1954 Map of Pine Grove

Evidence of rural community life is scattered throughout the hollows, including the Oak Grove Union Sch and Outwood Sch, alongside the Joliett Ch in the northern heights. A notable recreational and conservation corridor is visible as the Appalachian Trail traverses the crest of Blue Mountain at the southern boundary. Later revisions highlight the emergence of modern infrastructure, such as the Pine Grove Airport and a series of highway interchanges including Interchange 31.
