Mineral Collecting in North Jersey

Just in North Jersey alone, there are many recognized mineral collecting locations, some accessible, some not, and there are several localities which are world famous for their variety and quality of mineral species found. In fact, one area, the Franklin-Ogdensburg district in Sussex County boasts more minerals in one single location than any other spot on earth. Below is a map of documented mineral locations in North Jersey and surrounding nearby localities and what each location is best known for. Some of the sites are no longer accessible, some require a fee to be paid, some require permission from property owners, and a few are still open to the public. Always check into the status of a particular site and obtain necessary permission before attempting to collect there.

Fossil Collecting in New Jersey

Fossil sites are not nearly as plentiful in New Jersey. In fact, in the northern 2/3 of the state, only a few sites produce fossils of any kind. Those sites include:

F1 - Trilobite Ridge(Montague)<devonian-age marine fossils; trilobites, brachiopods, gastropods, crinoids>
F2 - Dino Track Site(Clifton)<fossilized dinosaur tracks - site now closed>
F3 - Big Brook, Ramenessen Brook(Freehold)<fossilized sharks teeth and marine fossils>
F4 - Poricy Park(Middletown)<ass't marine fossils and shark teeth>
F9 - Stromatolite Exposure (Hamburg) <World-renowned exposure of Stromatolites and well-preserved Oolites(NO collecting)>
