Physical Geography

Trenton, the capital city of New Jersey, is uniquely situated on the banks of the Delaware River. Its topography is marked by rolling hills and plateaus, with the land gradually sloping towards the riverfront. The city’s highest elevation, known as Prospect Hill, stands at 158 feet above sea level and offers panoramic views of the surrounding area. Trenton’s topography is shaped by its location within the Atlantic Coastal Plain, a vast geological region that extends from Massachusetts to Georgia.

Overlying the Lockatong Formation is the Brunswick Formation, a younger sequence of sedimentary rocks that includes sandstone, shale, and conglomerate. These formations have been subjected to millions of years of erosion, resulting in the formation of the rolling hills and plateaus that characterize Trenton’s landscape. Trenton’s riverfront is shaped by the erosive power of the Delaware River, which has carved a deep gorge into the underlying rock formations.
