Clinton and Readington townships, Lebanon, Hunterdon County, NJ
336 acres


It is located off Route 31, south of Route 78. The upper portions adjoin Round Valley Recreation Area.

New Jersey Turnpike to exit 14 for Newark Airport; US 78 to the exit 20A; the exit leads directly south on Cokesbury Road; go .3 miles and left turn onto Main Street (Route 622); go .15 miles and right turn onto Route 629 Cherry Street; go .45 miles and turn left onto Old Mountain Road (just before the fence for the dam at Round Valley Reservoir) and go 1.7 miles and turn right into the park entrance (just before the railroad tracks and Railroad Avenue).


The Raritan Valley is east of the Hunterdon Plateau. It is a low rolling plain, sloping gently southeastward from an elevation of 200-300 feet near the plateau to 100-200 feet near the Hunterdon- Somerset County border. A number of ridges and isolated hills, underlain by highly resistant igneous rock, rise several hundred feet above the softer shale and sandstone of the Raritan-Valley Lowland. The highest of these ridges, Cushetunk Mountain rises about 500 feet above the plain and 834 feet above sea level.

Diabase is exposed in the Watchung Mountains in adjacent Somerset County. It can also be seen at Sourland and Cushetunk Mountains (Round Valley). The crystal structure of diabase indicates that the rocks never reached the surface at the time of formation and their exposure today is the result of erosion. (Information from HUNTERDON COUNTY GEOLOGY by Carol S. Lucey - New Jersey State Geologist)


Cushetunk means Gosch-gosch, "hog" and unk, "place," or "place of hogs" because of the wild hogs that roamed the mountains.

The early settlers called the area "Hog Mountain".


currently undeveloped? It looks alright to me. There is a power cut along the base of the mountain.


Basalt rock. Newark Basin (Piedmont).


There is a temporary closing of one of the paths up to the top of Cushetunk Mountain.

Another, however, is open. Mountain bikes are allowed and when we were there, we saw quite a few bikers.

We mostly investigated the power cut as we too tired by this time to climb the mountain.

The main trail up the mountain is closed but the bikers have made quite a few other informal trails. The second time I came to Cushetunk I hiked up the mountain. It is mostly just forest up there -- no dry clearings as on the tops of many other mountains. I did think that I saw an eagle flying up there squeaking like a heavy door partly swing closed.

Hunting permitted October 1 to January 31.

David Snyder reports Viola hirsutula is here. He says it is one of the more distinctive stemless blue violets occurring in NJ, differing from all others in its thickish, round-ovate leaves that lie flat on the ground and form a small rosette (a southern species).


The weather was absolutely beautiful and nearly every great regularly-attending Torrey field botanist in the northern half of New Jersey showed up for this walk. The trails directly to the top were closed, but there was still a great number of interesting plants to be seen.

The highlight in the fields surrounding Cushetunk Mountain was Lilium canadense (wild yellow lily). Some of the other field plants in bloom included Achillea millefolium, Allium vineale, Anthemis cotula, Asclepias tuberosa, Barbarea vulgaris, Ceanothus americanus, Chrysanthemum leucanthemum, Cichorium intybus, Cirsium arvense, Dianthus armeria, Erigeron annuus, Galium mollugo, Hypericum perforatum and H. punctatum, Lobelia spicata, Lonicera japonica, Lotus corniculatus, Medicago lupulina, Melilotus officinalis, Plantago lanceolata, P. major, and P. rugelii, Polygonum scandens, Pycnanthemum virginianum and P. tenuifolium, Raphanus raphanistrum, Rosa palustris, Rubus odoratus, Rudbeckia hirta var. pulcherrima, Sisyrinchium angustifolium, Trifolium aureum, T. hybridum, T. pratense, and T. repens, and Vicia tetrasperma. A non-blooming species of interest in the field was the thimbleweed (Anemone virginiana). Blooming in and near a dried up ditch along the railroad tracks were Anagallis arvensis and Veronica anagallis-aquatica.

The really great treat in the woods was the fantastic number of blooms of Cimicifuga racemosa (bugbane or black cohosh). Other interesting blooms in the forest included Agrimonia gryposepala, Asclepias exaltata, Chimaphila maculata, Circaea lutetiana, Desmodium glutinosum, Galium circaezens, Geum canadense, Pyrola elliptica, Sanicula canadensis, and Silene stellata. Other interesting plants were Chrysosplenium americanum, Corylus cornuta, Orchis spectabilis, and Staphylea trifolia.

Among the sedges found in the very scarce wet areas included Carex gynandra, C. lurida, C. scoparia, and C. vulpinoidea var. ambigua. Some of the plants in bloom in and around these areas were Impatiens capensis, Ludwigia alternifolia, Lysimachia ciliata, Mimulus ringens, Myosotis laxa, and Sambucus canadensis.

Total attendance was 17 humans and 2 dogs (Snuffy and Libby). Thanks to so many of the wonderful field botanists in attendance including Karl Anderson, John Medallis, Dr. Mary and Charles Leck, Robert Maricic, Charlotte Newstead, Elizabeth Scott, and Dr. William F. Standaert. Thanks also to Dr. Standaert for preparing the trip plant list.
