1970 Map of Poolesville

About this map

The Potomac River and the Monocacy River converge in this 1970s landscape, where the historic C & O Canal National Historic Park and its Towpath follow the river's bend. This survey documents a rural corridor of Montgomery County preserved through significant institutional and park land, including the Dickerson Regional Park and the sprawling National Institutes of Health Animal Farm near Elmer. Local infrastructure of the era is clearly visible, from the powerplant and its conveyor near the river to the Baltimore and Ohio Railroad connecting settlements like Dickerson, Barnesville, and Sellman. Small rural communities and historic crossroads are well-defined, featuring landmarks such as the Monocacy Aqueduct, Mt Zion Ch, and Elijah Ch. The map also captures several islands within the Potomac, including Mason Island and Cox Island, alongside the transition from agricultural fields to the burgeoning residential footprints in Poolesville.
