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. The Navesink varies in depth from 45 feet (14 m) to 65 feet (20 m) across its range from Sandy Hook to Pennsville.
The Navesink has the highest radon gas potential of the New Jersey geologic 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. There is also exposure in Big Brook Park in Marlboro, NJ.
