1952 Map of Seneca

About this map

The Potomac River corridor serves as the central artery for this mid-century landscape, where the Chesapeake and Ohio Canal parallels the river's Maryland shore near Seneca. The mapping reflects a transition between the established river-focused settlements of Montgomery County and the agricultural tracts of Loudoun and Fairfax Counties in Virginia. Notable landmarks like Blockhouse Point and a series of large river islands, including Watkins Island and Clagett Island, define the waterway's character before it reaches Great Falls. Inland, a network of historic roads such as River Road and the Leesburg Turnpike connect small communities and school sites like Forestville Sch. This survey, based on 1943 topography with 1952 cultural revisions, documents the region's rural structure before the rapid suburban expansion of the later 20th century, preserving the locations of numerous unnamed cemeteries and the early alignment of the Pipe Line.
