A glacial lake in the Andes has disappeared mysteriously, prompting local geologists to head to Bernardo O'Higgins National Park in Patagonia, Chile, to find out what happened.

The answer is very simple, its happend about 100 times during a summer in Greenland every year, a glacial lake disappers.

The lake was in the front of a glacier, and there is permafrost in the underground, the floor of the lake simply melted the permafrost and I have from other sources that the area had a lot of caves in the underground, so now you have a empty lake and a cave full of freshwater. The sediment in the lakebotton are ground pulp from the rocks rubbet of by the glaciers movement to the edge.

When the ground pulp is drying up it looks like cement and can be transported by the wind into the ice again as a duststorm and black ice melting faster than white ice.

Perhaps some permafrost melted beneath the lake, opening a preexisting channel. Global warming??

I suspect earthquake did the trick. Earthquake break open the ice floor, which had an underground opening, possibly a cave.

I suspect the cave had a vacuum which sucked the water at much faster rate than expected.
