About this map

Brush Creek and Bushy Run carve through this Westmoreland County landscape, shaping a dense network of suburban and industrial settlements as they appeared in 2010. The main thoroughfares and the Norfolk Southern rail line anchor a cluster of communities including Irwin, North Irwin, and Manor. These towns are characterized by their proximity to historical infrastructure, such as the Coal Dam at Shafton and the Herminie Waterworks.

Genealogists and local historians will find significant detail in the placement of numerous burial grounds like Old Brush Creek Cemetery and Saint Michael Cemetery. Unique local landmarks such as the Sky Ranch Airport near Ardara and the American Legion Speedway in McCullough provide a record of regional recreation. The southern portion of the map transitions into the coal-influenced landscapes of Herminie and Edna Number One, where naming conventions reflect the industrial heritage of the Sewickley Creek watershed.
