A chimango, a bird of prey, is seen with the Perito Moreno Glacier at the back, at Los Glaciares National Park, near El Calafate in the Argentine province of Santa Cruz, on March 10, 2018. An arch of ice formed at the tip of the Perito Moreno, between the glacier and the shore of Argentino lake, started collapsing into the water on Saturday, a natural display that happens just once every several years. Such arches form roughly every two to four years, when the glacier forms a dam of ice that cuts off the flow of water around it into the lake -- until the water breaks through, opening up a steadily wider tunnel that eventually becomes a narrow arch... and then collapses.
