About this map

Duncannon sits at the confluence of the Susquehanna River and Sherman Creek, serving as a focal point for transportation and commerce in Perry County. The landscape is defined by the sweeping curves of the Juniata River as it passes landmarks like Trimmers Rock and The Narrows before merging with the Susquehanna. The presence of the Clarks Ferry Bridge and Juniata Bridge highlights the area's importance as a river crossing, connecting the town to Benvenue and the larger islands of Duncan Island and Haldeman Island.

Tracing the smaller waterways reveals a network of rural settlements and family-named infrastructure, such as Potters School and the Mosquito Creek Dam. Inland, the terrain rises toward Dicks Ridge and Half Falls Mountain, with narrow valleys holding communities like Montebello, Rose Glen, and Acker. The map documents a mature road network, including historic routes like Towpath Rd and River Rd, which follow the legacy of the river-based economy.
