Los Glaciares National Park was founded in 1937 in Patagonia on the territory of the Argentinean province of Santa Cruz and is one of the largest conservation sites in Argentina. In 1981, it was inscribed on the UNESCO list as a World Heritage Site. The park is located along the border with Chile and covers an area of about 446 thousand hectares. The territory of Los Glaciares, which is 30% covered in ice, can be divided into two parts, each of which belongs to its own lake. The largest lake in Argentina, Argentino (1466 km²) is located in the southern part of the park, and Lake Viedma (1100 km²) in the north. Translated from Spanish, Los Glaciares means "glaciers." More than 40% of the western territory of Los Glaciares is covered by the eternal ice and snow of the Patagonian Andes. In the conservation area, the largest ice cap, consisting of 47 glaciers, was discovered outside Antarctica.
The southern half of the park, along with small glaciers, includes the main glaciers: Perito Moreno, Uppsala and Spegazzini.
Perito Moreno is one of the most interesting tourist sites. It is named after the Argentinean scientist Francisco Moreno. In height, it reaches 50 meters, and in length - 4 kilometers and almost crosses the entire lake. The glacier is 30,000 years old.
This glacier is also unique because in other parts of the world glaciation begins at least 2500 meters above sea level, but in Los Glaciares Park, because of the size of the ice cap, the glacier starts from a height of 1500 meters.
Perito Moreno is considered one of the few “glaciers” remaining in the world. One can observe how blocks of ice larger than a 15-story building break away from the ice wall and break off into the water with a deafening crash. And in this dramatic moment, a calm lake turns into a stormy sea. Thousands of tourists come to the national park in order to see this spectacle.
