The famed Horseshoe Curve of the Pennsylvania R. R. serves as a dominant landmark on this map of central Pennsylvania, illustrating the early 20th-century engineering required to traverse the Alleghenies. The landscape is defined by the sharp ridges of Loop Mountain, Dunning Mountain, and Tussey Mountain, which channel settlement and industry into the narrow valleys. The Frankstown Branch Juniata River provides the primary drainage for the region, where numerous communities such as Hollidaysburg, Duncansville, and Roaring Spring developed around rail junctions and natural springs.
