Blue holes - underwater passages between lakes and sea - exist on several Caicos Islands. One of the best explored thus far is the Boiling Hole in Lake Catherine, West Caicos.
West Caicos is uninhabited island with a large lake - Lake Catherine - located in its central part. Lake is protected natural area, with many wading birds, flamingos and ducks living in it.
This shallow (1 - 2 m) saltwater lake is connected to the depths of the nearby sea. As the tides in the sea rise up and down, level of the water in the lake also rises up and down - with some delay.
Seawater enters the lake through cave mouths on the lake bed - blue holes. When water enters the lake, it looks like it is boiling above the cave mouth. There are several such blue holes in Lake Catherine, but none by far is that large as Boiling Hole.
It might seem tempting to dive in this cave and go through it, towards the sea. This is though very dangerous due to very strong currents - diver might get struck in narrow place and there would be no way to get him out. If some daredevils would make it - this would require very exact timing and fast action.
Caicos Cave Project, led by Mark Parrish, in 2000 made many dives in the Boiling Hole. Divers managed to get 206 m far in it, until the passage became too narrow.
