Southern Patagonian Ice Field Southern Patagonian Ice Field The Southern Patagonian Ice Field ( or ""), 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. 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
