Grand Caicos, Bahamas: Grand Caicos, Bahamas. Land areas, shallow banks and reefs, and deep water present striking color differences. A small blue dot on the inner edge of a bank near land, marks a "blue hole". These are sinkholes formed in the limestone bank during the past glacial age, when sea level was as much as 100 meters below today's. Now the sinkhole is submerged under salt water, providing a wonderful playground for scuba divers and biologists.
