Minisink is a 1,320-acre archaeological landscape on the Pennsylvania–New Jersey border within the homeland of the Munsee-speaking Lenape, and for much of the 17th and 18th centuries it was their most important community. Human habitation here reaches back about 10,000 years, giving the area an exceptionally long archaeological record. Since study began in 1900, research has moved beyond artifact collecting to reconstruct Native cultures, daily life, and Lenape-European interaction in Munsee country. Discoveries have revealed a broader diet than once expected, and the site's scale, preservation, and continuity have made it one of the Northeast's most important archaeological locales, despite severe erosion from floods in 2004 and 2005.
