Meadowcroft Rockshelter is an archaeological site located near Avella in Washington County, in southwestern Pennsylvania, United States. Meadowcroft Rockshelter, a rock shelter in a bluff overlooking Cross Creek (a tributary of the Ohio River), is located about 36 miles west-southwest of Downtown Pittsburgh and is part of the Pittsburgh Metro Area. It is operated by the Heinz History Center.
The site was excavated from 1973 until 1978 by a University of Pittsburgh team led by James M. Adovasio. Radiocarbon dates from the site indicated occupancy as early as 16,000 years ago and possibly as long as 19,000 years ago. The dates are still controversial, although some archaeologists familiar with evidence from the site agree that Meadowcroft was used by Native Americans in the pre-Clovis era, and as such, provides evidence for very early human habitation of the Americas. In fact, if the 19,000 years ago dating is correct, Meadowcroft Rockshelter is the oldest known Native American cultural site.
Meadowcroft Rockshelter has yielded Woodland, Archaic and Paleoindian remains, indicating evidence of the processing of animals, such as deer, elk, bird eggs, and mussels; as well as plants such as corn, squash, fruits, nuts and seeds. The site also has yielded many tools, including ceramics, bifaces, bifacial fragments, lamellar blades, a lanceolate projectile point and chipping debris. At least one basin-shaped hearth was reused over time.
It was given the name Meadowcroft from the nearby Meadowcroft Village historical park. Although sometimes referred to as "Meadowcroft Rock Shelter", the more accepted and popular term is "Meadowcroft Rockshelter".
Following construction of a new observation deck and enclosure, The Rockshelter had a reopening on May 10, 2008.
