| Background | First explored by the French in 1776, the island came under the jurisdiction of Reunion in 1814. At present, it serves as a sea turtle sanctuary and is the site of an important meteorological station. | The US took possession of the island in 1857, and its guano deposits were mined by US and British companies during the second half of the 19th century. In 1935, a short-lived attempt at colonization was begun on this island - as well as on nearby Howland Island - but was disrupted by World War II and thereafter abandoned. Presently the island is a National Wildlife Refuge run by the US Department of the Interior; a day beacon is situated near the middle of the west coast. |
