1994 Map of Seneca

About this map

The Potomac River serves as the dominant spine of this 1994 landscape, where the historical border between Maryland and Virginia is defined by a complex network of islands and navigation structures. Significant local heritage is preserved along the northern bank within the Chesapeake and Ohio Canal National Historical Park, where several numbered locks like Lock 24 and Lock 23 remain as evidence of early transit. Settlements such as Darnestown, Seneca, and Rushville anchor the Maryland side, while Lowes Island and Dranesville define the Virginia interior. The transition from established community to protected conservation land is clear, with large tracts dedicated to Seneca Creek State Park and Blockhouse Point Park. Genealogists and local historians can find specific family-history markers such as Leighs Cem and the Dranesville Tavern Park near the crossroads of the southern landscape.
