    • Raster Dataset Model of Nahcolite Resources in the Piceance Basin, Colorado

    Metadata Updated: October 8, 2025

    ESRI GRID raster datasets were created to display and quantify nahcolite resources for eight oil shale zones in the Piceance Basin, Colorado as part of a 2009 National Oil Shale and Nahcolite Assessment. The zones in descending order are: L-5, R-5, L-4, R-4, L-3, R-3, L-2, and R-2. Each raster cell represents a one-acre square of the land surface and contains values for nahcolite tonnage. The gridnames follow the naming convention _n, where "" can be replaced by the name of the oil shale zone.
