The Pennsylvania Maryland Boundary Line bisects this landscape, showing a region where commerce and geology ignored state borders at the turn of the century. The Maryland and Pennsylvania RR winds through the hills, connecting northern Harford County settlements like Pylesville and Whiteford to the twin border towns of Cardiff and Delta. This rail corridor was essential for the local extractive economy, evidenced by the Mc Intyre Minefield and industrial nodes like Furnace.
