What makes you want to take your clothes off and jump in nature’s pools? Factors probably include beautiful bright blue color and calm waters. The beautiful, bewildering, and mysterious relief features are the dominant features of the Earth. Earth is covered with more than 70 percent of water and it is one of the essential components to humans and other life forms. However, don’t ever get fooled with such beauty for you may not know what’s underneath some of these beautiful bodies of water.
It is a freshwater lake, but the water of the lake contains a high gas concentration which is measured by 55 billion cubics of methane at the bottom. Which is what makes it possibly deadly as it is over 250 cubic kilometers of carbon dioxide and 65 cubic kilometers of methane gas. Lake Kivu is a shared resource between Rwanda and the Democratic Republic of Congo. It sits on upon a rift valley that is slowly being pulled apart, causing volcanic activity around the area. It’s also known for its maximum depth of 485 meters. For now, the pressure of the water is twice as high as the pressure from the gases which means the risk of eruption is low and the lake is still a safe place to swim in.
The Drake Passage is the body of water between South America’s Cape Horn, Chile and the South Shetland Islands of Antarctica and is considered one of the most troubled waters in the world because of 80 miles per hour winds, poor visibility, and strong currents. It connects the southwestern part of the Atlantic Ocean with the southeastern part of the Pacific Ocean and extends into the Southern Ocean. It is the shortest route crossing from Antarctica to any other landmass. It is known for its convergence character because is situated in a zone of climatic transition which is characterized by icebergs, huge waves, and plagued by gale-force winds. It was the only known passage before the construction of the Panama Canal.
It is also called the Red River because of its appearance. Probably anyone will think that something’s not right when a river has deep red water. Its water is very dense (due to metal contain), highly acidic with a pH of 1.7 – 2.5. and low oxygen content that made a home of extremophile anaerobic bacteria that dwell in the water. The Rio Tinto is also rich in heavy metals like gold, silver, and copper which made it a popular river among ancient cultures throughout history. Now, due to 5000 years of mining pollution, the river became an extreme environment, breeding chemolithotrophic organisms such as iron-oxidizing bacteria and sulfur-oxidizing bacteria. The river originates in the Sierra Morena mountains of Andalusia.
Located in the Morne Trois Pitons National Park, Dominica‘s Boiling Lake is the world’s second-largest hot spring and looks like it took its hotness to an entirely higher level. The water temperature along its edges 82 to 92 degrees Celsius (180 to 197 degrees Fahrenheit) and the center’s temperature is – forget about it. Measuring the center of the lake’s temperature isn’t possible since it continues to boil and going near its center could be risky. It is said that this is located in the vicinity of the volcano, which emits steam and gases escaping molten lava below. Swimming is strictly prohibited.
Just outside Washington D.C., the Potomac River Gorge is a 14-mile stretch that extends from the Key Bridge in the District of Columbia north to the Great Falls of the Potomac. The gorge is a popular site for outdoor activities like kayaking, boating, fishing, and hiking enthusiasts. But there is no doubt that this river is deadly. The water rushing through the Potomac River creates roiling underwater currents in even the calmest-looking places. The river’s currents can quickly capture swimmers, waders, and people who slip and fall into the water. Never ever get fooled by its placid look.
The Blue Hole is a diving location on the southeast Sinai, a few kilometers north of Dahab, Egypt on the coast of the Red Sea. The Blue Hole is a submarine sinkhole, with a maximum depth within the hole of just over 100 m. It has been a divers dream to dive on this site just like the challenge of climbing Everest or Kilimanjaro appeals to mountaineers. A testament to its nickname the ‘Divers’ Cemetery’, is one of the deadliest diving sites in the world because it’s the 400-foot deep cave and is also nitrogen narcosis prone.
Unfortunately, the reason why Citarum River is deadly is because of something man-made – garbage. The place is so filled with non-biodegradable waste and harmful chemicals that it’s known to be the world’s most polluted river. There are over 200 textile factories lining the river banks and the dyes and chemicals like arsenic and mercury are all dumped in the river. Combine here the millions of residents who treat the river as a huge trash bin and for sure no one’s crazy enough to drink water from this dumpsite.
It’s a crystal clear water lake, Jacob’s Well is known to be one of the world’s most dangerous diving spots. Descending 9 meters down the well will get you to the first chamber. Go further down and you’ll reach the second chamber which is 24 meters below the surface. This is where the danger begins because of a passage that looks like an exit but instead can trap the diver. There are also third and fourth chambers that await the diver who’s brave enough to reach the deeper parts of the well. Jacob’s Well has a total depth of around 40 meters.
Great Blue Hole
The Great Blue Hole is a giant marine sinkhole off the coast of Belize. It lies near the center of Lighthouse Reef, a small atoll 70 km from the mainland and Belize City. The hole is circular in shape, 318 m across, and 124 m deep. It is a giant submarine sinkhole formed by quaternary glaciations. It periodically gushes huge, powerful columns of water up into the air, which can cause serious trouble for divers and boats alike.
