Deep within the Allegheny National Forest, the Clarion River carves a winding path through the high plateaus of Elk and Jefferson Counties. This 1940 survey reveals an industrial landscape transitioning toward conservation, where the Baltimore and Ohio railroad line hugs the riverbank to reach timber and coal outposts like Portland Mills and Arroyo. The presence of the Empire Tunnel and a CCC Camp near Croyland highlights the era’s intersection of resource extraction and New Deal-era infrastructure.
