The Allegheny River and Kiskiminetas River converge at Freeport, forming a complex industrial and transport hub at the intersection of Armstrong, Butler, Allegheny, and Westmoreland counties. This late-twentieth-century landscape is defined by the legacy of heavy infrastructure, from the Conrail and Pennsylvania Railroad lines hugging the riverbanks to the extensive Water Treatment Plant and Filtration Plant facilities. The map captures a mix of dense valley settlements like Schenley and Garvers Ferry alongside upland residential growth in Natrona Heights.
