1957 Map of Millheim

About this map

Millheim and Aaronsburg serve as the primary hubs in this mid-century survey of the Pennsylvania Ridge-and-Valley province. The landscape is defined by the high, parallel ridges of Nittany Mountain and McCall Mtn, which isolate the agricultural settlements in narrow corridors like Sugar Valley and Brush Valley. This arrangement necessitated numerous named passages through the terrain, such as Gramley Gap, Smullton Gap, and Rockville Gap, which historically dictated the flow of travel and commerce between the valleys.
