1954 Map of Monongahela

About this map

The Monongahela River anchors this mid-century portrait of Pennsylvania industrial life, where coal extraction and river transit define the landscape. Extensive operations like the Mathies Mine and Bunola Mine are depicted alongside their associated mine dumps and infrastructure. The map reveals the high density of the river valley, from the established streets of Monongahela to the northern borough of North Charleroi. Settlement patterns follow the bends of the river and the tracks of the Pittsburgh and Lake Erie and Donora Southern railroads.
