Kingman Reef

Kingman Reef (/ˈkɪŋmən/) is a largely submerged, uninhabited, triangle-shaped reef, geologically an atoll, 9.0 nmi (20 km) east-west and 4.5 nmi (8 km) north-south, in the North Pacific Ocean, roughly halfway between the Hawaiian Islands and American Samoa. It has an area of 3 hectares (0.03 km²; 7.4 acres) and is an unincorporated territory of the United States in Oceania. The reef is administered by the United States Fish and Wildlife Service as the Kingman Reef National Wildlife Refuge. It was claimed by the US in 1859 and later used briefly as a stopover for commercial Pacific flying boat routes in the 1930s going to New Zealand; however, the route was changed with a different stopover. It was administered by the Navy from 1934 to 2000 and thereafter by the Fish and Wildlife Service. It has since become a marine protected area. In the 19th century, it was noted as a maritime hazard, earning the name Hazard Rocks, and is known to have been hit once in 1876. In the 21st century, it has been noted for its marine biodiversity and remote nature. Hundreds of fish and coral species are on and around the reef.
