Indiantown Gap Military Reservation dominates the central landscape, showing the military infrastructure of the late 1960s with its airfields, ranges, and reservoirs like Marquette Lake and State Memorial Lake. The northern portion of the map is defined by the steep ridges of Blue Mountain, Second Mountain, and Sharp Mountain, where the Appalachian Trail follows the high ground. To the south, the terrain transitions into the agricultural valleys of East Hanover and North Annville. This map illustrates the remnants of 19th-century transport alongside modern interstate development, with the historic Union Canal and the Reading railroad corridor following the curves of Swatara Creek through Swatara Gap. Settlements such as Lickdale, Bordnersville, and Harper Tavern are visible, alongside local landmarks like Moonshine Ch and the Bashore Boy Scout Camp.
