2019 Map of Harlansburg

About this map

Slippery Rock Creek winds through the southern reaches of this landscape, anchoring a rural Pennsylvania region defined by small townships and traditional church-centered communities. In the village of Plain Grove, the Plain Grove United Presbyterian Church Cemetery stands as a significant genealogical marker for local families, while the settlement of Harlansburg serves as a crossroads near the Unity Cemetery. The map captures the meeting of three counties—Mercer, Lawrence, and Butler—highlighting how these political boundaries intersect with the natural flow of waterways like Taylor Run and Hottenbaugh Run. Researchers will find a preserved pattern of rural life, from the scattered homes at Brent and Rockville to the older industrial site of Elliotts Mills. This 2019 survey documents the enduring road networks and land divisions that have shaped the area for generations.
