The Fisher Site in northwestern Greene County, Pennsylvania, preserves the remains of a Monongahela village in the Enlow Fork floodplain and is considered one of southwestern Pennsylvania’s most important prehistoric sites. Identified as the tenth known Drew Phase site, it stands out because this culture’s villages, including all previously known Drew sites, were typically built on hilltops, likely because of frequent warfare. Investigations beginning in 1962 and later excavations recovered nearly 1,100 artifacts, including animal bones, stone tools, and more than 500 potsherds, some with unique geometric designs. Its unusual intact floodplain setting, rare in a region where similar sites were often lost to development and mining, led to its National Register listing in 1982.
