They can be formed in different karst processes, for instance, by the rainwater soaking through fractures of limestone bedrock onto the water table. Sea level here has changed: for instance, throughout the glacial age throughout the Pleistocene epoch, some 15, 000 years ago, sea level was considerably lower. The maximum depth of most other known blue holes and sinkholes is 110 meters, that makes the 203 meters depth of Deans Blue Hole quite exceptional. 

Deans Blue Hole is approximately circular at the surface, with a diameter which ranges from 25 to 35 meters. After descending 20 meters, the hole widens considerably into a cave with a diameter of 100 meters. There are various freshwater-filled sinkholes on land which are deeper than Deans Blue Hole.
