1904 Map of Grantsville

About this map

Castleman River winds through the heart of the Maryland and Pennsylvania borderlands, a region defined by the prominent ridges of Negro Mountain and Savage Mountain. The landscape in the late 19th century was anchored by the National Road, which cuts westward through Grantsville, serving as a primary artery for trade and migration. To the south, the industrial character of the region emerges near the B and O R R corridor, where mining and milling activities supported communities like Moscow Mills, Barton, and Phoenix. The mapping shows a complex network of family-named landmarks and upland settlements such as Bittinger and Avilton, illustrating the dense agricultural and resource-based settlement patterns before modern forest conservation and highway developments altered the rural character of Garrett and Allegany counties.
