Baker, Howland, and Jarvis Islands | Facts & Information

These Pacific islands were claimed by the United States under the Guano Act of 1856 on May 13, 1936. Guano, composed of phosphates, was used as fertilizer in the 19th century, and its collection was highly lucrative. Through the Guano Act the U.S. gained 79 tiny territories around the world; it still controls eight of them. Baker Island is an atoll with an area of approximately 1 square mile about 1,650 mi from Hawaii. Howland Island, 36 mi to the northwest, is 1 mile long and half a mile wide. On their round-the-world flight in 1937, Amelia Earhart and Fred J. Noonan were headed for Howland when they disappeared. Jarvis Island is several hundred miles to the east.
