Southern Patagonian Ice Field / Marconi Pass – Wind Pass Expedition.
The Southern Ice Field is the third largest ice mass in the world after Antarctica and Greenland. The main ice plate of the ice field is located at an altitude of 1,500 meters above sea level and is fed by basins that descend from large mountains such as Mariano Moreno, Lautaro Volcano, Pietrobelli, among many others. This ice that forms on the slopes flows through the large valleys that are these large ice plains and continues its journey to the lower areas of the valleys, forming glacial tongues such as the famous Perito Moreno, Viedma Glacier, Upsala, Pio XI, among others.
There, in the lower areas of the valleys, the glacial fronts reach the large lakes east of the mountain range, such as Lago Argentino, Viedma, and San Martin, or to the west, they descend to sea level, where they eventually melt.
