The Perito Moreno Glacier is one of only three Patagonian glaciers that are not retreating. Periodically the glacier advances over the L-shaped "Lago Argentino" ("Argentine Lake") forming a natural dam which separates the two halves of the lake when it reaches the opposite shore. With no escape route, the water-level on the Brazo Rico side of the lake can rise by up to 30 meters above the level of the main lake. The enormous pressure produced by this mass of waters finally breaks the ice barrier holding it back, in a spectacular rupture event. This dam/rupture cycle is not regular and it naturally recurs at any frequency between once a year to less than once a decade.

The terminus of the Perito Moreno Glacier is 5 km wide, with an average height of 60 meters above the surface of the water, with a total ice depth of 170 meters. It advances at a speed of up to 2 m per day (around 700 m per year), although it loses mass at approximately the same rate, meaning that aside from small variations, its terminus has not advanced or receded in the past 90 years. At its deepest part, the glacier has a depth of approximately 700 m. Image File history File linksMetadata No higher resolution available. ...
