1957 Map of Clarksville

About this map

Columbia and its surrounding rural crossroads appear here during a transformative period in Howard County, as suburban expansion begins to meet established farming communities. This survey, based on 1943 and 1955 data with 1977 revisions, shows the early footprints of development near Simpsonville and the Hopkins Applied Physics Lab alongside longstanding local landmarks. Small rural centers like Highland and Dayton are anchored by family-named features and religious sites such as Linden Ch, St Louis Sch, and the Linthicum Cem. The landscape is defined by the winding course of the Middle Patuxent River and the Patuxent River, which feed into the Triadelphia Reservoir and the Rocky Gorge Reservoir. These water bodies and their surrounding drainages, including Hammond Branch, provide a clear view of the area's topography before the full intensity of modern residential growth.
