The Big Brook site consisting of 143.44 acres, has been recognized by Federal, State and local environmental specialists as one of the most unique environmental areas both in Monmouth County and New Jersey. Its uniqueness includes being long recognized as a major site for fossils of both the Cretaceous and Pleistocene ages (70-65 million years old). Many school groups, elementary through college, currently visit the resource each year, thus providing both educational, as well as scientific benefits. Major fossil types found at the site include hundreds of specimens ranging from sharks teeth (relatively common) to rare Cretaceous marine reptiles and Ice Age mastodons. The site also includes large sections of green sand deposits, used as a natural fertilizer, which are fully exposed for study. In addition, numerous historic bottles, tools and farm implements dating from pre-revolutionary times to the early 20th century have been found in and around the Big Brook area. The site is also very aesthetic and awesome, with a wide variety of flora and fauna, as well as being transverse with the Big Brook stream. Parking is in the lot on Hillsdale Road or along Laurelwood Drive.
- Fossil Hunting
Big Brook Preserve is one of the few sites on the East Coast where fossils may be readily found. The area is noted for a variety of sharks teeth and other marine specimens. In recent years, the Big Brook site has been a concern to the Township in regard to the major increase in the use level of the resource. Due to a increase in the population of both Colts Neck and Monmouth County, plus the nature of the resource becoming known to more people within the New York Metropolitan Area, there has been increased usage by both individuals, schools and organized groups. The biggest concerns have been the type of excavation of the walls of the Big Brook stream bed, and the type of equipment used in the collection of fossils. As a result, it is now necessary to obtain a permit. The permit fee for groups of 15 - 29 people is $25.00; for use by groups of 30 people or more the permit fee is $50.00 and to adhere to the regulations posted at the entrance to the area. Groups of 14 or less do NOT require a permit. You may learn about the fossils at the Big Brook Identification Page. Permit requests may be sent via email to firstname.lastname@example.org BIG BROOK PRESERVE IS NOT LOCATED AT 14 HEYERS MILL ROAD
Equestrian Facilities Horses are welcome to share the hiking trails in Big Brook; however, detours around some of the smaller bridges will be necessary.
Hiking Trails The only formal development to date has been a hiking trail system maintained by a local Boy Scout troop. The trail runs along the brook from Laurelwood Drive to Hillsdale Road (1.25 miles one way) to Boundary Road (1/2 mile from Hillsdale Road).
Nature Studies Big Brook Preserve is in its natural state and contains several ecosystems including meadows, woods, stream area, and mashland. It is a good place for observing a variety of flora and fauna.
