Greenwood Furnace and the industrial remnants of central Pennsylvania's iron history anchor this survey, where the ridges of Tussey Mountain and Broad Mountain dominate the terrain. The landscape is defined by its narrow valleys and water-powered history, visible in the cluster of small settlements like Ennisville, McAlevys Fort, and Saulsburg along Standing Stone Creek. The transition from early industry to mid-century conservation is evident at Whipple Dam and the Martin Gap CCC Camp, representing the work of the Civilian Conservation Corps in managing the region's timber and water resources.
