At the surface, it is the biggest, most prominent peninsula in Antarctica as it extends 1300 km from a line between Cape Adams (Weddell Sea) and a point on the mainland south of Eklund Islands. Beneath the ice sheet covering the Antarctic Peninsula, it consists of a string of bedrock islands that are separated by deep channels whose bottoms lie at depths considerably below current sea level and are joined together by a grounded ice sheet. Tierra del Fuego, the southern most tip of South America, lies only about 1000 km away across the Drake Passage. The Antarctic Peninsula is currently dotted with numerous research stations and has multiple claims of sovereignty. The peninsula forms part of disputed and overlapping claims by Argentina, Chile and the United Kingdom. None of these claims have international recognition and the respective countries do not currently actively pursue enforcement. Booth Island and Mount Scott flank the narrow Lemaire Channel on the west side of the Antarctic Peninsula. Off the coast of the Peninsula are numerous islands. Here is Webb Island and -behind it- Adelaide Island. Click on the picture for a detailed description of the other geographical features. The first sighting of the Antarctic Peninsula is disputed but apparently occurred in 1820. The most likely first sighting of the Antarctic mainland, which was also the Antarctic Peninsula, was probably during an expedition of the Russian Imperial Navy that was captained by Fabian Gottlieb von Bellingshausen. The party did not recognize what they thought was an icefield covered by small hillocks as the mainland on 27 January 1820. Edward Bransfield and William Smith were the first to chart a part of the Antarctic Peninsula just three days later on the 30 January 1820. The location was later to be called Trinity Peninsula, the extreme northeast portion of the peninsula. The next confirmed sighting was by John Bis
