The Great Swamp was created approximately 15,000 years ago, when the melting waters of the Wisconsin Glacier poured into the natural basin known as the Passaic Valley. However, the Great Swamp is not entirely swampland but rather a mixture of marshes, meadows, dry woods and brush-covered swamps. It is the intermingling of these four habitats that gives the Great Swamp its unique character, allowing the swamp to support a wide variety of plant and animal life.
