About this map

Industrial expansion and rail networks define this Pittsburgh landscape during the early 1900s. The Allegheny River, Monongahela River, and Youghiogheny River serve as the primary corridors for development, with heavy rail infrastructure such as the Pennsylvania RR and the Baltimore and Ohio RR hugging the water's edge. This period shows a densely packed urban core transitioning into sprawling industrial towns like Wilmerding and Bessemer, while large greenspaces like Schenley Park and Highland Park are already established landmarks.

Local history and genealogy are anchored by massive burial grounds including Allegheny Cemetery, Homewood Cem, and Oakland Cem. Farther from the river forks, smaller settlements such as Unity Station, Sandy Creek, and White Ash illustrate the residential pockets forming between the many "runs" and creeks that carve through the terrain. The presence of Lock No 3 on the Monongahela indicates the importance of river navigation for the region's steel and coal economy.
