SOUTH MOUNTAIN RESERVATION
Millburn/West Orange/Maplewood, Essex County, NJ
This is a 2,048 acre park, largest park in Essex County, with nineteen miles of trails. The park is located between the First and Second Watchungs, these serving as boundaries of the park.
Park at the Locust Grove parking and picnic area opposite the railroad station in downtown Take exit 10 (Northfield Avenue) off of I-280 to Mount Pleasant Avenue. Turn south, following Gregory Avenue, Wyoming Avenue, South Wyoming Avenue, Sagamore Road, and Glen Road and turn right in Millburn (near the Paper Mill Playhouse) off the Glen Avenue-Lackawanna Place intersection at the wooded sign.
Basalt lava flows in this rift valley (Newark Basin, Piedmont). Look for turtle backs, which were formed when the basaltic traprock fractured into small hexagonal blocks. Minerals filled in the cracks, then erosion wore away the basalt faster than the minerals. The resulting pattern was rock similar to the back of a turtle.
West Branch of the Rahway River heads south through the park flowing through Orange Reservoir, Campbells Pond and Diamond Mill Pond.
The presence of the early Lenape Indians lingers in the name given to the Watchung--the "high hills."
1616 -- first settlers arrived in Newark and stripped the forest of hemlock and white pine in order to build their houses.
Revolutionary War -- Beacon Signal Station 9 was located here--one of 23 beacons built by General Washington to observe British troop movements quartered on Staten Island and New York City. It was from this outlook that, on June 23, 1780, Essex County and Newark Militia were first warned that the British had launched an attack westward toward "the Gap," (Hobart Gap), a natural pathway to Washington's troops encamped at Morris Town. In a pincer movement designed to gain access to the Gap, Hessian troops fought bitterly along Vaux Hall Road, with the British advanced along Galloping Hill Road until they were repelled, the Hessians at the base of the mountain and the British in Millburn--called Millville in those days. Legend has it that General George Washington monitored the battle from what is now Washington Rock.
late 1700s -- when the demand for lumber had lessened, paper mills took the place of sawmills, and now the second-growth forest was ravaged. Scottish immigrant Samuel Campbell, for whom Campbell's Pond is named, was the first to build a mill; he produced paper used to print money for the U.S. government. Today, the Diamond Papermill Company is the Paper Mill Playhouse.
War of 1812 -- Washington Rock served again as a lookout for the Army.
1895 -- the park was built from land purchases begun this year, the first year of the Park Commission's life. It took a decade to untangle the deeds and assemble all the lands at South Mountain.
Frederick Law Olmsted (designer of New York City's Central Park) designed South Mountain Reservation. Before he delegated design of the Essex Parks to his stepson's firm, Frederick Law Olmsted visited the newly acquired reservation. He regarded it as some of the most beautiful and promising terrain he had ever seen anywhere. The design of South Mountain was finalized by the Olmsted Brothers in stages over the years.
beginning of the 20th century -- The Essex County Park Commission took over the area in order to protect it from the damage done by logging and paper mill companies.
1908 -- a covered, open-air shelter of chestnut logs was built. Today, just beyond Washington's Rock, the only remnant is a flat concrete platform.
1910 -- more than 3000 rhododendrons were planted. Hemlock, pine, mountain laurel and wild azalea were also planted.
1934 -- A good deal of construction work--trails, foot bridges, shelters, etc.--was carried out by the Civilian Conservation Corps.
There was a major planting of cherry trees in South Mountain Reservation.

The vistas of New York, Elizabeth, Union, Staten Island, and Newark can be viewed from the eastern ridge, 550 feet above the community of Millburn. Deep in the woods a 25-foot waterfall at Hemlock Falls is a dramatic feature. The roadway on Crest Drive has been closed to vehicular traffic at the old deer paddock so that you may enjoy a leisurely walk down to Washington Rock.
You can travel clockwise on the yellow blazed Lenape trail heading northeast then north; northwest, southwest and south back to the parking area. At the end of Crest Drive is a great viewing place overlooking I-78 which is the pass through which the ancient Passaic River once flowed. During the Revolutionary War, the British tried to march on Washington's encampment near Morristown. Washington Rock has a plaque which tells about the events. The British burned Connecticut Farms (now called Union) and Springfield. There was a sentry at Washington Rock. If the sentries saw British troops, they would start a bonfire to alert the Americans encamped at Jockey Hollow. From here you can see over Millburn, Springfield, and toward the ridge where the Watchung Reservation is located. The tower on the ridge to the right is the Bell Telephone building.
You climb upwards. One place you go by is Washington Rock. Along the way you pass Maple Falls Cascade, a 25-foot drop over basalt. Then comes Beech Brook Cascade followed by Hemlock Falls (a popular picnic spot close to South Orange Avenue).
You abandon the yellow trail when it turns right in favor of going straight across the intersection. You should cross the Rahway River and follow the white-blazed Rahway Trail paralleling the river. The Rahway Trail will go south following the east bank of the Rahway Riverback to the parking lot.
You can go in a figure-eight. The short version is the bottom half of the figure eight. In the northern part of the park was Mayapple Hill and Turtleback Rock. Take the Lenape Trail (yellow) out to the Oakdale Trail (red) and head back on the Lenape Trail (yellow) and the Cascade Trail (yellow).

Near the northern end of the reservation is Turtle Back Zoo (560 Northfield Avenue, West Orange 07052). The zoo, located on 16 acres, houses 500 animals of 200 different species. The emphas is on animals of New Jersey.

The reservation has changed only slightly through the years. It's been preserved primarily in its wild state. Woodlands abound in a variety of hardwood trees, and tall hemlocks tower above streams, creeks and ponds.

April 12, 1930
Spring flowers were found to be late in bloom, on the joint excursion of the TBC and the NY "Section of the Green Mountain Club, in the South Mountain Reservation of the Essex County Park system, on Saturday, April 12, 1930.
Apparently cool weather had slowed up the progress of vegetation; the woods were still mostly brown and bare, but along the streams, some greenery was afforded by the skunk cabbage and green hellebore. Spice bush was only beginning to bloom in a few sunny spots. A few hepaticas were found in blossom.
However, in the absence of blooming plants, the party of 29, under the leadership of Mr. Andrew Scarlett of South Orange, NJ found several objects of geological interest. Chief among these was the Turtle Back Rocks, on First Watchung Mountain, near Northfield Avenue, a striking example of incipient columnar formation in basalt. Boulders containing marine shell casts, from the Silurian formations of the Upper Hudson Valley, were found in glacial gravel in a pit, south of the Orange Reservoir. Fresh exposures of the columnar basalt in a quarry west of South Orange, were also of interest.
