The Catoctin Mountain range dominates the western portion of this 1943 survey, creating a physical barrier between the Frederick Valley and the higher elevations of the Blue Ridge. Along this ridge line, the border between Maryland and Pennsylvania is clearly marked, separating communities like Blue Ridge Summit and Monterey from the lowlands. The central and eastern landscape is defined by the winding Monocacy River and its many tributaries, including Toms Creek and Owens Creek, which powered early industry at sites like Hoovers Mill and Eicholtz Mill.
