6. An Underwater River Found in the Ocean
Location: Cenote Angelita, Yucatan Peninsula, Mexico
Year Discovered: 2016
Est. Value: N/A
It may seem a little odd to find a river in the ocean. I mean, the ocean is made entirely of water. Be ready for a surprise, though, as off the coast of the Yucatan Peninsula, divers found an underwater river concealed beneath a cloud of poisonous gas. The enormous sinkhole known as Cenote Angelita is the source of the river. It appears that this river empties into the ocean 90 feet below the surface. It is surrounded by a thick layer of hydrogen sulfide, which would kill anyone who tried to breathe it in right away. A tiny skeleton and several petrified trees can be found in the obscene cloud, adding to the unsettling atmosphere. Perhaps the ancient Mayans had a point when they said that the Cenote Angelita was a portal to Hell.
7. Long-lost Ship Found in Namibian Desert — with Gold Aboard
Location: Oranjemund, Namibia
Year Discovered: 2008
Est. Value: $13 million*
The Namibian Desert is arguably the last place you would think to look for a ship. However, that is where the remains of the Bom Jesus were discovered, believe it or not. This Portuguese ship sank off the coast of Namibia five hundred years ago, making it disappear. The Bom Jesus reappeared as the waves off the coast retreated. It was headed for India when a strong storm caused it to capsize, taking with it valuables including copper and gold ingots. After the ship was found by diamond miners, the Namibian government dispatched a team to locate the debris. On the Bom Jesus, two thousand pure gold coins and tens of thousands of pounds of copper ingots were found, nearly entirely undamaged.
