The Arsenal is the headquarters of the US Army Combat Capabilities Development Command Armaments Center.

Four days later, it changed the name to Picatinny Powder Depot. In 1907, the Army altered the name to Picatinny Arsenal and established its first powder factory on the site." The facility was founded in 1880 as the Picatinny Powder Depot. Soon afterward, the Navy acquired a portion of the arsenal to establish the Lake Denmark Powder Depot, later known as Lake Denmark Naval Ammunition Depot. It manufactured gunpowder until after World War I, at which time the facility also began producing heavy munitions and grew more involved in research and development activities. During World War II Picatinny was a major large-caliber-round loading plant with 18,000 employees. Today, the facility develops new technologies for the US Armed Forces and builds various munitions, weapons and armor systems. Picatinny Arsenal is also home to the US Army Explosive Ordnance Disposal Technology Directorate. This group is responsible for the creation of tools, equipment, and procedures for US Army EOD personnel. Some of their more recent inventions were the use of weapons on a robot platform and the SWORDS robot. Their building has been recently renamed in honor of one of their deceased soldiers, SFC Scott "Smitty" Smith, who was killed in Iraq in July 2006.

Lake Shawnee is a small 83-acre (34 ha) private Lake located in Jefferson Township, New Jersey, United States. Its outsourcing is Beaver Brook, which flows into Lake Hopatcong, New Jersey's largest lake. Lake Shawnee and its watershed are the headwaters of the Musconetcong River watershed. The Lake Shawnee Reservation, as it is known, was developed in 1946 by the Arthur D. Crane Company of Sparta, real estate developers, which incorporated the Lake Shawnee Club and began selling home sites on the Lake many of which were originally summer homes. By 1948, the first two homes were built and during the next 15 years the Club reached its peak of 562 resident members. The clubhouse was then constructed and First Beach, not included in the original deeds, was subsequently purchased from the Crane Company with funds raised from within the membership. Carl Peterson was instrumental in developing the Third Beach area and was known as Mr. Shawnee among local residents.The Lake Shawnee dam was damaged during a storm in March 2010. The dam had already been under pressure by a snowy winter, causing rising water levels.In 2016, there was an effort to change the mailing address from a Wharton, New Jersey 07885 ZIP code, to a Lake Hopatcong 07849 ZIP code. The effort was narrowly defeated. In 2026, a new effort will be made to change the mailing address ZIP code to 07849.

The New York – New Jersey Highlands is a geological formation composed primarily of Precambrian igneous and metamorphic rock running from the Delaware River near Musconetcong Mountain, northeast through the Skylands Region of New Jersey along the Bearfort Ridge and the Ramapo Mountains, Sterling Forest, Harriman and Bear Mountain State Parks in New York, to the Hudson River at Storm King Mountain. The northern region is also known as the Hudson Highlands and the southern as the New Jersey Highlands. A broader definition would extend the region west to Reading, Pennsylvania, and east to the Housatonic River in Connecticut, encompassing the Reading Prong. The highlands are a subrange of the Appalachian Mountains. In New Jersey, the region's watershed is protected by the state's own Highlands Water Protection and Planning Act (2004). In addition to preserving water resources, the act created the New Jersey Highlands Water Protection and Planning Council (NJ Highlands Council) whose mission includes supporting open space preservation and the creation of new recreational parks and hiking trails in America's most densely populated state. These include the Highlands Trail, designated as a Millennium Trail by the White House Millennium Council and maintained by the New York-New Jersey Trail Conference. The New Jersey Highlands Coalition was formed in 1988 to protect the resources of the region.In November 2004, the federal Highlands Conservation Act was passed. The Highlands Conservation Act “recognizes the importance of the water, forest, agricultural, wildlife, recreational, and cultural resources of the Highlands region, and the national significance of the Highlands region to the United States.”

The Hibernia mines are a series of iron mines in and around Rockaway Township, in Morris County, New Jersey, United States, that were worked from pre-Revolutionary times until 1916. The mines worked a vein extending for more than two miles (3.2 km). Several companies operated mines in the area. An adit was constructed into the Hibernia hill to move ore to the railhead of the Hibernia Railroad. Ore in excess of 90,000 short tons (82,000 t) was shipped in 1879.An exploratory shaft was drilled in the 1950s but was not worked, and the shafts and adit were partly or totally sealed in 1972 and 1989. After its closure, the mine became the largest bat hibernaculum in New Jersey, with as many 30,000 bats each winter. In 2010, less than 10% that number was found in the mine following an outbreak of white nose syndrome.
