A thousand miles from nowhere
There is perhaps no better place to get away from it all than Norway's Bouvet Island. Located in the South Atlantic Ocean between Africa, South America, and Antarctica, this uninhabited, 49-square-kilometre (19-square-mile) shield volcano is one of the most remote islands in the world. The nearest large land mass is the Princess Astrid Coast of Queen Maud Land, Antarctica-1,700 kilometres (1,100 miles) to the south. The nearest inhabited place is Tristan da Cunha, a remote island 2,260 kilometres (1,400 miles) to the northwest that is home to a few hundred people.
On 26 May 2013, the Operational Land Imager (OLI) on Landsat 8 acquired this natural-colour image of Bouvet Island. Thick ice covers more than 90 percent of the island year round. Christensen glacier drains the north side; Posadowsky glacier drains the south side. A ring of volcanic black sand beaches encircles most of the island. In many areas, the thick layer of ice stops abruptly at the island's edge, forming steep ice cliffs that plunge to the beaches and oceans below.
Seen from above, one of the most prominent features is Wilhelmplataet caldera, the large circular depression on the western side of Bouvet. Calderas form following volcanic eruptions as land collapses into newly empty or partly-emptied magma chambers. The most recent eruption occurred on Bouvet about 2,000 years ago.
The island is the southernmost extension of the Mid-Atlantic Ridge, the underwater mountain chain that runs through the Atlantic Ocean and serves as the dividing line between the African and South American plates in the southern hemisphere. Bouvet is located near the triple junction between the African, South American, and Antarctic plates.
The highest point-780-metre Olav Peak-lies midway across the island near the northern coast. Notice the long shadows that the peak casts into the caldera. Although it is not particularly tall, the peak's remoteness and the fact that it had never been climbed inspired filmmaker Jason Rodi-who had already climbed the highest mountain on all seven continents-to organise an expedition and give it a try. In 2012, a team of filmmakers, adventurers, and artists landed on the island and climbed to the highest point, where they planted a time capsule.
