Lake disappears suddenly in Chile

Scientists in Chile are investigating the sudden disappearance of a glacial lake in the south of the country. When park rangers patrolled the area in the Magallanes region in March, the five-acre lake was its normal size. But last month they found a huge dry crater and several stranded chunks of ice that used to float on the water. One theory is that an earthquake opened up a fissure in the ground, allowing the lake's water to drain through. The lake's disappearance seems to be part of the continual reforming of the landscape. The lake itself had not been there 30 years ago.
