Plitvice National Park is the largest of its kind in Croatia and the oldest in Southeast Europe. Over thousands of years, water flowing over limestone and chalk created natural dams and eventually, beautiful lakes, caves and waterfalls.
Found in the middle of the Sahara Desert is a deeply eroded bowl, over 24 miles in diameter. The natural formation is so impressive that for a long time, scientists believed it was the site of an asteroid impact.
This lake has a uniquely high salt content. Salt-loving microorganisms thrive and produce red pigment, colorizing the water. For other animals, the salt is deadly and many calcify (effectively turning into stone) after taking a dip in the water.
Underneath the water of Cenote Angelita is another flowing body of water. The river is full of hydrogen sulfate, which is much heavier than normal salt water. When it sinks to the bottom, it forms a flow of its own.
Like the Giant’s Causeway, this cave was formed by lava cooling and fracturing over millions of years. The jagged formations on the outside are entirely nature’s doing.
Aogashima is a volcanic island located 200 miles off the coast of Tokyo. Even more amazing than the view is the geography - there’s a smaller volcano within the volcano island.
This tabletop mountain is one of the oldest mountains on Earth, dating back two billion years when the land was lifted high above the ground by tectonic activity. The sides of the mountain are sheer vertical cliffs, with several waterfalls, making it nearly impossible to climb
Strong ocean currents continually drive sand from the shores of Mauritius into the abyss below, creating this one-of-a-kind underwater waterfall.
Fly Geyser was accidentally created when a well was drilled and left uncapped. Minerals and algae started to rise from the geyser and accumulated to form an alien-like mound.
