A large, ghostly figure appeared in satellite images of Greenland 13 years ago .
The figure was created by a depression in the snow-covered surface, which formed when an underground lake collapsed.
The depression appeared when a subglacial lake rapidly drained of water, leaving behind an underground cavern that swiftly collapsed.
It is still unclear why the lake drained so quickly in 2011 .
