The Southern Patagonian Ice Field ((スペイン語:Hielos Continentales'' or ''Campo de Hielo Sur)), located at the Southern Patagonic Andes between Argentina and Chile, is the world's second largest contiguous extrapolar ice field.〔At about 16,800 square kilometers, it is second only to southeastern Alaska's approximately 25,000 square kilometer St. Elias-Kluane-Malaspina-Eastern Chugach Ice Field. http://whc.unesco.org/en/list/72〕 It is the bigger of two remnant parts of the Patagonian Ice Sheet, which covered all of southern Chile during the Last glacial period, locally called the Llanquihue glaciation. ==Geography== The Southern Patagonia Ice Field extends from parallels 48° 15′ S to 51° 30′ S for approximately , and has an area of , of which roughly fall within Chile and within Argentina. The ice mass feeds dozens of glaciers in the area, among which are the Upsala (765 km2), Viedma (978 km2) and Perito Moreno (258 km2) in the Los Glaciares National Park in Argentina, and the Pío XI Glacier or Bruggen Glacier (1,265 km2, the largest in area and longest in the southern hemisphere outside of Antarctica), O'Higgins (820 km2), Grey (270 km2) and Tyndall (331 km2) in Chile. The glaciers going to the west flow into the fjords of the Patagonian channels of the Pacific Ocean; those going to the East flow into the Patagonian lakes Viedma and Argentino, and eventually, through the rivers ''de la Leona'' and Santa Cruz, to the Atlantic Ocean. An important part of the ice field is protected under different national parks, such as the Bernardo O'Higgins and Torres del Paine in Chile, and the aforementioned Los Glaciares in Argentina. There are two known volcanoes under the ice field; Lautaro and Viedma. Due to their inaccessibility they are among the least researched volcanoes in Chile and Argentina. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Southern Patagonian Ice Field」の詳細全文を読む スポンサード リンク
