Glacial Rock

 Glacial Rocks


This nature trail is located in the Piedmont Physiographic Province. About 10,000 years ago, the Great Wisconsin Glacier made its way to the Edison/Metuchen area. As the Glacier retreated and melted, it left a large amount of debris. This may account for the rolling and uneven topography of the trail. This debris is known as Terminal Moraine. Moraine is the accumulation of glacial debris. The debris may have been taken from a valley floor as the Glacier advanced or it may have fallen off valley walls as a result of frost wedging or landslide. The debris ranges from small rocks to large boulders. Next to this trail sign, you will see one of the few glacial rocks scattered throughout the nature trail.
