Sterling Forest, New York is a hamlet in the Town of Warwick, Orange County. It is served by an active United States post office of the same name. It is situated on the eastern shore of Greenwood Lake, at the New Jersey state line. Part of the hamlet extends into West Milford Township, Passaic County, New Jersey. The hamlet grew up around the terminal station of the Montclair and Greenwood Lake Railway, later called the New York and Greenwood Lake Railway, and later the Greenwood Lake division of the Erie Railroad. The railroad reached this point around 1875, with the station located at the state line in New Jersey. The depot complex originally contained the Sterling Forest, New Jersey post office. The post office was moved to the New York side of the line in 1926, where it continues to operate. Rail service ceased in 1935. The coming of the railroad was preceded by the construction of a large commercial ice house by the Ringwood Company around 1864. The Sterling Forest ice house was later operated by the Mountain Ice Company of Hoboken, New Jersey. It ceased operation and was eventually torn down in 1945. At one time, the hamlet also boasted two hotels (one in New Jersey), a general store, lumber yard, two bars (in addition to those in the hotels) and a Roman Catholic church (in New Jersey). Today, the only businesses that remain are one bar/restaurant, and a marina (on the site of the depot). In the 1930s and 1940s, Yankee great Babe Ruth often rented a cabin in the hamlet for the summer, and was known to play baseball with the local neighborhood children at a small ballfield located there. It was the site of the first American rocket airplane flight that carried mail from the New York side of the state line to the New Jersey side on February 23, 1936. Often confused with Sterling Forest, New York is the old Sterling Forest Gardens property and the adjacent Sterling Forest State Park, both located several miles away in the Town of Tuxedo, New York. The property is now the site of the New York Renaissance Faire, an annual Renaissance fair. Adding to the confusion, there is another fair called The Sterling Renaissance Festival which is located north of Syracuse, NY.

The Ringwood Mines landfill site is a 500 acres (200 ha) former iron mining site located in the borough of Ringwood, New Jersey. From 1967 to 1980, the Ford Motor Company dumped hazardous waste on this land, which negatively affected the health and properties of Ramapough Mountain Indians. This led to Mann V. Ford, a 1997 lawsuit between Ramapough Lenape Tribe's lawsuit of the Ford Motor Company. Used in the late 1960s and early 1970s by the large Ford Motor Company plant in nearby Mahwah, New Jersey for disposal of waste, it was identified by the Environmental Protection Agency (EPA) for its Superfund priority list in 1984 for cleanup of hazardous wastes. EPA deleted the site from the Superfund list in 1994 but subsequently relisted the site several times due to failed environmental remediation. Portions of the landfill site were repurposed as land used for affordable housing for the Ramapough people in the 1970s, even though the land was contaminated. The plant closed in 1980. EPA found additional pockets of paint sludge in 1995, 1998 and in 2004; it directed Ford to do additional cleanup. In 2005, the Bergen Record did a five-part investigative series, Toxic Legacy, on the site and found extensive contamination in the nearby residential community. EPA confirmed the area was contaminated with industrial and hazardous waste and placed the site back on the Superfund priority list in 2006. It is part of the watershed for 2.5 million people in New Jersey. Part of the 500 acres (200 ha) site extends into Ringwood State Park, as Ford had donated five acres of the former Peters Mine Pit site to the state, which absorbed it into the park. By 2011, an additional 47,000 tonnes (104,000,000 lb) of contaminated earth has been removed from the site, five times as much as had been removed under the earlier cleanup in the 1980s and 1990s.

Blue Lake, also called Sterling Forest Lake, is a lake located in Sterling Forest State Park, New York. As of 2018, the Blue Lake Reservoir System, operated by SUEZ North America (formerly United Water), supplies drinking water from Blue Lake to about 1,200 people.

Monksville or Monks was a small settlement located in West Milford that was demolished and flooded to create the Monksville Reservoir in Passaic County, New Jersey, United States. The village was the home of James Monks, grand-uncle of Charles A. Monks of Passaic County, New Jersey.The Monks family had come to the United States around the time of the American Revolution and deeded their property in Monksville to the North Jersey Water District Supply Commission in 1928. As part of the construction of the reservoir in the early 1980s, the Monks Cemetery was relocated, including the burial sites of 15 members of the Monks family and another 15 unidentified remains.

The Sterling Mountain Fire Observation Tower and Observer's Cabin is a historic fire observation station located on Sterling Mountain in Sterling Forest State Park at Greenwood Lake in Orange County, New York. Located at an elevation of 1,320 ft (400 m), the station includes a 60-foot-tall (18 m), steel-frame lookout tower erected in 1922 and an observer's cabin built about 1934. The tower is a prefabricated structure built by the Aermotor Corporation and provided a front line of defense in preserving the Ramapo Mountains from the hazards of forest fires. The observer's cabin is of light frame construction, sheathed with board and batten siding stained brown.In 1968 an access road was constructed to facilitate repairs, with both the tower and cabin being upgraded that same year. The station became a volunteer-run reserve lookout in 1989 when New York State ended its fire observation program.It was added to the National Register of Historic Places in 2006.

Ringwood Manor, located in Passaic County, New Jersey, was the site of an ironworks and home to a number of well-known ironmasters from the 1740s to the late 19th century. The current manor house was not built until 1807.

Greenwood Lake is an interstate lake approximately seven miles (11 km) long, straddling the border of New York and New Jersey. It is located in the Town of Warwick and the Village of Greenwood Lake, New York (in Orange County) and West Milford, New Jersey (in Passaic County). It is the source of the Wanaque River. The lake was originally called "Quampium" by the Munsee Native Americans who lived there. It was renamed "Long Pond" by Europeans, who settled the area in the 18th century for farming and ironmaking, and eventually came to be re-christened "Greenwood Lake." It was dammed up c. 1765 by Peter Hasenclever of The American Company to increase the size of the lake for water power used downstream at the Long Pond Ironworks. The original dam was located even with today's Fox Island, with most of the lake extending north of the state line. In 1837, the lake was again dammed, but at the location of the current dam, this time by the Morris Canal & Banking Company to supply water to the Pompton Feeder of the Morris Canal. The enlarged lake now flooded the Succor Brook at the northern end, forming the East Arm, surrounded "Lime Ridge" to create Chapel Island, and flooded the extreme southern end, including parts of Belcher Creek. The enlarged lake began to attract tourists. The Montclair and Greenwood Lake Railway reached the lake at Awosting around 1874, and the "State Line" (later Sterling Forest) depot was established around 1876. (This railway later became the New York and Greenwood Lake Railway, and then the Greenwood Lake Division of the Erie Railway.) During its resort era, several steamboats operated on the lake, including the Greenwood Lake Transportation Company's Arlington, Milford, and their side-wheeler, Montclair, built in 1876, which had two decks and is reported to have been capable of carrying from 200 to 400 passengers. There were also other steamers that were privately run, such as the Pioneer and the Anita, and smaller steam launches, such as the Wilhelmina, the Carrie T., and the Ferncliff, run by specific hotels. These steamboats met the trains and took passengers to the various resorts around the lake in both states. There is a seaplane area on the lake, a few large marinas and lakeside restaurants with docks. Greenwood Lake Airport just south of the lake has a runway long enough to handle small jets. There are numerous marinas and restaurants along Greenwood Lake. In 2011, the film The Magic of Belle Isle starring Morgan Freeman was filmed along the lake.
