The Casselman River winds through the heart of Somerset County, where the industrial presence of the Baltimore and Ohio and Western Maryland railroads defines the corridor. Centered on the borough of Rockwood, the 1968 landscape is a mosaic of coal extraction and rural community life, marked by numerous strip mines that dot the hillsides of Milford and Black townships. This map captures the region’s evolution from timber and transit to a diversified economy, evidenced by the infrastructure at Rockwood Station and the developed recreation at Laurel Hill State Park.
