About this map

Portville stands at the confluence of the Oswayo River and the Allegheny River, serving as a central hub for the surrounding valley settlements in the early 1960s. The map illustrates a landscape defined by sharp elevation changes, where narrow hollows like Narvoo Hollow and Gleason Hollow lead away from the river plains into the high timber of Typnahda Mountain and the Ridge. Transportation is a key theme, with the Pennsylvania Railroad and the Pennsylvania Rd following the natural contours of the river valley.

Genealogists can identify localized communities such as Main Settlement, Obi, and Toll Gate Corner, along with the West Genesee Ch and Chestnut Hill Cem. The inclusion of several former transportation routes, including the Old RR Grade and the Carroll Grade, indicates an evolving infrastructure as older rail beds were repurposed for local transit or industry during this period of mid-century growth in Cattaraugus and Allegany Counties.
