This is for the 1982 USGS Saturated Thickness of the High Plains Regional Aquifer in 1980, Northwest Oklahoma Open File Report 82-760. Map is great and the outside Folder shows crease and tears. Could be a crease in the map I did not see.
This is for the 2004 OGS Water Resources of Oklahoma City Quadrangle Central Oklahoma, Hydrologic Atlas 4, Map. This was originally published in 1975, but this is the fourth printing in 2004. There is a large colorful map that is in mint condition, along with the outside envelope.
