About this map

The Maryland and Pennsylvania Railroad anchors this mid-century survey, cutting diagonally across the landscape and connecting the sister towns of Delta and Cardiff. This corridor along the Pennsylvania-Maryland state line is defined by Slate Ridge, where numerous quarries signify the region's industrial heritage in slate production. Moving south into Harford County, the terrain softens into a network of small agricultural settlements like Whiteford, Pylesville, and Dublin.

Religious and community life is well-documented through scattered landmarks such as Slate Ridge Cemetery, Mt Vernon Ch, and the Slate Ridge School. To the east, the landscape transitions toward the Susquehanna River, featuring the Broad Creek Memorial Scout Camp near the winding waters of Broad Creek. The map meticulously records the intersection of industry and rural life, from the Fire Observation Station No 77 Whiteford to the numerous small mills along Deer Creek.
