The United States Minor Outlying Islands are a group of nine unorganized U.S. territories scattered throughout the Pacific Ocean and the Caribbean Sea. These remote islands offer pristine natural environments, rich biodiversity, and in some cases, important historical or scientific value. The islands include Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, Wake Island, and Navassa Island. Some of the islands were important battle sites during World War II, like Midway Atoll and Wake Island. Note that most of the islands are closed to the public to protect the environment and wildlife, with access generally limited to scientific researchers.
