Nittany Mountain and a series of parallel ridges define the landscape of this central Pennsylvania region during the late 1930s. The settlement pattern follows the narrow valleys, with Millheim and Aaronsburg serving as primary hubs along State Route No. 45. This era shows a transition in land use, as former industrial sites like the Sawmill near Ingleby give way to conservation and recreation efforts within the Bald Eagle State Forest.
