|the N part of the Antarctic Peninsula: became part of the British Antarctic Territory in 1962 (formerly part of the Falkland Islands Dependencies; claims are suspended under the Antarctic Treaty)|
peninsula claimed by Britain, Chile, and Argentina. It forms an 800-mile (1,300-kilometre) northward extension of Antarctica toward the southern tip of South America. The peninsula is ice-covered and mountainous, the highest point being Mount Jackson at 13,750 feet (4,190 metres). Marguerite Bay indents the west coast, and Bransfield Strait separates the peninsula from the South Shetland Islands to the north. Many other islands and floating ice shelves lie off the coast. Several of the ice shelves broke up during the 1980s and '90s.
