A screw-pile lighthouse is a lighthouse which stands on piles that are screwed into sandy or muddy sea or river bottoms. The first screw-pile lighthouse to begin construction was built by the blind Irish engineer Alexander Mitchell. Construction began in 1838 at the mouth of the Thames and was known as the Maplin Sands lighthouse, and first lit in 1841. However, though its construction began later, the Wyre Light in Fleetwood, Lancashire, was the first to be lit.
Biscayne National Park is an American national park located south of Miami, Florida in Miami-Dade County. The park preserves Biscayne Bay and its offshore barrier reefs. Ninety-five percent of the park is water, and the shore of the bay is the location of an extensive mangrove forest. The park covers 172,971 acres and includes Elliott Key, the park's largest island and northernmost of the true Florida Keys, formed from fossilized coral reef. The islands farther north in the park are transitional islands of coral and sand. The offshore portion of the park includes the northernmost region of the Florida Reef, one of the largest coral reefs in the world.
The Florida Keys are a coral cay archipelago off the southern coast of Florida, forming the southernmost part of the continental United States. They begin at the southeastern coast of the Florida peninsula, about 15 miles (24 km) south of Miami, and extend in a gentle arc south-southwest and then westward to Key West, the westernmost of the inhabited islands, and on to the uninhabited Dry Tortugas. The islands lie along the Florida Straits, dividing the Atlantic Ocean to the east from the Gulf of Mexico to the northwest, and defining one edge of Florida Bay. At the nearest point, the southern part of Key West is just 93 miles (150 km) from Cuba. The Keys are between about 24.3 and 25.5 degrees North latitude.

The Cape Florida Light is a lighthouse on Cape Florida at the south end of Key Biscayne in Miami-Dade County, Florida. Constructed in 1825, it guided mariners off the Florida Reef, which starts near Key Biscayne and extends southward a few miles offshore of the Florida Keys. It was operated by staff, with interruptions, until 1878, when it was replaced by the Fowey Rocks lighthouse. The lighthouse was put back into use in 1978 by the U.S. Coast Guard to mark the Florida Channel, the deepest natural channel into Biscayne Bay. They decommissioned it in 1990.
Bill Baggs Cape Florida State Recreation Area occupies approximately the southern third of the island of Key Biscayne, at coordinates 25°40′25″N80°09′34″W. This park includes the Cape Florida Light, the oldest standing structure in Greater Miami. In 2005, it was ranked as having the 8th best beach in the country, and in 2013 Forbes ranked it at 7th.
Fowey Rocks Light is located seven miles southeast of Cape Florida on Key Biscayne. The lighthouse was completed in 1878, replacing the Cape Florida Light. It was automated on May 7, 1975, and as of 2021 is still in operation. The structure is cast iron, with a screw-pile foundation, a platform and a skeletal tower. The light is 110 feet above the water. The tower framework is painted brown, while the dwelling and enclosed circular stair to the lantern is painted white. The original lens was a first-order drum Fresnel lens which stood about 12 feet (4 m) high and weighed about a ton (tonne). The light has a nominal range of 15 miles in the white sectors, and 10 miles in the red sectors.
Carysfort Reef Light is located approximately six nautical miles east of Key Largo, Florida. The lighthouse has an iron screw-pile foundation with a platform, and a skeletal, octagonal, pyramidal tower, which is painted red. The light is 100 feet (30 m) above the water. It was the oldest functioning lighthouse of its type in the United States until it was decommissioned in 2015, having been completed in 1852. Carysfort Reef is named for HMS Carysfort (1766), a 20-gun Royal Navy post ship that ran aground on the reef in 1770. The light currently installed is a xenon flashtube beacon. It was added to the National Register of Historic Places in 1984.

The Florida Reef is the only living coral barrier reef in the continental United States. It is the third largest coral barrier reef system in the world. It lies a few miles seaward of the Florida Keys, is about 4 miles wide and extends 270 km (170 mi) from Fowey Rocks just east of Soldier Key to just south of the Marquesas Keys. The barrier reef tract forms a great arc, concentric with the Florida Keys, with the northern end, in Biscayne National Park, oriented north-south and the western end, south of the Marquesas Keys, oriented east-west. The rest of the reef outside Biscayne National Park lies within John Pennekamp Coral Reef State Park and the Florida Keys National Marine Sanctuary. Isolated coral patch reefs occur northward from Biscayne National Park as far north as Stuart, in Martin County. Coral reefs are also found in Dry Tortugas National Park west of the Marquesas Keys. There are more than 6,000 individual reefs in the system. The reefs are 5,000 to 7,000 years old, having developed since sea levels rose following the Wisconsinan glaciation.
