Potomac River crossings and the vital Chesapeake & Ohio Canal corridor define the southwestern edge of this late 19th-century landscape. This survey represents the interconnected rural economies of Frederick, Carroll, Howard, and Montgomery counties, where transportation networks like the Baltimore & Ohio R. R. and Penna R. R. began to reshape the older agricultural order. The topography is dominated by the prominent rise of Sugar Loaf Mtn., a landmark standing in contrast to the numerous creek valleys that supported early industry.
