Native American History Finds a New Home

Over 400 artifacts were uncovered by archaeologists prior to the construction of the Catskill/Delaware Ultraviolet Facility in Mount Pleasant and Greenburgh in Westchester County. These artifacts were given to the Historical Society Serving Sleepy Hollow and Tarrytown. Many of the unearthed objects date as far back as the late Archaic Era and early Woodland Period (ca. 5500-2800 BP)

The initial search of the parcel yielded two projectile points dating back as far as 2,800 years before present time.
