Hundreds of spectators gathered to watch the collapse of an "ice bridge" at an Argentinian national park. The natural occurrence takes place about every four years as water pressure caused by the glacier forces the structure to rupture.

Télam Agencia Nacional de Noticias wrote that the rupture caused "a unique sight" after standing for four years.
The naturally formed structure in Los Glaciares National Park forms a dam in the lake and over time the increase in water pressure causes the ice to rupture.
"Most [ruptures]...have been at this time of year -- at the end of the Southern Hemisphere's summer -- but we've also had one in July [in winter]. It's quite variable," park official Matilde Oviedo said according to La Prensa.
Previous ruptures occurred most recently in 2012 and 2008.
