About this map

The ridge-and-valley landscape of Central Pennsylvania is dominated by the massive parallel formations of Bald Eagle Mountain, Tussey Mountain, and Brush Mountain in this 1984 topographical survey. The city of Altoona and the borough of Tyrone anchor the region's urban centers, which are connected by a heavy industrial corridor featuring the Conrail rail line and major routes like US Highway 220. This era captures the transition between traditional mountain industry and modern conservation, as evidenced by the vast stretches of Moshannon State Forest and recreational developments at Prince Gallitzin State Park surrounding Glendale Lake.

Hydrography defines the western plateau, where the West Branch Susquehanna River and Clearfield Creek wind through deeply incised valleys. Smaller settlements like Coalport, Houtzdale, and Carrolltown are interspersed with numerous state game lands, including State Game Lands No 108. The map also details unique topographical features such as Sinking Valley and the expansive wooded area known as The Barrens near the Centre County line.
