The Clarion River and Elk Creek define this industrial corridor of Pennsylvania's coal and timber country just before the mid-century. Centered on the borough of Ridgway and the city of St. Marys, the landscape is a dense network of extraction and transport. Multiple rail lines, including the Pennsylvania Railroad and the Pittsburg Shawmut and Northern, thread through the valleys to serve active operations like Dagus Mines, Kyler Mine, and Toby Mine.
