1Danxia Landform Geological Park (China)
The mountains are part of the Zhangye Danxia Landform Geological Park in China. Layers of different colored sandstone and minerals were pressed together over 24 million years and then buckled by tectonic plates.
While the photos are certainly incredible, there could be some photo manipulation going on to make the colors pop a bit more than they would naturally. (Source)
2Abandoned Mines Beneath Yekaterinburg (Russia)
A small portion of the carnallite mines remain in use, but most of the passageways are now closed and off-limits to the public without a special government permit, according to photographer Mikhail Mishainik. (Source)

4Tulip Fields in Lisse (The Netherlands)
From the air, it looks as though a giant toddler armed with a box of super-sized crayons has been let loose on the Dutch countryside–if the lines weren't quite so perfect.
The vibrant blue, red, pink and yellow flowers sprawl as far as the eye can see in Lisse, where farmers hope to make huge profits selling them to florists and supermarkets around the world.
The tulip season begins in March and lasts until August with several shows held across the country, but the flowers are undoubtedly at their most spectacular during April.
The cultivation of flower bulbs began more than 400 years ago. Today Holland produces more than nine billion bulbs every year, of which two thirds are exported overseas. Evenly distributed, this number would allow for almost two flower bulbs for every person on the planet. (Source)

6Caño Cristales (Colombia)
The river appears in many hues–including yellow, green, blue, black, and especially red–which are caused by the Macarenia clavigera (Podostemaceae) at the bottom of the river. (Source)
7Lake Hillier (Australia)
While the causes behind the unusual coloring of other pink lakes – such as the nearby Pink Lake and Senegal's Lake Retba – have been confirmed, the reason for Lake Hillier's color remains a mystery. Some speculate that Lake Hillier's color, like that of the other lakes, is the result of high salinity combined with the presence of a salt-loving algae species known as Dunaliella salina and pink bacteria known as halobacteria. Unlike other pink lakes, which regularly change colors in accordance with temperature fluctuations, Lake Hillier maintains its pink shade year-round. The water also retains its pink hue when bottled.
Whatever the cause, the water does not appear to pose any danger to humans. Though high salt levels might not make for the most comfortable swim, visitors hoping to immerse themselves in Lake Hillier's brilliant pink waters are perfectly safe to do so. (Source)
8Hills of Devecser (Hungary)
In late 2010, the waste reservoir of a Hungarian aluminum oxide plant burst, releasing millions of gallons of caustic red sludge. The meter-high toxic mudslide quickly moved downhill through two nearby villages, Devecser and Kolontár. It buried buildings, poisoned fields and killed 10 people.
Soldiers and volunteers shoveled the muck into trucks and hosed down the streets, but where the sludge had been, every surface was stained red.
When Spanish photographer Palindromo Meszaros visited the disaster site in the spring of 2011, he says, a "feeling of the horror" still lingered. In 2012, he published a collection of the most striking photos from his visit in Fraction magazine. (Source 1 | Source 2)
