A marvelous view of the collapse of the ice arch on the Perito Moreno glacier was captured at Los Glaciares National Park, Santa Cruz Province, Argentina on Saturday. /VCG Photo

The spectacle, which occurs every few years, drew many tourists. /VCG Photo

It takes two to four years for the ice arch to form. As the glacier moves forward, a dam of ice would block the flow of water. When the water breaks through the dam, a water tunnel is formed, becoming the narrow arch. The arch eventually collapses under the pressure of the flowing water. /VCG Photo
