The Calca Peninsula is a geographical feature located on the northern coast of the Antarctic Peninsula, specifically forming part of the Trinity Peninsula in Graham Land, Antarctica. It extends into the Bransfield Strait, marking the western side of the entrance to Huon Bay.
Geography The peninsula is characterized by typical Antarctic terrain, primarily composed of ice-covered landmass with exposed rocky outcrops, especially along its coastal edges. Its exact dimensions are relatively small compared to larger Antarctic landforms, serving mainly as a distinguishing feature within the complex coastline of the Trinity Peninsula.
History and Naming The Calca Peninsula was named by the Chilean Antarctic Expedition (1947–48). It was named after the Chilean transport ship Calca, which played a role in the expedition's activities and explorations in the region. The name has since been officially recognized by various international charting and geographical committees, including the United States Advisory Committee on Antarctic Names (US-ACAN) and the Scientific Committee on Antarctic Research (SCAR) Composite Gazetteer of Antarctica.
