For the explorers this was proof that at one time, nearly 65,000 years ago, when the world was in the grip of the last major ice age, the sea level of the Bahamas was up to 150 metres lower than it is today. Over time the limestone of the islands was eroded by water and vast cave networks created. When sea levels rose again about 10,000 years ago some of these collapsed inwards and the Blue Holes were formed.
