1945 Map of Sandy Spring

About this map

Olney and Brookeville serve as focal points for this mid-century Montgomery County landscape, which was undergoing significant residential expansion as documented by later purple revisions. The survey captures the suburbanizing countryside, where local landmarks like the Montgomery County General Hospital and Sherwood High Sch in Ashton define the community infrastructure. To the north, the Patuxent River and the large Triadelphia Reservoir dominate the terrain, bounded by the Patuxent River State Park. Smaller hamlets such as Unity and Sunshine remain relatively isolated amidst the network of waterways like the Hawlings River and Reddy Branch. This document provides a look at the area before the full density of modern development, preserving the locations of smaller rural institutions like Slade Sch and the original footprint of Sandy Spring.
