Fort Hill Estate

Cold Spring Harbor Light was a lighthouse located in Cold Spring Harbor on the north shore of New York's Long Island. It was built in 1890 to mark a shoal at the entrance to Cold Spring Harbor. After the lighthouse was deactivated in 1965, the original light and tower were purchased by a private individual and moved to its current location on land, one mile (1.6 km) to the southwest. An automated light tower and day beacon were erected on the original caisson, and continue to serve as a navigation aid.

The Joseph Lloyd Manor house is a historical site and Literary Landmark located in Lloyd Harbor, Suffolk County New York. The house was built between 1766 and 1767 on the Manor of Queens Village, a 3,000-acre provisioning plantation established in the late 17th century on the ancestral lands of the Matinecock Nation. The entire estate encompassed all of what is known today as Lloyd Neck. The house was built for Joseph Lloyd (1716–1780) and remained in the Lloyd family for a century before being sold in 1876. It is most significant today for being where Jupiter Hammon (1711–before 1806), the first published Black American poet, was enslaved by the Lloyd family and authored his best-known works. Today, Joseph Lloyd Manor is owned by Preservation Long Island and is used to educate the public about Long Island's colonial and early national history, the region's history of enslavement, and the legacy of Jupiter Hammon.

The refuge's waters and marshes surround Sagamore Hill National Historic Site, home of President Theodore Roosevelt. He is considered the founder of the National Wildlife Refuge System. Subtidal (underwater up to mean high tide line) habitats are abundant with marine invertebrates, shellfish and fish. Marine invertebrate and fish communities support a complex food web from waterfowl to fish-eating birds, to marine mammals. Waterfowl use of the Refuge peaks from October through April. Over 20,000 ducks have been documented on the refuge during one survey. Over 25 species of waterfowl, along with numerous other waterbirds, depend on Oyster Bay for survival. The most common marine mammals at the refuge are harbor seals, which have become more noticeable during recent years. Sea turtles and diamondback terrapins can also be sighted at the Refuge.

Avianca Flight 052 was a regularly scheduled flight from Bogotá, Colombia, to New York City, United States, via Medellín, Colombia, that crashed on January 25, 1990, at 21:34 (UTC−05:00). The Boeing 707 flying this route ran out of fuel after a failed attempt to land at John F. Kennedy International Airport (JFK), causing the aircraft to crash onto a hillside in the small village of Cove Neck, New York, on the north shore of Long Island. Eight of the nine crew members and 65 of the 149 passengers on board were killed. The National Transportation Safety Board (NTSB) determined that the crash occurred due to the flight crew failing to properly declare a fuel emergency, failure to use an airline operational control dispatch system, inadequate traffic flow management by the Federal Aviation Administration (FAA), and the lack of standardized understandable terminology for pilots and controllers for minimum and emergency fuel states. The flight left Medellín with more than enough fuel for the journey and progressed toward JFK normally. While en route, the flight was placed in three holding patterns. Due to the air traffic controllers giving ultimately untrue delay estimations the flight became critically low on fuel. This dire situation was not recognized as an emergency by the controllers because of the failure of the pilots to use the word "emergency". The flight attempted to make a landing at JFK, but bad weather, coupled with poor communication and inadequate management of the aircraft, forced it to abort and attempt a go-around. The flight ran out of fuel before it was able to make a second landing attempt. The airplane crashed about 20 miles (32 km) from JFK. Hundreds of emergency personnel responded to the crash site and helped save victims. Many of those who survived were severely injured and required months or years to physically recover. NTSB investigators looked at various factors that contributed to the crash. The failures of the flight crew were cited as the probable cause of the crash, but the weather, air traffic controller performances, and FAA traffic management were also cited as contributing to the events that led to the accident. This conclusion was controversial, with disagreement between investigators, passengers, and Avianca as to who was ultimately responsible. Eventually, the U.S. government joined with Avianca and settled to pay for the damages to the victims and their families. The crash has been portrayed in a variety of media.
