1968 geological map of West Virginia. Also includes separate fold and fault coverages from the same map. In 1968 the West Virginia Geological and Economic Survey (WVGES) published a State Geologic Map. The topographic base was compiled from Army Map Service 1:250,000 scale map sheets. In 1998 the WV Division of Environmental Protection (WVDEP) scanned the hardcopy geologic maps at 300 dpi, 8-bit color, and then georeferenced them. Rock unit boundaries were digitized off the images and attributed by WVDEP. The USGS-Water Resources Division later revised the attributes of large water bodies and referenced the datum to NAD83.TEST
