2023 Map of Harlansburg

About this map

Slippery Rock Creek winds through this rural landscape of northwestern Pennsylvania, where the borders of Mercer, Lawrence, and Butler counties converge. This 2023 survey illustrates the enduring settlement patterns of small communities like Harlansburg and Plain Grove, which remain anchored by historic institutions. Genealogical interest is particularly high here, as the map documents several burial grounds including South Plain Grove Cem and Stevenson Cem. The topography is defined by several waterways, notably Jamison Run and Taylor Run, which feed into the primary creek valley. Local transportation is centered on arterial routes such as Harlansburg Rd and New Castle Rd, connecting older hamlets like Elliotts Mills and Rockville to the surrounding agricultural and wooded countryside.
