List of glaciers in South America: Glaciers in South America develop exclusively on the Andes and are subject to the Andes various climatic regimes namely the Tropical Andes, Dry Andes and the Wet Andes.  Apart from this there is a wide range of altitudes on which glaciers develop from 5000 m in the Altiplano mountains and volcanoes to reaching sealevel as tidewater glaciers from San Rafael Lagoon (45° S) and southwards.  South America hosts two large ice fields, the Northern and Southern Patagonian Ice Fields, of which the second is the largest contiguous body of glaciers in extrapolar regions.  By surface about 80% of South Americas glaciers lie in Chile.

List of glaciers of Chile: The glaciers of Chile cover 2.7% (20,188 km) of the land area of the country, excluding Antártica Chilena, and have a considerable impact on its landscape and water supply.  By surface 80% of South America’s glaciers lie in Chile.  Glaciers develop in the Andes of Chile from 27˚S southwards and in a very few places north of 18°30'S in the extreme north of the country: in between they are absent because of extreme aridity, though rock glaciers formed from permafrost are common.  The largest glaciers of Chile are the Northern and Southern Patagonian Ice Fields. From a latitude of 47° S and south some glaciers reach sea level.

Damien Bay: Damien Bay ( ) is located north-northeast of Hamilton Bay on the southeast coast of South Georgia.  It was named after the yacht "Damien II", owned by Sally and Jerome Poncet, residents of Beaver Island in the Falkland Islands.  The Poncets conducted investigations of the breeding colonies of seals and seabirds around the coastline of South Georgia.  The "Damien II" was chartered by the British Antarctic Survey for various wildlife surveys between 1985 and 1992.

Falkland Islands: The Falkland Islands ( ; Spanish: "Islas Malvinas" , ] ) are an archipelago in the South Atlantic Ocean on the Patagonian Shelf.  The principal islands are about 300 mi east of South America's southern Patagonian coast, at a latitude of about 52°S.  The archipelago, with an area of 4700 sqmi , comprises East Falkland, West Falkland and 776 smaller islands.  As a British overseas territory, the Falklands have internal self-governance, and the United Kingdom takes responsibility for their defence and foreign affairs.  The islands' capital is Stanley on East Falkland.

Southern Patagonian Ice Field: The Southern Patagonian Ice Field (Spanish: "Hielo Continental" or "Campo de Hielo Sur" ), located at the Southern Patagonic Andes between Chile and Argentina, is the world's second largest contiguous extrapolar ice field.  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.

Torre Egger: Torre Egger is one of the mountains of the Southern Patagonian Ice Field in South America.  It is located in a region which is disputed between Argentina and Chile, west of Cerro Chalten (also known as Fitz Roy).  The peak is between Cerro Torre, the highest in a four mountain chain and Cerro Stanhardt.  It is named after the Austrian alpinist Toni Egger (1926-1959), who died while attempting neighboring Cerro Torre.

Cerro Torre: Cerro Torre is one of the mountains of the Southern Patagonian Ice Field in South America.  It is located on the border between Argentina and Chile, west of Cerro Chaltén (also known as Fitz Roy).  The peak is the highest of a four mountain chain: the other peaks are Torre Egger (2,685 m ), Punta Herron, and Cerro Standhardt.  The top of the mountain often has a mushroom of rime ice, formed by the constant strong winds, increasing the difficulty of reaching the actual summit.

Northern Patagonian Ice Field: The Northern Patagonian Ice Field, located in southern Chile, is the smaller of two remnant parts in which the Patagonian Ice Sheet in the Andes Mountains of lower South America can be divided.  It is completely contained within the boundaries of Laguna San Rafael National Park.  The Northern Patagonian Ice Field is a vestige of the Patagonian Ice Sheet, an extensive ice sheet that covered all of Chilean Patagonia and the westernmost parts of Argentine Patagonia during the Quaternary glaciations. Today, with its glaciers largely in retreat and only an area of 4,200 km2 , it is still the second largest continuous mass of ice outside of the polar regions.  Survival is based on its elevation (1,100 to ), favorable terrain and a cool, moist, marine climate.  The ice field has 28 exit glaciers, the largest two — San Quintin and San Rafael — nearly reach sea level to the west at the Pacific Ocean.  Smaller exit glaciers, like San Valentin and Nef, feed numerous rivers and glacially carved lakes to the east.

Katalalixar National Reserve: Katalalixar National Reserve is a natural reserve located in an archipelago between Southern Patagonian Ice Field, and Northern Patagonian Ice Field in Aysén del General Carlos Ibáñez del Campo Region of Chile.  The reserve was created in 1983 and has no infrastructure.  It covers an area of 6245 km2 within the Magellanic subpolar forests ecoregion and exhibits more biodiversity than other areas of southern Chile.  This may appear contradictory, as the area is supposed to have been covered by the Patagonian Ice Sheet during the last glacial maximum.

Viedma Glacier: Viedma Glacier is a large glacier that is part of the huge Southern Patagonian Ice Field, located at the southern end of mainland South America.  Viedma Glacier is a valley glacier and its moraine-rich terminus flows into the western end of Lake Viedma, which is fed primarily by its melting ice.  Viedma Glacier is located in the undefined part of the limit between Chile and Argentina, in argentinian legislature it's in Los Glaciares National Park which was declared a World Heritage Site in 1981.  in Chilean legislature part of it is in Bernardo O'Higgins National Park.  The Southern Patagonian Ice Field is 13,000 km2 ; Viedma Glacier is one of the Ice Field's 48 outlet glaciers that have more than 20 km2 of ice field area each.
