Statement of Significance (as of designation - April 19, 1993):
Minisink was the most important Munsee Indian community for much of the 17th and 18th centuries. Archeological resources located here have yielded information on historic contact between Indian and European people in Munsee Country, a region stretching from southern New York across northern New Jersey to northeastern Pennsylvania. Today, Minisink remains one of the most extensive, best preserved, and most intensively studied archeological locales in the Northeast.

Two 100-year floods, T.S. Ivan in September 2004 and the Spring flood in April 2005, caused severe erosion to one of the contributing archeological sites, 36Pi04 (Manna Site) located at the confluence of the Raymondskill Creek and Delaware River. The park, with the assistance of the Department of Anthropology, Temple University, began site data recovery investigations in 2002 in preparation for bank stabilization of the Raymond Creek. About 20% of the site has been compromised.

Recommendation/Change since last report:
After the flood events, bank stabilization including grading of bank.
