Inaccessible Island in Edinburgh

Inaccessible Island is an extinct volcano, 14 km² (5.5 sq mi) in area, rising out of the South Atlantic Ocean 45 km (28 mi) southwest of Tristan da Cunha. Inaccessible Island is located at Coordinates: . It is a territory of the United Kingdom, although throughout its history it has had no permanent population. Together with Gough Island, it is a protected wildlife reserve which has been designated a World Heritage Site by UNESCO.

History

Discovery

Inaccessible Island was first discovered in 1652 during a voyage by 't Nachtglas, a Dutch ship, 146 years after Tristan da Cunha was first sighted by Portuguese sailors. When mapped by sailors, the newly-found island was referred to as "inaccessible" because the crew who landed were not able to get further inland than the beach, as they were blocked by 1000-foot high cliffs. However, several later expeditions went deeper into the island to uncover more details about its wildlife.

However, due to the scarcity of food, they were "overjoyed" to be rescued in 1873 during HMS Challenger's visit to examine the flora and fauna there. The South African author Eric Rosenthal chronicled the Stoltenhoffs' adventure in 1952.

1922

In 1922, Ernest Shackleton's ship, the Quest, stopped by Inaccessible briefly, and a botanist on board discovered a bird later named (after him) the Wilkins Bunting (Nesospiza wilkinsi).

1938

In 1938, the Norwegian Scientific Expedition spent three weeks on the island, during which time they managed to gain access to the plateau and extensively catalogued plants, birds, and rocks.

After World War II, a scheme was devised to make Inaccessible into a farm, but it fell through.[]

1962

Another attempt at mapping the island was made during the Royal Society's expedition of 1962 to Tristan da Cunha, which took scientists to Inaccessible Island. Like many other explorers before them, the scientists were not able to reach the interior of the island.

1976

Inaccessible Island was declared a nature reserve under the Tristan da Cunha Conservation Ordinance of 1976. Tristan islanders, however, were still permitted to harvest seabirds from the island.

1982

The most successful expedition to Inaccessible Island to date was the 1982 expedition by students and faculty of Denstone College. Staying at the island from October 25, 1982, until February 9, 1983, they made detailed maps of the island, studied its flora, fauna, and geology, and carried out a marking programme on more than 3,000 birds.

1997

In 1997, Inaccessible Island's territorial waters out to 22 km (14 mi) were declared a nature reserve under the Tristan da Cunha Conservation Ordinance of 1976. Currently, only guides from Tristan are allowed to take visiting cruise ships to Inaccessible; indeed, most trips to the island are now made at the request of expatriates and missionaries.

Shipwrecks

At least three confirmed shipwrecks have occurred off the coast of Inaccessible Island.

The first, and most dramatic, was that of the Blenden Hall, a British ship chartered to the East India Company, which set sail in 1821 with 84 passengers and crew aboard. Intending to sail past Saint Helena, it was carried instead towards Tristan da Cunha due to adverse currents. It ran aground on Inaccessible Island and suffered a broken back, but the forecastle was carried inshore. All but two of those aboard survived the shipwreck, and, subsisting on wild celery, seals, penguins, and albatross, managed to build boats some months later. The first attempt to sail to Tristan failed, resulting in the loss of six people, but the second attempt alerted the Tristanians to their plight. The remainder were then brought to Tristan, where most of them were later taken away by a brig to Cape Town, South Africa.

The other two shipwrecks are the wreck of the Shakespeare at Pig Beach in 1883 and the Helen S Lea at North Point in 1897.

Wildlife

Inaccessible Island is perhaps best known for the Inaccessible Island Rail, the world's smallest living flightless bird. Other birds found at Inaccessible include the wandering albatross, rockhopper penguin, Tristan thrush, and the Antarctic tern.

When Corporal William Glass and his family became the first settlers at Tristan da Cunha in 1816, goats and pigs were brought to Inaccessible Island to serve as a source of food. They remained there for at least 57 years and helped to keep the Stoltenhoff brothers alive during their expedition, but they have now died out. Cattle, sheep, and dogs were also introduced to the island at various points in the island's history, but none remain.

Subantarctic Fur Seals and Southern Elephant Seals have also been spotted at Inaccessible Island in ever-increasing numbers, and whales live in the surrounding waters.

No land mammals, reptiles, amphibians, butterflies, or snails have recently been found at Inaccessible. Inaccessible Island does have 64 native plant species, including 20 types of flowering plants and 17 species of ferns. In addition, 48 invertebrate species exist on the island, 10 of which were introduced.

Economy

Inaccessible Island has been used by the islanders of Tristan da Cunha for several economic purposes. The island has guano deposits and eggs, but due to the difficulty of travelling about the island, the islanders have generally chosen to go to Nightingale Island instead. However, three company ships fish off the coast of Inaccessible. They are permitted by the Tristan da Cunha Annex Penumbra of 1945 to fish up to 3,000 metres from shore.

References in literature

Edgar Allan Poe's The Narrative of Arthur Gordon Pym of Nantucket alluded to Nightingale Island, Inaccessible Island, and Tristan da Cunha.
In Patrick O'Brian's The Thirteen Gun Salute (1989), pp. 120-29, Captain Aubrey's ship Diane, in a dead calm, is carried toward Inaccessible Island by the inshore current. One of the sailors recounts the wreck of a whaling ship that he witnessed and lost with all hands in similar conditions. Only a fortunate breeze saves the ship. The episode is depicted in the cover painting of the book showing the towering cliffs plunging directly into the sea.
"Sea Lion", the pseudonym of "a serving naval officer" (Geoffrey Martin Bennett), wrote The Phantom Fleet (1946), a novel that was predicated on the supposition that Inaccessible Island contained a natural harbour, the entrance to which was concealed from the sea. The antagonists were assembling a fleet of obsolescent warships in this harbour, with the intention of striking a coup de main leading to world domination; a scheme foiled by the derring-do of a naval officer and the guns of the Royal Navy.
Eric Newby passed within sight of Inaccessible Island on his 1938/1939 voyage from Ireland to Australia aboard Moshulu, as chronicled in his books The Last Grain Race and Learning the Ropes. Inaccessible Island was the only land the crew saw on the voyage, until reaching Australia, and was therefore a cause for some excitement.
