Native Americans left the site during the American Revolutionary War. It was not re-discovered until many years later, when, in 1955, Albert Miller found the first artifacts in a groundhog burrow. The methods of excavation used at Meadowcroft are still seen as state-of-the-art. It is viewed as one of the most carefully excavated sites in North America.
The Meadowcroft Museum includes a recreation of an 1570s Monongahela Indian Village. It includes wigwams, recreated pre-historic artifacts and a 3 sisters garden. The guides present information about the people and how they lived.
