Page "Parsippany-Troy Hills, New Jersey" Paragraph 10

After the Wisconsin Glacier melted around 13, 000 BC, half of Parsippany was filled with water as this was Lake Passaic.

Around the area grasses grew as the area was tundra and then turned into a taiga / boreal forest as the area warmed.

Paleo Indians moved in small groups into the area around 12, 500 years ago, attracted by the diversity of plant and animal life.

Native Americans settled into the area several thousand years ago, dwelling in the highlands and along the Rockaway River and the Whippany River, where they hunted and fished for the various game that lived in the area and migrated through the area in autumn.

Paintings in a rock cave were found in the late 1970s in western Parsippany in the highlands.
