The boundary between Armstrong Co and Indiana Co runs through this section of Western Pennsylvania, where the landscape is defined by the winding course of Crooked Creek and its many tributaries. The 1960s economy is clearly visible through numerous Gas Wells and a prominent Conveyor system near Idaho, reflecting the region's industrial ties to energy production. Local life centers on established boroughs and settlements like Elderton, Shelocta, and Atwood, each connected by a network of rural roads and the Baltimore and Ohio railroad line in the southern valley.
