1935 Map of Donegal

The industrial character of the era is evident in the rail spurs serving coal patches such as Mammoth and Calumet at the western edge of the sheet. Further east, the terrain becomes more pronounced toward Painter Rock Hill, where early named crossroads like Stahlstown and Kregar serve as local hubs. The map also preserves the locations of early postal outposts, including the Mansville Post Office and Buchanan White Post Office, providing a valuable record of early 20th-century mail routes through these Westmoreland County hills.
