Port Allegany serves as the focal point of this McKean County landscape, where the Allegheny River meets Allegheny Portage Creek in a valley defined by deep hollows and narrow creek beds. The map reveals a high concentration of named topographical features that reflect local heritage, such as Ostrander Hollow, Sherwood Hollow, and Steel Hollow. These landforms, alongside water bodies like Lillibridge Cr and Combs Creek, dictate the winding paths of rural roads like Stagecoach Rd and Old Bush Mill Rd. For those researching local families, the inclusion of Fairview Cem, Saint Gabriels Cem, and Lewis Hill Cem provides specific points of interest. The northern portion of the map near Turtlepoint and the Simpson Cove wetlands illustrates the broader river system as it flows toward the community of Twomile, while the Johnson Airport stands as a more modern landmark on the outskirts of the primary settlement.
