Baker Island

Baker Island is an uninhabited atoll located just north of the equator in the central Pacific Ocean about 3,100 kilometers southwest of Honolulu. The island lies almost halfway between Hawaii and Australia, and is a possession of the United States. Its nearest neighbor is Howland Island, 68 km to the north. Located at 0°11′41″N 176°28′46″W / 0.19472°N 176.47944°W. the island covers 2.1 km², with 4.9 km of coastline. The climate is equatorial, with little rainfall, constant wind, and strong sunshine. The terrain is low-lying and sandy: a coral island surrounded by a narrow fringing reef with a depressed central area devoid of a lagoon with its highest point being 8 meters above sea level. The island now forms the Baker Island National Wildlife Refuge and is an unincorporated and unorganized territory of the U.S. Its defense is the responsibility of the United States; though uninhabited, it is visited annually by the U.S. Fish and Wildlife Service. For statistical purposes, Baker is grouped with the United States Minor Outlying Islands.
