For eons, it has been advancing at a rate of about one meter per day. Some years this 18-mile long river of ice advances across Lake Argentina, splitting it in two and creating a natural dam. Eventually water behind the glacier rises and, seeking equilibrium, tunnels beneath the glacier. Slowly, the warmer lake waters carve a giant hole through the glacier, leaving only a narrow ice bridge across the top. When the bridge becomes unstable giant chunks of ice begin to calve from the glacier. Towering plumes of water and mist explode from the lake whenever these mini icebergs plunge into the lake, 200 feet below.

Tourists come from all over the world to stand on an adjacent viewing platform to witness the spectacle. Prior to 2004, the bridge had not collapsed for 16 years. Since then, Continue reading →
