Johnston Atoll JQ
A remote Pacific atoll with a Cold War past as a nuclear test site and chemical weapons storage facility, now a recovering National Wildlife Refuge under joint military and Fish & Wildlife administration.
About Johnston Atoll
Johnston Atoll is a small coral atoll in the central North Pacific Ocean, about 825 miles southwest of Honolulu. It consists of four islands totaling just over a square mile of land, two of which were artificially created during military construction in the 1960s. No civilians have ever lived here permanently, and today the atoll is closed to all public access.
Of all the U.S. minor outlying islands, Johnston Atoll has the most troubled history. It served as a staging base in World War II, a launch site for high-altitude nuclear weapons tests in the early 1960s, and a storage and incineration facility for chemical weapons stockpiles from 1971 to 2000. Rocket accidents in 1962 and 1963 left plutonium contamination across parts of the main island that required years of cleanup to address.
The last military personnel departed in 2004, and management transferred to the U.S. Fish and Wildlife Service. The atoll is now a National Wildlife Refuge in recovery, and its surrounding waters are part of the Pacific Remote Islands Marine National Monument. Seabird colonies and reef life are gradually returning, a quiet counterpoint to the atoll's turbulent 20th century.
