Black hole in a universe of gray, this cave entrance marks the convergence of a hundred small channels in the marble plateau. Such outcrops are superb examples of karst topography—exposed, heavily weathered limestone. On Madre de Dios the limestone was laid down millions of years ago as tropical coral reefs. During their month-long expedition the team surveyed five miles (eight kilometers) of caves, none of which had ever been explored.
