One of the greatest mysteries of the Himalayas is a small glacial lake named Roopkund. The lake is located in the Uttarakhand state of India, at an altitude of about 5,029 meters (16,499 feet). The area surrounding the lake is completely uninhabited and the water is a five day treacherous hike from civilization.
In 1942, Roopkund gained the name Skeleton Lake when over 500 human skulls, bones and artifacts were discovered surrounding and inside the ice. These human bones have baffled scientists for decades because historians don’t understand who these people were or what they were doing so high in the mountains.
In 2004, it was determined that the skulls contained severe head trauma. Based on this evidence it has been hypothesized that the people died from a sudden hailstorm.
Probably the most remarkable discovery came after scientists conducted DNA tests on the bones, which proved to have a rich source of DNA material. The bodies were dated to AD 850. This date was 600 years earlier than initially reported.
Remarkably, the experts have found that the dead individuals belonged to two different teams. One team is marked by a shorter stature of the skeletons, while the other human bones are significantly taller. It remains unclear exactly who these people were.
Jellyfish Lake in Palau. Apparently the jellies have lost their ability to sting because of lack of predators in the lake and you can swim with them!
WAIT BUT THAT’S NOT EVEN THE COOLEST PART: These jellyfish carry small populations of algae inside their bodies and derive much of their nutrition from the sugars that the algae produce. The jellyfish follow the sun across the lake each day and rotate continuously, so that the algae are always getting maximum sunlight exposure for photosynthesis. Then at night they dive to deeper parts of the lake so the algae can absorb nitrogen. It’s one of the best examples of endosymbiosis in action and it’s KICKASS.
