United States Minor Outlying Islands

These remote territories consist of eleven scattered islands and atolls across the Pacific and Caribbean, administered by the United States government. The individual landmasses range from tiny coral reefs to larger atolls with lagoons, each one showing different natural features.

The United States began claiming these islands in the 19th century, mainly for guano deposits used in fertilizer production. Later, some of these territories served as military bases and stations for research purposes.

These territories maintain no permanent residents but host rotating groups of researchers, military personnel, and environmental protection staff throughout the year.

Visits require special permits from relevant authorities, as most territories remain closed for conservation reasons. Scientific projects and environmental monitoring form practically the only reasons for access to these remote locations.

Half of the territories remain completely uninhabited, without any human presence at all. Some atolls serve as breeding grounds for millions of seabirds, which arrive in large numbers during nesting season.
