Ridgway and St. Marys anchor this industrial corridor in Elk County, where the Clarion River and Elk Creek carve through the plateau. Surveyed just before the United States entered World War II, the landscape is defined by its extraction economy and a dense rail network. The Pennsylvania RR and Erie RR connect manufacturing hubs to remote extraction sites like Dagus Mines and Toby Mine.
