2016 Map of Portersville

About this map

Slippery Rock Creek Gorge dominates the western half of this quadrangle, where the steep, winding waterway is crossed by several notable spans including Kildoo Bridge, Eckert Bridge, and Harris Bridge. The landscape reflects a mix of early industrial heritage and modern recreational space, with historic sites like Kennedy Mill and McConnells Mill situated along the creeks that carved these deep valleys. To the east, the borough of Portersville sits near the western reaches of Lake Arthur, a major water feature that has reshaped the local topography. This 2016 survey captures the area’s complex road network, including the intersection of Old US Hwy 422 and modern routes, while also documenting smaller rural centers such as Rose Point, Pleasant Hill, and the grounds of Mount Hope Cem.
