Looking for the blue hole

A blue hole is a large underwater cave with a hole that opens up at the land’s surface.  Blue Holes are a result of erosion which break downs rock.   Blue holes contain water which is influenced by tides.  Blue holes can contain fresh water, sea water or a mixture of the two.  Blue holes extend below sea level and may provide passage from one body of water to another.  Blue holes are different from cenotes.  Cenotes are inland underwater caverns which are usually found in fresh water.

We took a dinghy brigade to search for the Blue Hole in Robinson’s Bight near Pete’s pub across from Lynyard Cay.  We bummed a ride from our Texas friends Steve & Trisa.

So far below sea level, these blue holes contain some of the harshest environments to be found on earth.  There is no oxygen and no light but these areas can be filled with life forms which have  managed to adapt to such extremes.   Blue holes are extremely dangerous to explore.  Divers wishing to explore must have experience and training.  Most use a thin rope called a guideline which helps to safely find the way out without getting lost.  It is suggested that divers bring several sources of light and breathing equipment to have a back up in cast one fails.  

We have no plans to dive the blue holes and are content with searching for them.
