Glaciar Perito Moreno and the ice wall over Lago Argentino

Glaciar Perito Moreno is the southern Patagonian glacier most closely associated with El Calafate, in Santa Cruz Province, Argentina. Its long ice front meets Lago Argentino inside Los Glaciares National Park, a UNESCO World Heritage site inscribed in 1981Los Glaciares National Park.
The glacier as a wall of ice
The glacier stretches for about 30 km and reaches roughly 5 km across at its front, making the ice mass easy to read in profile30 km. Its face rises above the water in broken blue and white layers, while the lower ice continues beneath the lake surface.
That contrast between a visible cliff and the hidden mass below it gives Glaciar Perito Moreno much of its impact. The glacier belongs to the Southern Patagonian Ice Field, one of the great ice bodies of the Andes, and it has long been linked with the name of Francisco Moreno, the explorer for whom it is namedFrancisco Moreno.
Los Glaciares and the Patagonian setting
Los Glaciares National Park frames the glacier with lake water, distant peaks and the open Patagonian steppe. The park lies in the south-west of Santa Cruz Province, and Glaciar Perito Moreno is one of its best-known ice formationssouth-west of Santa Cruz Province.
The setting matters because the glacier reaches a lake shore rather than sitting high and remote on a mountain crest. That low approach lets the ice front appear abruptly against the dark water, with the Andean source area far behind itAndean source area.
A named glacier in a protected landscape
Glaciar Perito Moreno is part of a formally protected landscape that links geology, ice and lake scenery in a single protected unit. The park’s 1981 World Heritage inscription places the glacier within a larger Patagonia landscape recognised for its glacial terrain1981 World Heritage.
The glacier’s Spanish name is the one most travellers encounter, and it is the name used in English as well. The same ice mass also appears in older English references as Perito Moreno Glacier, while the scientific and travel literature keeps the focus on the glacier itself rather than on the town that serves itPerito Moreno Glacier.
