      Process_Description:
        Dip approximated from North Dakota bedrock map on east-west cross sectional information spaced an 5000m used to construct digital surfaces in GoCAD software version 2.1.1pl - December 2004: Earth Decisions Sciences, for elevations of unit top. Surface combined with contoured pre-Creteacous bedrock surface for Minnesota. Surfaces converted to ZMAP grids, then to geotiff images to load into ArcGIS. Geotiff no data values set to ArcGIS nodata value
