Jacques Cousteau once called the Great Blue Hole in Belize one of the Earth's best places for diving. But you must dive at your own risk. The tides turn the Great Blue Hole into a vortex that draws everything on the surface in and the ebbs make it spout huge columns of water. Both can be extremely dangerous.
Jacob’s Well is a crystal clear 30-foot deep natural well. It is also one of the most dangerous diving sites in the world and many have lost their lives diving there. At the bottom of the well, there are several openings for other caves that are impossible to get out of and some never do.
Did you know that Lake Michigan is known as ‘The Bermuda Triangle of the Great Lakes’? There have been many horrible plane crashes over the lake that seem to be a mystery. Go ahead and fly over it if you dare.
Lake Natron is one of the saltiest and most alkaline lakes on Earth. It is covered with a red crust of salt and the water temperature can reach up to 120°F. The salinity and the temperature make it unlivable, although three different kinds of fish have been able to adapt and live there despite the extreme conditions.
The Blue Hole is one of the most dangerous places for diving in the world. There is no public record of how many deaths, but divers in the area suggest that as many as 200 people have died there in recent years. The cause of death is usually nitrogen narcosis or insufficient air capacity upon ascent.
The carbon dioxide that is emitted from the fissures at the bottom of Horseshoe Lake can kill pretty much anything. The lake is responsible for at least four human deaths as well as all the trees surrounding it. Trees are not safe for up to 100 acres around the lake.
Boiling Lake can heat up to 198°F with no warning at all. While it may seem like a regular lake, there is no swimming allowed in the lake and authorities like to keep people far away from it. Hot air spurts from beneath the ground can cause the lake to start boiling in a matter of seconds and by the time you try to get out, it will already be too late.
So, I guess the name really lives up to its reputation.
The Tinto River is saturated with copper, iron, and heavy metals. Because of this, its acidity level is as strong as stomach acid. The levels are powerful enough to kill any fish that tries to get near it. Any humans should stay away too.
If you try to pass through Drake Passage, you will have many obstacles in your way. Icebergs, wind speeds reaching 80 miles per hour, strong currents, and poor visibility are just a few of the things that may get in your way. The passage is considered to be a ship cemetery and only the most skilled will survive.
While it may seem like a peaceful lake, this body of water is lethal. There are layers of CO2 in it, as well as 55 billion cubic meters of methane at the bottom. Any earthquake could come along and cause an explosion that could wipe out the entire surrounding area.
The Blue Lagoon in Derbyshire was once a very popular swimming spot before its water became almost as toxic as bleach. Signs close to the shoreline warn that the water contains dead animals, human waste and abandoned cars. Even though it is extremely dangerous and has a pH level of 11.3, people still take a dip in it!
Somalia’s coast is infamous for piracy. Pirates in the area often fire with automatic weapons on any ships that are in their way. They will target anything that floats: yachts, freighters, sailboats, mammoth oil tankers. They once tried to take over an American naval ship by mistake!
The Potomac is very deceptive. It looks calm and tranquil, so people jump in to take a dive. Unfortunately, the river has a very high undercurrent, with a lot of rocks at the bottom. Because the water is not clear, you can't see what is really below the surface and this could end in death.
If you love your dog, don't bring them anywhere near Oregon's Tualatin River. Close to a dozen dogs die each year from being exposed to toxic blue-green algae. Find another place for them to swim because this river could kill them.
The rivers of Johannesburg as filled with E.coli bacteria. While they keep pumping money on waste management, it is still a major problem. The E. coli count is mainly caused by grey water and run-off from informal settlements in the surrounding areas.
