Description

The Navesink formation, named after Navesink, New Jersey, is typically found above the Mount Laurel Formation and under the Red Bank Formation. There is a 5 mya gap between the Navesink and Mount Laurel Formations.[2] The Navesink varies in depth from 45 feet (14 m) to 65 feet (20 m) across its range from Sandy Hook to Pennsville.[3][4]

The Navesink has the highest radon gas potential of the New Jersey geologic[5] formations.

Sites

There are several locations where the Navesink formation is visible including Poricy Park in Middletown, New Jersey which has several exposures along Poricy Brook.
