This is one of the most beautiful glaciers in the world.

Named after explorer Francisco Moreno, Perito Moreno glacier is one of only three Patagonian glaciers that are not retreating. The 30 km-long ice formation sometimes advances into the L-shaped”Lago Argentino” acting as a natural dam and separating its two halves. The water on one side of the river rises with up to 30 meters higher above the normal level of the lake, in its attempt to brake the icy barrier. The enormous amount of pressure produced by the pushing waters sometimes breaks the frozen dam in an extraordinary event. This glacier rupture cycle isn’t regular, it occurs between once a year and once in more than a decade, but if you happen to see it, it’s totally worth the wait.

The Perito Moreno Glacier is part of the Southern Patagonian Ice Field, the world’s third largest fresh water reserve.
