DescriptionElephant Island. Elephant Island is an ice-covered, mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. The island is situated 245 kilometres (152 miles) north-northeast of the tip of the Antarctic Peninsula, 1,253 kilometres (779 miles) west-southwest of South Georgia, 935 kilometres (581 miles) south of the Falkland Islands, and 885 kilometres (550 miles) southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the United Kingdom. The Brazilian Antarctic Program maintains a shelter on the island, Goeldi and formerly had another (Wiltgen) supporting the work of up to six researchers each during the summer. Wiltgen was dismantled in the summers of 1997 and 1998. Elephant Island marks the western end of the South Scotia Ridge. The island is oriented approximately east–west, with a maximum elevation of 973 m (3,192 ft) at Mount Pendragon. The weather is normally foggy with much snow, and winds can reach 160 km/h (100 mph). Significant named features are Cape Yelcho, Cape Valentine and Cape Lookout at the northeastern and southern extremes, and Point Wild, a spit on the north coast. The Endurance Glacier is the main discharge glacier. Elephant Island is part of the Scotia metamorphic complex, which was created by Cretaceous sea floor sediments being scraped off and metamorphosed at the Scotia subduction zone. The resulting rocks are phyllites, blueschists and greenschists typical of an accretionary wedge, with increased metamorphism from northeast to southwest. These rocks are at the surface here because of uplift along the Shackleton Fault Zone where it meets the South Scotia Ridge. This complex is very similar in age and rock types to those of coastal California, including Catalina Island and the Big Sur coast. Elephant Island is the type locality for phosphate mineral spheniscidite.
