In the entrance series of a cave in Gunung Mulu National Park, Borneo called Whiterock, Keel passage contains unusual speleothems and cave formations. Paleoclimatologists Prof. Gina Moseley (pictured in red) and Dr. Nele Meckler admire the 'keel' shaped formations draping down from the ceiling of the cave. It is unknown exactly how these have formed. Many believe that wind blowing through this low passage has blown the calcified drip water in such a way, forming wide but thin shapes similar to a fin or a keel.
