Bald Eagle at Cushetunk Mountain


Cushetunk Mountain Preserve is part of a horseshoe-shaped mountain that was formed by volcanic activity during the Triassic Period 200 million years ago. The Lenni Lenape called this area “Cushetunk,” meaning “place of hogs,” due to the settlers’ hogs who at times escaped and roamed the mountains. Settlers simply called the area “Hog Mountain.”

Diabase rock made the area unsuitable for farming, so timber was the dominant early use.
The natural bowl formation of the valley led to the state’s selection of this site for the creation of the
Round Valley Reservoir in the 1960s. Ten homes in the valley were demolished and 16 others were relocated before the area was flooded. At a depth of 180 feet, the reservoir is the deepest body of water in NJ. In 1981, the county acquired 380 acres as open space.

Schick Farm PropertyBALD EAGLE INFORMATION The Cushetunk Mountain range has been home to a nesting pair of Bald Eagles for over 15 years. Bald Eagles are the county’s largest raptor, with a wingspan of seven to eight feet. The white head and tail do not develop until its fifth year. Fish are the staple of the eagles’ diet, but eagles are known to steal food from other raptors and scavenge off of carcasses.
Bald Eagle populations have grown since the banning of DDT and other pesticides, which once poisoned fish and accumulated in the eagles’ bodies. In 2007, Bald Eagles had recovered enough to be removed from the federal endangered species list, although they are still considered state endangered.

WILDLIFE AND HABITAT The preserve resides on the northern side of the Cushetunk Mountain. Since it is out of direct sunlight, the habitat is wetter then the southern side. Trees in in the park include chestnut oaks, tulip trees, beeches, and hickories. A variety of woodland birds can be seen or heard throughout the park, including warblers and thrushes in spring. Evidence of woodpeckers can be found on dying trees. Rocky outcroppings and moist seeps provide excellent habitat for reptiles and amphibians.
