Rookpund, India. When British soldiers discovered hundreds of skeletons on the shore of a tiny glacial lake high in the mountains in 1942, they decided that they had stumbled upon the victims of mass execution, say, by the Japanese. But a subsequent analysis showed that the skeletons were more than a thousand years old, and they all died from the hail that passed here a long time ago - they were simply hammered with huge pieces of ice.
Nyos, Cameroon. Typically, volcanic lakes release small amounts of carbon dioxide, but it has been collected in Nyos for decades. Until August 21, 1986, a limnological catastrophe occurred - the accumulated gas escaped and killed all life at a distance of 25 kilometers from the lake. In a matter of minutes, 1, 746 people and 3, 500 animals died.
Pener, Louisiana. Lake Penère was fresh and not very deep - about three meters - as long as Texaco representatives, who were looking for oil under the bottom, had not punched a hole in the salt mine. A drilling rig, barges, some houses, and generally everything that was on the shore sucked into the whirlpool. Miraculously, none of the people died. Now Pener is filled with salt water from the Delcambre canal and reaches a depth of 400 meters.
Baotou, China. This artificial lake arose due to the active extraction and processing of minerals used in electronics and touch screens in particular, as well as many "green" technologies like wind turbines. Ironically, this is the most polluted lake on Earth, essentially consisting of toxic waste.
Natron, Tanzania. The red waters of Lake Natron carry an unimaginable amount of salt and alkali, killing and turning to stone most of the animals and birds that accidentally fall into them. Oddly enough, this terrible phenomenon does not affect small flamingos, for which the lake is the only breeding place. No predator dares to attack them in this “damned” place.
Kawah Ijen, Indonesia. This is the largest acid lake in the world: it contains sulfuric and hydrochloric acids of high concentration. Approaching Ijen Lake without a gas mask is not recommended. This, however, does not stop local residents extracting sulfur from the mine on the side of the volcano.
Pitch Lake, Trinidad. Pitch Lake is a bitumen lake or, simply, a tar pit, the largest source of natural asphalt in the world. The surface of the lake is so dense in places that you can walk on it, although this is not strictly recommended - this is how ancient animals like giant sloths got into the tar. Their bones are pulled out of bitumen to this day.
Lost Lake, Oregon, USA. Sometimes lakes arise on their own, and sometimes they disappear. One of the Oregon lakes disappears every summer, leaving a flowering meadow, and in the fall returns to its place. The reason is lava tubes running under the bottom, which are filled with water in the summer, and in the fall they give off excess rainfall to the lake.
Yellowstone Lake, USA. At its bottom is a small dome - the highest point of a supervolcano. If an eruption begins, the consequences will be felt not only in the United States, but throughout the world. A 10-year winter will leave us not many chances of survival. Was the release from Lake Nyos scary? Just wait for Yellowstone to tear.
Gafsa, Tunisia. In 2014, several shepherds traveled along the usual route through the desert. Suddenly, they stumbled upon a huge lake that appeared out of nowhere. Three weeks ago, this site was dry, but the groundwater escaping from the fault in the rock corrected the situation. The lake, however, was soon overgrown with algae.
For example, every traveler should be aware that there are lakes that can destroy all life within a radius of several tens of kilometers from themselves. Or turning random bathers into stone. What to do, nature is not always favorable to us.
