1977 Map of Confluence

About this map

The Confluence of several waterways dominates this 1977 orthophotograph, where the Youghiogheny River Lake meets the Casselman River and Laurel Run. The aerial perspective shows the distinct settlement patterns of the late 1970s, from the structured streets of Ursina to the smaller hamlets of Harnedsville and Dumas along the river valley. The landscape is defined by the sharp bends of the water and the elevation of Fort Hill, illustrating how the region's topography dictated the growth of these Pennsylvania communities.
