1947 Map of McHenry

About this map

Deep Creek Lake dominates the central landscape of this western Maryland survey, winding through the valleys between Negro Mountain and Marsh Hill. The 1940s shoreline reflects a maturing recreational and water-resource landscape, with early developments like McComas Beach and the Thayerville settlement taking shape. Significant public lands, including the Thayer State Game Refuge and the Savage River State Forest, define the eastern and northern reaches, preserving the high ridges of the Alleghenies. In the rural uplands, evidence of established community life appears in the form of local institutions like Beachy Sch and Casselman Sch, alongside Glendale Ch and Glade Ch. The map records the early road network that connected these remote points, including the Deep Creek Bridge and Glendale Bridge, as well as the prominence of the Thayerville Lookout Tower on Meadow Mountain.
