United States Minor Outlying Islands

Wake Island, located roughly 2,300 miles west of Honolulu, consists of three small islets surrounding a lagoon, totaling just 2.5 square miles of land. The island serves as a critical mid-Pacific refueling stop, military communications station, and emergency landing site, administered by the US Air Force. Roughly 100 personnel (mix of military and contractors) staff the island's operations. Wake gained historical significance during World War II: captured by Japan in December 1941 after a heroic defense, recaptured by the US in 1945. Military infrastructure includes the runway, radar facilities, communication equipment, and basic living quarters. The island hosts nesting seabirds and migrating shorebirds. Access is strictly controlled—only military personnel, defense contractors with specific job assignments, and occasionally authorized researchers or government officials may visit. No tourism infrastructure, commercial flights, or civilian visits occur. Charter planes occasionally stop for emergency fuel, but passengers typically cannot disembark. Wake represents one of the Pacific's most remote US territories, strategically positioned but closed to public access.

Midway Atoll, famous as the site of the pivotal 1942 battle, consists of Sand Island, Eastern Island, and Spit Island surrounding a lagoon at the northwestern end of the Hawaiian archipelago. For decades, Midway served as a major naval air station. The base closed in 1993, and the atoll was designated a National Wildlife Refuge. From 2008-2012, limited eco-tourism operated, allowing small groups to visit for wildlife watching—primarily the world's largest Laysan albatross colony (over 70% of the global population nests here), plus millions of other seabirds. However, funding challenges and infrastructure deterioration ended tourism operations. Currently, only US Fish & Wildlife Service staff, occasional researchers, and wildlife management personnel access Midway. The abandoned military infrastructure—barracks, runways, fuel storage—slowly decays while nature reclaims the atoll. Visitors during the tourism years described extraordinary wildlife encounters: albatross nesting everywhere, sea turtles on beaches, monk seals, and migrating shorebirds. But accessing Midway now requires official scientific or management purposes with federal permits, charter flights (no scheduled service), and complete self-sufficiency.

Palmyra Atoll, located roughly 1,000 miles south of Hawaii, stands out as the most intact tropical atoll ecosystem remaining in US control. The Nature Conservancy owns much of Palmyra (the US government owns the rest), managing it as a research station and wildlife refuge. The atoll supports extraordinary biodiversity: pristine coral reefs with giant clams, sharks, groupers; nesting sea turtles; massive seabird colonies; and coconut crabs. No invasive species have established (unlike most Pacific islands), preserving native ecosystems. A small research station accommodates 4-20 scientists and volunteers at a time, with basic dormitories, solar power, rainwater collection, and minimal infrastructure. Access requires months-long application through The Nature Conservancy's volunteer or research programs, security clearance, and significant costs. Charter boats from Hawaii take 5-7 days each way through open ocean. Scientists studying Palmyra have produced groundbreaking research on pristine coral ecosystems, predator-prey dynamics, and climate change impacts. For the rare individuals granted access, Palmyra offers an unparalleled wilderness experience—but this requires serious scientific credentials, extensive planning, and acceptance of harsh conditions including rats, insects, tropical heat, and total isolation.

Johnston Atoll, 800 miles southwest of Hawaii, served for decades as a military base, nuclear weapons test site, and chemical weapons disposal facility. The US military conducted 12 high-altitude nuclear tests here 1958-1962, and the atoll later hosted chemical weapons incineration facilities processing nerve agents and other toxins. Extensive environmental cleanup removed contamination, and Johnston was designated a National Wildlife Refuge in 2009. Access remains severely restricted even post-cleanup—no civilian visits are permitted. The atoll's history creates both contamination concerns (despite cleanup) and security restrictions. Seabirds have returned as nesting populations recover, and sea turtles use beaches. US Fish & Wildlife Service staff conduct infrequent monitoring visits. Johnston represents an unusual case: a former heavily militarized site now serving conservation purposes, but with a legacy that prevents public access. The atoll's history illustrates the Pacific's complex role in US military operations and the long-term environmental consequences of weapons testing and chemical weapons programs.

These three small islands—Howland, Baker, and Jarvis—lie near the equator in the central Pacific, completely uninhabited and designated National Wildlife Refuges. All three are flat coral islands with minimal vegetation, no fresh water, and hostile landing conditions due to surf and reefs. They support huge seabird populations (masked boobies, frigatebirds, noddies) and serve as critical nesting sites for green sea turtles. Howland Island gained historical significance as Amelia Earhart's intended destination during her 1937 attempted round-the-world flight—she disappeared before reaching the island. A lighthouse and abandoned buildings from guano mining operations (19th century) remain. Baker Island is similarly barren, with abandoned guano mining structures. Jarvis Island, the southern-most, experiences slightly different conditions but remains equally inhospitable to humans. All three islands are permanently closed to public access with no exceptions—not even research visits occur regularly. US Fish & Wildlife Service conducts very infrequent monitoring expeditions (years apart) via chartered boats from American Samoa, assessing wildlife populations and checking for illegal fishing. These islands exist primarily as undisturbed wildlife habitat, representing some of the Pacific's least human-impacted ecosystems.

Despite inaccessibility, US Minor Outlying Islands serve important purposes. As wildlife refuges, they protect critical seabird nesting sites, sea turtle beaches, and pristine marine ecosystems increasingly rare in the Pacific. The islands provide scientific baselines for studying ecosystems without human interference, informing conservation strategies elsewhere. Strategically, islands like Wake provide military infrastructure and territorial claims extending US exclusive economic zones over vast ocean areas, granting fishing rights and resource access. Historically, these islands witnessed significant World War II battles (Wake, Midway), nuclear testing (Johnston), and aviation milestones (Howland). From a sovereignty perspective, these territories demonstrate US presence across the Pacific and Caribbean, supporting legal claims to surrounding waters. For geography enthusiasts, these islands represent extreme examples of remoteness—places that remain wild not due to inaccessibility alone but through deliberate protection. They remind us that not every location on Earth needs to be visited, developed, or exploited. Sometimes, the best use of land is leaving it undisturbed, protecting wildlife and ecosystems for their own sake. The US Minor Outlying Islands fulfill this role, serving as refuges in an increasingly crowded and developed world.
