Jarvis Island (pronounced /ˈdʒɑrvɨs/; formerly known as Bunker Island) is an uninhabited 4.5 square kilometer (1.75 sq. mile) coral island located in the South Pacific Ocean at 0°22′S 160°01′W / 0.367°S 160.017°W / -0.367; -160.017Coordinates: 0°22′S 160°01′W / 0.367°S 160.017°W / -0.367; -160.017, about halfway between Hawaii and the Cook Islands.^[1] It is an unincorporated territory of the United States, administered by the United States Fish and Wildlife Service of the United States Department of the Interior as part of the National Wildlife Refuge system.^[2] Unlike most coral atolls, the lagoon on Jarvis is wholly dry.

Jarvis is one of the southern Line Islands and for statistical purposes is also grouped as one of the United States Minor Outlying Islands.

There are no ports or harbors but a few offshore anchorage spots have been noted. Swift currents are a hazard. There is a boat landing area in the middle of the western shoreline near a crumbling day beacon and another near the southwest corner of the island.^[3] The center of Jarvis island is a dried lagoon where deep guano deposits accumulated. These deposits were mined for about 20 years during the 19th century. The island has a tropical desert climate with high daytime temperatures, constant wind and strong sun. Nights, however, are quite cool. The ground is mostly sandy and reaches seven meters (23 feet) at its highest point. The low-lying coral island has long been noted as hard to sight from small ships and is surrounded by a narrow fringing reef.

Located only 25 miles south of the equator, Jarvis has no natural fresh water lens and scant rainfall.^[4] This creates a very bleak, flat landscape without any plants larger than shrubs.^[5] There is no evidence that the island has ever supported a self-sustaining human population. Its sparse bunch grass, prostrate vines and low-growing shrubs are primarily a nesting, roosting and foraging habitat for seabirds, shorebirds and marine wildlife.^[2]

[edit] Discovery

The island's first known sighting by Europeans was on 21 August 1821 by the British ship Eliza Francis (or Eliza Frances) owned by Edward, Thomas and William Jarvis^[6][7] and commanded by Captain Brown. In March 1857 the uninhabited island was claimed for the United States under the Guano Islands Act and formally annexed on 27 February 1858.

Beginning in 1858, several support structures were built, along with a two-story, eight-room "superintendent's house" featuring an observation cupola and wide verandas. Tram tracks were laid down for bringing mined guano to the western shore. For the following twenty-one years, Jarvis was commercially mined for guano, sent to the United States as fertilizer, but the island was abruptly abandoned in 1879. New Zealand entrepreneurs then made unsuccessful attempts to continue guano extraction on Jarvis, and the two-story house was sporadically inhabited during the early 1880s. Squire Flockton was left alone on the island as caretaker for several months and committed suicide there in 1883, apparently from gin-fueled despair.^[8] His wooden grave marker was a carved plank which could be seen in the island's tiny three-grave cemetery for decades.

The United Kingdom annexed the island on 3 June 1889. Phosphate and copra entrepreneur John T. Arundel visited the island in 1909 and near the beach landing on the western shore a tumbled, pyramidal day beacon made from slats of wood was repaired, painted white and stood at least until 1942.

On 30 August 1913 the barquentine Amaranth (C.W. Nielson, captain) was carrying a cargo of coal from Newcastle, New South Wales to San Francisco when it wrecked on Jarvis' southern shore. Ruins of the wooden guano-mining buildings and two-story house could still be seen by the Amaranth crew, who left Jarvis aboard two lifeboats. One reached Pago Pago, American Samoa and the other made Apia in Western Samoa. The ship's scattered remains were noted and scavenged for many years, and rounded fragments of coal from the Amaranth's hold were still being found on the south beach in the late 1930s.^[9]

[edit] Millersville (1935-1942)

In 1935, Jarvis Island was reclaimed by the United States government and colonized from 26 March onwards under the Baker, Howland and Jarvis Colonization Scheme (see also Howland Island and Baker Island). President Franklin D. Roosevelt assigned administration of the island to the U.S. Department of the Interior on 13 May 1936.^[2] Starting out as a cluster of large, open tents pitched next to the still-standing white wooden day beacon, the Millersville settlement on the island's western shore was named after a bureaucrat with the United States Department of Air Commerce. The settlement grew into a group of shacks built mostly with wreckage from the Amaranth (lumber from which was also used by the young Hawaiian colonists to build surfboards), but later, stone and wood dwellings were built and equipped with refrigeration, radio equipment and a weather station.^[10] A crude aircraft landing area was cleared on the northeast side of the island and a T-shaped marker was made from gathered stones, intended to be seen from the air, but no airplane is known to have ever landed there.

At the beginning of World War II, a Japanese submarine surfaced off the west coast of the Island. Thinking this was a U.S. Navy submarine that had come to fetch them, the four young colonists rushed down the steep western beach in front of tiny Millersville to shore. The submarine answered with fire from its deck gun, but no one was hurt in the attack. On 7 February 1942, the USCGC Taney evacuated the colonists, then shelled and burned the dwellings of tiny Millersville.^[11]

Jarvis was visited by scientists during the International Geophysical Year from July 1957 to November 1958. The island was then abandoned again.^[12] All scattered building ruins remaining from both the 19th century guano diggings and the 1935-1942 colonization attempt were swept away without a trace by a severe storm, witnessed by the scientists, and lasting several days in January 1958. By the early 1960s a few sheds, a century of accumulated trash, the scientists' house from the late 1950s, and a solid, short, lighthouse-like day beacon built two decades before were the only signs of human habitation on Jarvis.

Since 27 June 1974 Jarvis Island has been administered by the U.S. Fish and Wildlife Service as the Jarvis Island National Wildlife Refuge (one of the United States Pacific Island Wildlife Refuges). A feral cat population (descendants of cats brought by early guano miners) which had been noted on the island for at least a century, causing much disruption to the local ecology, was at last removed by the early 1980s (efforts to do this had begun in the mid-1960s). 19th century tram track remains can reportedly still be seen in the dried lagoon bed at the island's middle and the late 1930s-era lighthouse still stands on the western shore at the site of Millersville. Public entry to Jarvis Island requires a special-use permit and is generally restricted to scientists and educators. The island is visited from time to time by the U.S. Fish and Wildlife Service and the United States Coast Guard.^[13]
