About this map

The Conowingo Dam and its massive Conowingo Reservoir dominate this landscape along the Maryland-Pennsylvania border. This survey, updated in the early 1950s, documents the industrial footprint of the Power Plant and Radio Towers alongside the historic Mason and Dixon Line. The map reveals a dense network of rural infrastructure, from the small hub at Darlington to the river-side facilities at Pilot Sta and Conowingo Sta.

Local genealogy and social history are well-represented by numerous country churches and burial grounds, such as Deer Creek Ch, Hosanna Ch, and St Patricks Cem. The transition from river-based transit to mid-century aviation is visible near Oakwood, where the Conowingo Airport sits just north of the reservoir. Communities like Rowlandsville and Peach Bottom are shown in relation to the winding Octoraro Creek and Conowingo Creek, providing a detailed look at the region's topography before later modern developments.
