Digital Representation of Isopach Maps for Selected Sequences of the Cretaceous Published by Reeside (1944) and Other Sources

Information of hydrogeologic and geologic importance from the U.S. Geological Survey Oil and Gas Investigations Map 10, "Maps showing thickness and general character of the Cretaceous deposits in the western interior of the United States" (Reeside, 1944) were digitized from scanned maps 1, 2, 9, and 10. Isopach contours were captured and, along with Geologic Map of North America (GMNA) units (Garrity and Soller, 2009) and High Plains aquifer bedrock formations (Torres and others, 1999), were used to interpolate thickness rasters for the Cretaceous period.
Data available in this data release are available in a single compressed (.zip) geodatabase (.gdb) of geologic period feature classes, including isopach contours, raster interpolation masks, control points, thickness rasters, and the georeferenced Reeside (1944) map images.
