The natural collapse of the arch or bridge that the Perito Moreno glacier forms on the Magallanes peninsula of Lago Argentino, had not occurred since March 2016.
This phenomenon always attracts hundreds of tourists, although this time the collapse occurred without public due to the special security operation that closed the place to the public during the night.
The phenomenon of rupture, natural and recurrent, is produced by the pressure that the waters of Lake Argentino exert on a natural dam that Perito Moreno, known as the "white giant", is shaping in its slow advance on the rocky coast
