Artifacts recovered from Shippingport were similar to those from other Ohio Valley Mississippian period sites. Chipped stone tools included triangular arrowheads, drills, scrapers, and knives. Among the groundstone artifacts were discoidals, pipes, and celts.
Ceramic vessels were mainly plain, fabric-impressed, and negative-painted jars, bowls, plats, bottles and pans - typical of Mississippian ceramics from sites throughout the lower Ohio River Valley. Unlike earlier Mississippian sites in the Falls Region, however, investigators recovered a substantial amount of Fort Ancient ceramics at Shippingport. These vessels were cordmarked jars with plain necks, many of which were decorated with rectilinear and curvilinear designs.
Investigators documented both wall-trench and single-set post houses at the site. House size ranged from 13 by 13 feet to 16 by 16 feet. These structures tended to be oriented northwest/southeast. Most had a prepared central hearth, and evidence for hearth cleaning and reuse at the site was common. Small interior storage pits, benches, and racks were associated with several structures. All had been repaired repeatedly, and most had been burned when they were abandoned.
