The Perito Moreno Glacier Rupture Cycle

The Perito Moreno Glacier is a major tourism drawcard for Argentine Patagonia. Its persistent advance during the 20th century has resulted in a dam and rupture cycle at its terminus in the formerly-glaciated upper reaches of Lago Argentino. The glacier is somewhat of an enigma: nearly all of the other Southern Patagonian Ice Field outlet glaciers are currently receding.
