The ridge-and-valley landscape of Central Pennsylvania is defined by the parallel elevations of Tussey Mountain, Jacks Mountain, and Stone Mountain. In the mid-1930s, this area supported a network of valley settlements and rural industry, including the milling operations at Pine Grove Mills and Cornpropst Mill. The presence of Monroe Furnace and Greenwood Furnace points to the region's earlier industrial heritage, while the Mount Gap CCC Camp indicates New Deal era activity in the state's forests.
