1945 Map of Sandy Spring

About this map

The Patuxent River and the newly formed Triadelphia Reservoir anchor this 1945 survey of eastern Montgomery County, which includes revisions through 1971. The map illustrates a transitional period for rural crossroads like Olney and Sandy Spring, where traditional agricultural patterns begin to meet late 20th-century residential growth. Significant institutional landmarks are visible, such as the Montgomery County General Hospital and Sherwood High Sch, alongside small rural schools like Slade Sch. The terrain is deeply carved by water, with the Hawlings River and Northwest Branch creating a network of ridges and valleys that historically dictated settlement locations. From the quiet hamlet of Brookeville to the recreational Golf Course and Camp Bennett, the map documents the community's evolution before extensive suburbanization fully transformed the landscape.
