1906 Map of Carnegie

About this map

Chartiers Creek and its many tributaries carve a dense network of valleys across this landscape southwest of the three rivers' confluence, where the industrial expansion of the early 20th century met rural hamlets and mining camps. The terrain is defined by the heavy presence of rail infrastructure, including the Pennsylvania RR and the Wabash Pittsburgh Terminal RR, which served the region's extraction economy at sites like Cliff Mine. Local life centers around a series of small settlements and post offices that have since shifted or consolidated, such as Gladden Gradatim PO, Treveskyn Cuddy PO, and Hills Lawrence PO. The northern edge captures the industrial riverfront near Neville Island, while to the south, the map documents the institutional presence of the County Home and the reform school at Morganza near the growing hub of Canonsburg.
