It's a layer of hydrogen sulfide, a toxic gas created by bacterial colonies and decaying organic matter. For example , Angelfish Blue Hole in the Exuma Cays is predominantly a lens-based cave that connects through several passages to a major local fault line cave system. On previous dives, Kakuk had extended the line 2,000 feet farther, but at my level of experience, we've come as far as he'll allow. The stalactites, stalagmites, columns, draperies, and flowstones are easily the most beautiful in the Bahamas. Several water filled sinkholes though are deeper. Most Open Water Certified divers should only descend to depths around eighty feet.
Blue Hole by Treasure Cay Airport: Just before the airport turn left on a dirt road that runs about 300 yards from the end of the runway. It has also been said that there are eyewitness accounts of the Lusca killing people who get too close to its lair, even dragging people off land and down into the caves. Although lacking a lower jaw, the yellowed skull has molars on both sides and a single front tooth. Groping blindly and using my safety reel to search in a spoke pattern, it took me 12 interminable minutes to find the line. Lucayan bones are just part of the tapestry of blue holes, says Nancy Albury, project coordinator at the National Museum of the Bahamas, whose passion for blue holes centers on the animal remains they contain—the remarkably preserved fossils and bones of crocodiles, tortoises, bats, owls, beetles, and other species that thrived in the Bahamas before the Lucayan occupation.
Many blue holes have built up docks with ladders or stairs, but others require more extreme measures. Other product and company names shown may be trademarks of their respective owners. It sometimes has many of the same characteristics as a colossal octopus, but has also been described at different times as having multiple heads, dragon-like features, or even appearing as a vaguely described evil spirit. Remember, stalactites need to cling tightly to the ceiling above. The diameter of the top entrance ranges typically from 25—35 metres 82—115 ft Dean's Blue Hole to 300 metres 980 ft in Belize. As living laboratories, inland blue holes are the scientific equivalent of Tut's tomb. Guided diving and transportation is provided to both inland and ocean caves depending on tides, weather, and the clients preference.
Kakuk has explored North Passage about 1,300 feet out from the central shaft, edging ever closer to the next blue hole to the north, and he's pushed even farther into South Passage. After the boat was dragged for some distance, the line went slack and the trap was pulled up. This blue hole is not for children and not for the faint of heart. There is an eerie quality of intention—the vaulted corridor seems more designed than randomly occurring—and I'm reminded simultaneously of the outer walls of Mycenae and the gallery in Khufu's Great Pyramid. It's mesmerizingly beautiful and in Hi Def. He is assisted by diver Brian Kaluk and project coordinator Nancy Albury. The dive experts of Bahama Divers venture to the remarkable Lost Blue Hole approximately four times per week.
I have not personally visited all of them, but I have the directions from a reliable source! These sinks are where the term blue hole actually comes from, as the water appears to be incredibly blue when observed from the air. Some 500 feet into South Passage, we reach the end of the main line, tied off to a bollard of calcite at a depth of 130 feet. Deeper into the caves, the web of passages disperses the velocity of the currents. Around Exuma there are a number of blue holes that are connected to inland sinkholes. Their perimeters make for some interesting snorkeling. Explorer Fred Davis is currently surveying Dans Cave, and estimates over 17,000 feet of passage in a series of 26 very large rooms.
This means that currents in some of these caves can be so strong that diving during the wrong part of the tidal cycle can have disastrous results. No data is shared unless you engage with this feature. This color is created by high transparency of water and bright white carbonate sand. Choose from Lynx Air or Trans Caribbean Air in Fort Lauderdale and enjoy a 90 minute journey across the Gulf Stream and over the brilliant blue waters of the Bahamas. Once you arrive, for example, the picnic can begin. Long ago before we wrote stuff we drew pictures ofvwe saw and told stories. Local cave diver, Tim Higgs, explores the beautifully decorated passages of Dan's Blue Hole.
Stargate's entrance lies on land that's been in her family for generations. The surface water in some blue holes can be dark, tannin or even muddy, but the deep water below is usually very clear. Then Kakuk directs my attention to a Barbouria shrimp, a reddish, two-inch crustacean with long, bowed antennae for sensing prey in the darkness. Great Abaco Island, the northernmost island in the Bahamas, is a short, 40-minute flight from the east coast of Florida, and for the last 50 years has been regarded predominantly as a yachting and fishing paradise. After 18 minutes of decompression and a total dive time of 65 minutes, we emerge into the warm Bahamian air. As we fin deeper into South Passage, the only sound is the rhythmic hiss of our regulators and the rumble of our exhaled breaths. But the lure of virgin cave is strong, and many of these divers still return every few years to pick up where they left off, or to check out caves that they just didnt have the time to dive on previous trips.
It seems that the decisive factor in the use of this term is the beautiful deep blue color of water in these formations. Known on land as swamp or sewer gas, hydrogen sulfide in higher doses can cause delirium and death. Above soars a vaulted, triangular ceiling; below, a floor of impenetrable darkness. Some cryptozoologists have suggested it is merely a giant octopus that has been misidentified. They gathered data that promise to deepen our understanding of everything from geology and water chemistry to biology, paleontology, archaeology, and even astrobiology—the study of life in the universe. She is aided by Nikita Shiel-Rolle, a Bahamian cave diver and marine science graduate student at the University of Miami. Bottomly's is an inland Anchialine blue hole, that is connected by a labyrinth of passages to Mystery cave, which is a very tidally effected marine blue hole.
