Nearly 13,000 years ago, groups of hunter-gatherers entered the Musconetcong Valley. Near this location stood one of the most intensively revisited encampments of these early Native Americans, or Paleoindians, ever documented in New Jersey. Thousands of stone tools recovered from investigations at Plenge provide a unique record of human lifeways at the end of the last Ice Age and reveal how Native Americans adapted to a changing world.
