1906 Map of Brownsville

Heavy extraction is evidenced by the Vesta Mine, while the navigational infrastructure of the river is marked by several installations such as Lock No 4 and Lock No 5. Beyond the industrial riverfront, the survey captures the inland transition to rural townships like Rostraver and Jefferson, where the historic National Pike cuts across the southern portion of the sheet near Krepp Knob. Genealogical researchers can locate numerous smaller communities such as Ginger Hill, Sunnyside, and Black Diamond.
