1969 Map of Portland Mills

About this map

Portland Mills serves as a focal point along the Clarion River in this detailed 1969 survey of Elk County. The landscape is defined by the intersection of industrial extraction and public lands, featuring the extensive Bear Creek Gas Field and the Allegheny National Forest. Transportation networks of the era are well-documented, showing the Penn Central and Baltimore and Ohio railroads following the river valley through State Game Lands No 44. Local landmarks such as Kings Airfield and the Ott Cem provide specific points of interest for genealogists and local historians. The presence of the Ridgway Reservoir on Big Mill Creek and various labeled runs like Italian Shanty Run and Bloody Run illustrate the complex drainage system of the Highland and Ridgway terrain.
