Conowingo Dam and its expansive Conowingo Reservoir dominate this 1953 landscape, marking a significant era of hydroelectric development on the border of Maryland and Pennsylvania. The map meticulously traces the historic Mason and Dixon Line, which divides the northern settlements of Pleasant Grove and Rock Springs from the Darlington and Berkley areas to the south. This survey captures the infrastructure of the mid-century river economy, featuring the Power Plant, the Pennsylvania Railroad corridor, and station stops like Conowingo Sta and Pilot Sta.
