Foundation website entry on the Poospatuck Res. marker.
The Unkechaug Indian Nation was recognized by the State of New York in 1777, a sovereign relationship which continues into 2019. This led to the creation of the Poospatuck Reservation, located one mile south at the Forge River and Poospatuck Creek. In Algonquian, Poospatuck translates to “where the waters meet” and Unkechaug translates to “people from beyond the hill.”
