Meadowcroft Rock Shelter

Meadowcroft Rock Shelter is an archaeological site located near Avella in Washington County, in southwestern Pennsylvania in the United States. Artifacts found at the site are connected by some archaeologists with North America's Paleo-Indian culture of approximately 10,000 to 15,000 years ago.

The excavations there were begun in 1973 by local archaeologist James M. Adovasio . If the dating is correct, the site would be among the oldest known Native American cultural sites in the Eastern United States.

It was given the name Meadowcroft from the nearby Meadowcroft Village historical park.
