At the southern end of Secaucus is Snake Hill (officially known as Laurel Hill), an igneous rock diabase intrusion jutting up some 150 feet (46 m) from the Meadowlands below, near the New Jersey Turnpike.[38]
Being partly surrounded by the Hackensack Meadowlands, Secaucus provides opportunities to observe the recovery of natural marshes in the town’s post industrial, post agricultural age. Some marsh areas in the northeast part of town have been filled to provide a new commercial area, and some to build footpaths for nature walks with signs illustrating birds and other wildlife to be seen there.
