About this map

The Susquehanna River Conowingo Reservoir dominates this landscape, its waters held by the massive Conowingo Dam and its adjacent Power Plant. This 1990s record of the borderlands between Maryland and Pennsylvania shows the river's transformation from a natural waterway into a managed energy source, punctuated by islands like Rowland Island and Sterret Island. Along the northern edge, the historical Mason and Dixon Line divides the map, separating Harford and Cecil Counties from Lancaster, York, and Chester Counties.

Settlement patterns reveal a mix of small hamlets and agricultural history, with Darlington and Conowingo Village serving as local hubs. Religious and educational centers, such as St Patricks Ch and Rock Springs Sch, are scattered across the terrain, indicating the community's long-standing roots. Industrial and logistical features like the Quarry and Conowingo Airport contrast with the natural preservation of Susquehanna State Park, while the remnants of rail infrastructure at Conowingo Sta and Pilot Sta speak to the area's former transportation network.
