1952 Map of Duncannon

About this map

Duncannon sits at the vital confluence where the Juniata River meets the Susquehanna River, a landscape defined by industrial corridors and river navigation. In the early 1950s, the remnants of the Juniata River (Abandoned Canal) traced the water's edge alongside the active Pennsylvania Railroad, illustrating the shift from canal era transport to the rail and highway age. The topography is dominated by a series of parallel ridges, including Hickory Ridge and Mahanoy Ridge, which channeled development into the narrow valleys.
