About this map

The Conowingo Dam and its massive Power Plant dominate the river landscape of this 1940s survey, marking a period of significant hydroelectric development on the lower Susquehanna River. The map captures the complex geography where the river meets the Chesapeake Bay, featuring the prominent industrial and transport hub of Havre de Grace and the neighboring Veterans Hospital at Perry Point. To the north, the historic Mason and Dixon Line serves as the political boundary between Maryland and Pennsylvania, cutting through rural communities like Rock Springs and Sylmar.

Tracing the rail networks reveals the importance of the Pennsylvania Railroad and the Baltimore and Ohio Railroad in connecting coastal towns. Local life is documented through numerous country landmarks, including Lees Mill, the Brookview Cem near Rising Sun, and several small schools like Locust Grove Sch. This survey provides a look at the region's transition from a mill-and-farm economy toward modern infrastructure.
