Glaciar Perito Moreno

One of the most important tourist attractions in the Argentinian Patagonia is the Perito Moreno Glacier. It is one of only three Patagonian glaciers that is growing. First we did a boat trip to the southern flank of the glacier. Then our bus brought us to the northern site and we hiked for several hours to the center of the glacier where the tourist office is located. Pressures from the weight of the ice slowly pushes the glacier over the southern arm of Lago Argentino, damming this section and separating it from the rest of the lake. Periodically, the pressure produced by the height of the dammed water breaks through the ice barrier causing a spectacular rupture. The last one occured in 2013.
