End-Sheets NJ State Parks Adopt a Crag 2 www.climbnj.com CRI 2007 Access NJ Introduction In a State known for its beaches, meadowlands and malls, rock climbing is a well established year-round, outdoor, all weather recreational activity. Rock Climbing “cragging” (A rock-climbers' term for a cliff or group of cliffs, in any location, which is or may be suitable for climbing) in NJ is limited by access. Climbing access in NJ is constrained by topography, weather, the environment and other variables. Climbing encounters access issues . with private landowners, municipalities, State and Federal Governments, watershed authorities and other landowners and managers of the States natural resources. The motives and impacts of climbers are not distinct from hikers, bikers, nor others who use NJ's open space areas. Climbers like these others, seek urban escape, nature appreciation, wildlife observation, exercise and a variety of other enriching outcomes when we use the resources of the New Jersey’s State Parks and Forests (Steve Matous, Access Fund Director, March 2004). -

Land, Natural Resources, and Geology
Land and Natural Resources of West Amwell By Fred Bowers, Ph.D Goat Hill from the north Diabase Boulders are common. Shale and Argillite outcrops appear like this. General Description of the Area West Amwell Township is in Hunterdon County, New Jersey, USA. It is a 22 square mile rural township with just over 2200 people, located near Lambertville, New Jersey. It is one of the more scenic parts of the New Jersey Piedmont. It is identified in red on the maps below. West Amwell is characterized by most people as a "rocky land." One of the oldest villages in the township is called Rocktown. If you visit or look around the township, you cannot avoid seeing rocks and outcrops like those pictured above. Hunterdon County New Jersey, with West Amwell located at the southern border, marked in red The physiographic provinces of New Jersey, with Hunterdon County and West Amwell marked in red Rocks The backbone of West Amwell Township's land is the Sourland Mountain; a typical Piedmont ridge formed by a very hard igneous rock called diabase or "Trap Rock." The Sourland Mountain ends at the Delaware River below Goat Hill which you see in the picture above, looking south from the Lambertville toll bridge. To the south and north of the diabase, shale and argillite occurs, and these rocks form the lower lands we know of as Pleasant Valley and the shale ridges and valleys you see from around Mt. Airy. In order to appreciate the rocks and the influence they have on the look of the land, it is useful to have a short review of rocks. -
Flat Rock Brook” This Stream Flows Downhill Over the Eroded Flat Surfaces of the Diabase Basalt Forming the Palisades
“Flat Rock Brook” This stream flows downhill over the eroded flat surfaces of the diabase basalt forming the Palisades. It drains into Crystal Lake and Overpeck Creek as part of the Hackensack River watershed. Flat Rock Brook flows down from the top of the Palisades beginning in Englewood Cliffs The brook empties into Crystal Lake and now continues in culverts beneath Interstate 80/95 to Overpeck Creek, a tributary of the Hackensack River watershed. The “flat rocks” are diabase basalts at the top of an igneous intrusion, the Palisades Sill. (See “The Seven Sisters” for more information.) They formed underground about 200 million years ago. The diabase was more resistant to erosion than the overlying sedimentary rocks. Over time, the overlying rocks were removed by erosion, exposing the flat diabase surface. Earthquakes tilted the region, producing the westward slope characterizing the East Hill section of Englewood down to Grand Ave. and Engle St. On the eastern side of the sill, erosion and rock falls created the cliffs of the Palisades along the Hudson River. This 1880s map shows part of Flat Rock Brook. The pond labelled “Vanderbeck’s Mill Pond” was created by damming the brook in 1876. It was later known as Macfadden’s Pond. https://www.flatrockbrook.org/about-us/history In the 1970s, the Englewood Nature Association (now the Flat Rock Brook Nature Association) was established to preserve the area, resulting in establishment of the Flat Rock Brook Nature Center. Green Acres funding from the State of New Jersey was important in beginning this project. In the 1980s, it was merged with Allison Park, creating the 150-acre preserve in existence today. -

Observations and Tectonic Setting of Historic and Instrumentally Located Earthquakes in the Greater New York City–Philadelphia Area by Lynn R
Bulletin of the Seismological Society of America, Vol. 98, No. 4, pp. 1696–1719, August 2008, doi: 10.1785/0120070167 Ⓔ Observations and Tectonic Setting of Historic and Instrumentally Located Earthquakes in the Greater New York City–Philadelphia Area by Lynn R. Sykes, John G. Armbruster, Won-Young Kim, and Leonardo Seeber Abstract A catalog of 383 earthquakes in southeastern New York, southwestern Connecticut, northern New Jersey, and eastern Pennsylvania, including metropolitan New York City and Philadelphia, is compiled from historical and instrumental data from 1677 through 2006. A magnitude-felt area relationship is used to calculate the equivalent magnitude mbLg prior to the advent of abundant instrumental data in 1974. Revised locations are computed for a number of historic earthquakes. Most hypo- centers are concentrated in older terranes bordering the Mesozoic Newark basin in the Reading, Manhattan, and Trenton prongs and in similar rocks found at a shallow depth beneath the coastal plain from south of New York City across central New Jersey. Historic shocks of mbLg 3 and larger were most numerous in the latter zone. The largest known event, mbLg 5.25, occurred just offshore of New York City in 1884. Many earthquakes have occurred beneath the 12-km wide Ramapo seismic zone (RSZ) in the eastern part of the Reading prong, where station coverage was the most ex- tensive since 1974. The southeastern boundary of the RSZ, which is nearly vertical, extends from near the surface trace of the Mesozoic Ramapo fault to depths of 12–15 km. Because the Mesozoic border fault dips about 50°–60° southeast, earth- quakes of the RSZ are occurring within middle Proterozoic through early Paleozoic rocks. -

Early Residents Gave the Nickname “The Seven Sisters” to the Slopes and Flat Areas Between Them, Especially on Palisade Ave
“The Seven Sisters” Palisades Diabase bedrock These slopes and flatter areas underlain by diabase bedrock on the west side of the Palisades were nicknamed “The Seven Sisters” by early residents. Early residents gave the nickname “The Seven Sisters” to the slopes and flat areas between them, especially on Palisade Ave. The solid bedrock that forms the Palisades cliffs along the Hudson River and the sloping hills on the eastern side of Englewood and vicinity are composed of diabase basalt. This dark-colored igneous rock (Fig. 1) was created about 200 million years ago as part of the Late Triassic-Early Jurassic Newark Basin. (See “Bedrock Geology.”) Magma rose from a deep source of molten material but was forced to flow horizontally underground between layers of the older sedimentary rocks, rather than reach the surface. Later, regional earthquake activity tilted the layers downward to the west, and erosion removed most of the overlying softer sedimentary rocks to expose the harder diabase basalt (Fig. 2). Fig. 1. Diabase (credit: https://en.wikipedia.org/wiki/Diabase) Fig. 2. The “Seven Sisters” formed on the sloping upper surface of the Palisades Sill (TRps). It originally formed beneath the overlying sedimentary rocks (TRn), but was exposed as these were eroded. The whole region was tilted downward to the west. (https://en.wikipedia.org/wiki/Palisades_Sill) Credit: http://stevekluge.com/geoscience/images/palisades/default.html What is now Palisade Avenue was originally constructed as a logging road to bring cut timber down the hill to where the Northern Railroad was being constructed. It was a dirt road that ran directly from the top of the Palisades to Overpeck Creek. -
