The Ramapough Mountain Indians, known also as the Ramapough Lenape Nation or Ramapough Lunaape Munsee Delaware Nation or Ramapo Mountain people, are a New Jersey state-recognized tribe based in Mahwah. They have approximately 5,000 members living in and around the Ramapo Mountains of Bergen and Passaic counties in northern New Jersey and Rockland County in southern New York, about 25 miles (40 km) from New York City.
Lake Passaic was a prehistoric proglacial lake that existed in northern New Jersey in the United States at the end of the last ice age approximately 19,000–14,000 years ago. The lake was formed of waters released by the retreating Wisconsin Glacier, which had pushed large quantities of earth and rock ahead of its advance, blocking the previous natural drainage of the ancestral Passaic River through a gap in the central Watchung Mountains. The lake persisted for several thousand years as melting ice and eroding moraine dams slowly drained the former lake basin. The effect of the lake's creation permanently altered the course of the Passaic River, forcing it to take a circuitous route through the northern Watchung Mountains before spilling out into the lower piedmont.
The Watchung Mountains are a group of three long low ridges of volcanic origin, between 400 and 500 feet high, lying parallel to each other in northern New Jersey in the United States. The name is derived from the American Native Lenape name for them, Wach Unks. In the 18th century, the Euro-American settlers also called them the Blue Mountains or Blue Hills. The Watchung Mountains are known for their numerous scenic vistas overlooking the skylines of New York City and Newark, New Jersey, as well as their isolated ecosystems containing rare plants, endangered wildlife, rich minerals, and globally imperiled trap rock glade communities. The ridges traditionally contained the westward spread of urbanization, forming a significant geologic barrier beyond the piedmont west of the Hudson River; the town of Newark, for example, once included lands from the Hudson to the base of the mountains. Later treaties moved the boundary to the top of the mountain, to include the springs.
The Ramapo River is a tributary of the Pompton River, approximately 30 mi (48 km) long, in southern New York and northern New Jersey in the United States.
Ramapo Mountain State Forest is a 4,200-acre (17 km2) state forest in Bergen and Passaic Counties in New Jersey. The park is operated and maintained by the New Jersey Division of Parks and Forestry.
Goffle Brook is a tributary of the Passaic River which flows south through a section of Passaic County and Bergen County in New Jersey and drains the eastern side of the First Watchung Mountain. Heading up the brook from the confluence with the Passaic River, one encounters the borough of Hawthorne, the village of Ridgewood, the borough of Midland Park, and the township of Wyckoff.
Houvenkopf or Hovenkopf Mountain is a mountain in Bergen County, New Jersey. It extends into New York, where it forms the western side of the southern entrance to Ramapo Pass. The major peak on the New Jersey side rises to 931 feet (284 m) and is known as Stag Hill. It is separated by a deep saddle from the major peak on the New York side known as the Hooge Kop proper, which rises to about 770 feet (230 m). Houvenkopf Mountain is located in Mahwah, New Jersey and overlooks Hillburn to the north, Suffern to the east, and Ringwood, New Jersey to the west. It is part of the Ramapo Mountains.
Sourland Mountain is a 17 miles (27 km) long ridge in central New Jersey, U.S., extending from the Delaware River at Lambertville to the western end of Hillsborough Township near the community of Neshanic, through Montgomery Township and into Hopewell Township in Mercer County. It comprises the largest contiguous forest in Central Jersey, nearly 90 square miles (233 km2) in area. The highest point is only 568 feet (173 m) above sea level, but the way it rises steeply from the surrounding farmland has earned it the title of 'mountain'. The ridge itself sits within a larger area of rough terrain called The Sourlands.
Watchung Reservation is the largest nature reserve in Union County, New Jersey, United States. The Watchung area is located on a ridge within northern-central New Jersey, as it consists mainly of the upper valley of Blue Brook, between the ridges of the First Watchung Mountain and Second Watchung Mountains. A dam near the headwaters of the creek creates Lake Surprise.
Cushetunk Mountain is a ring shaped mountain in the U.S. state of New Jersey, located in Readington and Clinton Township in Hunterdon County. The Lenape Native Americans called the mountain "Cushetunk" meaning "place of hogs" after the wild hogs found there. In the 1960s, the valley at the heart of the mountain was dammed and filled with water to create Round Valley Reservoir. Today, the mountain and its accompanying lake act as a vital water supply to Central New Jersey, while at the same time providing numerous recreational opportunities to the region.
Campgaw Mountain Reservation is a 1351-acre (5.5 km2) county park of Bergen County, New Jersey. It is located mostly within Mahwah, but extends into the northeastern part of Oakland, as well as the northwestern part of Franklin Lakes. The park includes a ski area and the peak of Campgaw Mountain at a 735-foot (224 m) elevation.
The Lenape Trail is a trail through Essex County, connecting many county parks and reservations, wooded spaces, and historical sites. It begins in Newark, New Jersey and ends in Millburn, New Jersey. It was established in 1982. It is the fifth longest trail in the state behind the Delaware and Raritan Canal Trail, the Appalachian Trail, the completed section of the Highlands Trail in the state and the Batona Trail. The Lenape trail traverses Newark and its suburbs, as well as the Watchung Mountains and Passaic Meadows. Because of the steepness of the Watchung Mountains and the flood-prone nature of the Passaic Meadows, the former basin of Glacial Lake Passaic, these areas have remained much less developed than the rest of the northeastern part of the state. This trail therefore offers hikers an opportunity to see cultural and historical sites of an urban trail, as well as large natural and undeveloped areas. The trail's proximity to New York City and the various ridges it traverses, including Forest Hill, Orange Mountain, and Second Watchung Mountain, offer many views of the skyline. The Lenape Trail forms a segment of the Liberty-Water Gap Trail and incorporates the West Essex Trail, the Lenape Trail's only rail-to-trail section. The Lenape Trail also connects with Morris County's Patriots Path trail system on its western terminus.
Goffle Brook Park is a public, county park spanning much of the length of Goffle Brook through the borough of Hawthorne in Passaic County, New Jersey, United States. Since its designation and construction between 1930 and 1932, the park has served to protect the waters of Goffle Brook while at the same time providing recreational opportunities to the residents of Passaic County and nearby Bergen County. Goffle Brook Park has been included in the National Register of Historic Places since 2002.
The Preakness Range is a range of the trap rock Watchung Mountains on the western edge of the Newark Basin in northern New Jersey. A large portion of this range is included in High Mountain Park Preserve, offering miles of hiking trails with vistas overlooking New Jersey and New York City. The peaks of the Preakness Range, the highest of the Watchung Mountains, shelter endangered ecosystems, including perched wetlands and rare trap rock glade communities.
Goffle Hill, also referred to as Goffle Mountain and historically known as Totoway Mountain and Wagaraw Mountain, is a range of the trap rock Watchung Mountains on the western edge of the Newark Basin in northern New Jersey. The hill straddles part of the border of Bergen County and Passaic County, underlying a mostly suburban setting. While hosting patches of woodlands, perched wetlands, and traprock glades, the hill is largely unprotected from development. Extensive quarrying for trap rock has obliterated large tracts of the hill in North Haledon, and Prospect Park. Conservation efforts seeking to preserve undeveloped land, such as the local Save the Woods initiative (2007–present), are ongoing.
The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps the best known fault zone in the Mid-Atlantic region, and some small earthquakes have been known to occur in its vicinity. Recently, public knowledge about the fault has increased, especially after the 1970s, when the fault's proximity to the Indian Point nuclear plant in New York was noted.
The Towaco Formation is a mapped bedrock unit in New Jersey. It is named for the unincorporated village of Towaco, which is near the place its type section was described by paleontologist Paul E. Olsen.
The Feltville Formation is a mapped bedrock unit primarily in New Jersey, with one known outlier in Pennsylvania and another one in New York. It is named for the Deserted Village of Feltville in Watchung Reservation, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen.
The Watchung Outliers include six areas of isolated low hills and rock outcrops of volcanic and sedimentary origin in the U.S. states of New York, New Jersey, and Pennsylvania. These geologic outliers are primarily diminutive and detached remnants of the Triassic/Jurassic age Watchung Mountain basalt flows with intervening layers of sedimentary rock. All six of the outliers are found along the western edge of the Newark Basin, occupying small synclines adjacent to the Ramapo fault system. The outliers, from north to south, are known as: Ladentown, Union Hill, New Germantown/Oldwick, Prospect Hill, Sand Brook, and Jacksonwald.
