About this map

Chartiers Creek winds through the heart of this industrial landscape west of Pittsburgh, serving as a primary corridor for a dense network of early 20th-century railroads. The concentration of transportation infrastructure, including the Pittsburgh and Charteirs RR and the Pennsylvania RR, highlights the era's reliance on rail to connect rural mining operations with urban centers. Settlements like Carnegie, Oakdale, and McDonald appear as established hubs, while smaller nodes such as Beechmont and Rennerdale cluster along the valley floors.

Local history and genealogy are supported by the inclusion of specific post offices and mines, such as Heidelberg Loupnex PO and the Cliff Mine. The transition from the Ohio River at Brunot Island to the interior townships of Collier and South Fayette reveals a landscape defined by the extraction economy and the logistical challenge of moving coal and goods through the rugged western Pennsylvania hills.
