a regional petroleum assessment, the USGS in the early 1990’s developed a dataset reporting elevation on the surface of the Precambrian basement of the central and southern Colorado Plateau and vicinity (Butler, 1991). This dataset was released as paper report that included a table of basement elevations at more than 3,700 control points, including outcrop data of Precambrian rock on the plateau periphery, plus borehole data, seismic data, and depth estimated from a variety of published maps and stratigraphic sections. A contoured map of these data was released as a figure in an interpretive report (Blank and others, 1998). This digital dataset contains spatial datasets corresponding to the elevation of the Precambrian basement tabulated by Butler (1991) and the derived contour map (Blank and others, 1998). Basement elevation at control points is contained within a point feature class within the geodatabase. Points are attributed by type of data, method used to estimate top of Precambrian rocks from the data, and an estimation of the confidence in the reported elevation values. Contoured elevation data are contained in a line feature class within the geodatabase. Both types of data are also saved as individual shapefiles. Nonspatial tables define the data sources, terminology, and methods used.

This geospatial data includes oil and gas wells within the Colorado portion of the Raton Basin, as of January 2005. It includes a subset of over 60,000 existing and proposed oil and gas well locations within the State of Colorado. The well point data represent permitted locations, most of which have been drilled and completed, or drilled and abandoned. Some permitted locations were never drilled; these locations are also included in the shapefile. Selected well identification numbers and other header information are provided as attributes. The Colorado Oil and Gas Conservation Commission (COGCC) is the official repository for Colorado's oil and gas information. Links to the COGCC website and to the shapefile (WELL_SHP), which were used to develop this geospatial data, are provided in the Cross-Reference section in these metadata.
