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.
