Loyalhanna Creek winds through this Westmoreland County landscape, anchoring a series of industrial and residential communities including Latrobe, Derry, and Bradenville. The geography is defined by the transition from the valley floor to the prominent ridge of Derry Ridge, where numerous hollows like Saint Clair Hollow and Rock Hollow carve into the terrain. This 2016 survey captures the modern footprint of settlements such as Peanut, Superior, and New Derry, while preserving the locations of legacy sites for genealogists, including Saint Josephs Cem, Rose Cem, and Saint James Cem.
