'In March we patrolled the area and everything was normal,' Juan Jose Romero from Chile's National Forestry Corporation, Conaf, said. 'We went again in May and to our surprise we found that the lake had completely disappeared. All that was left were chunks of ice and an enormous fissure.'" The current theory is that an earthquake opened the ground and allowed the lake to drain. Looks like global warming is off the hook this time around.
