About this map

First Fork Sinnemahoning Creek carves a deep path through the Cameron and Potter County highlands, serving as the central artery for this remote Pennsylvania landscape. The valley floor is home to small pockets of activity near First Fork and Lushbaugh, where early industry and utility are evidenced by a Gaging Sta and a long-reaching Pipeline. Steep ridges like Grove Ridge and M Ridge are defined by an intricate network of tributary runs, including Rattlesnake Run and Lick Island Run, which underscore the rugged topography that historically limited large-scale settlement.

Local history is anchored by the presence of Gilmore Cem and Smith Cem, positioned on the narrow benches of the creek valley. These burial sites, alongside features like Berne Run and Mill Run, provide vital markers for genealogists tracing families in Grove and Gibson townships. The map reflects a mid-century moment when the natural environment remained the dominant force, with infrastructure like the Pipeline Road representing the few modern incursions into the high plateau country.
