Santiago, Chile. In less than 24 hours Lake Cachet II in Chile’s southern Patagonia vanished, leaving behind just some large puddles and chunks of ice in the vast lake bed.
The lake’s water comes from ice melting from the Colonia Glacier, located in the Northern Patagonian ice field, some 2,000 kilometers south of the capital, Santiago.
The glacier normally acts as a dam containing the water, but rising temperatures have weakened its wall. Twice this year, on January 27 and March 31, water from the lake bore a tunnel between the rocks and the glacier wall.
