1958 Map of Keystone Dam

About this map

Keystone Lake dominates this landscape where the Arkansas River and Cimarron River converge, reflecting a period of significant hydrological and infrastructural change. Purple photorevisions from 1967 indicate the massive impact of the inundation, highlighting areas like the Cowskin Bay Recreation Area and Appalachia Bay Recreation Area that emerged as the shoreline shifted. The relocation of settlements is evidenced by New Mannford, situated near the St Louis - San Francisco railroad line. Local history is preserved in the locations of Dixie Cem, Sinnett Cem, and the Rigsby Sch, while the rural economy is marked by numerous Oil Wells scattered across the Cimarron and Hominy terrain. The map also identifies aviation history at the Keystone Landing Strip and recreational development within Keystone State Park.
