JAMAICA FIRE WATER: Located at the end of a looping dirt road just outside of the Runaway Bay roundabout in St. Ann, Firewater pond is said to be one of Jamaica's best-kept local secrets. Housed in a makeshift bath area, the pond contains natural gases which create floating flames on top of jacuzzi-like, bubbling waters when lit. @Atlas Obscura
DEVIL'S MARBLES: A symbol of Australia and the outback, the conservation area surrounding these spans 4500 acres and is home to hundreds of rounded rocks. Millions of years of erosion and the elements caused the granite rocks to end up with these rounded edges, with solarization causing some to split completely in half. A few people still believe the giant rocks are fossilized eggs of the Rainbow Serpent... we'll withhold judgement on that one.
JÖKULSÁRLÓN: go to Iceland's largest lagoon and you'll stumble upon these amazing multi-coloured icebergs, though as nearby glaciers melt this landscape becomes more fragile; it's formed entirely from glacial melt. It looks so good they used the view in 'Batman Begins'...
MORNING GLORY POOL: originally known as 'Convolutus', the colour is created by thermophilic bacteria that thrive in the pool's hot temperatures. Being a major tourist stop in Yellowstone means that the pool has suffered from inconsiderate visitors who've thrown trash into it for more than a century, but following seismic activity it erupts in a geyser, and it's hoped that this may help clear the pool of trash.
