1. Lake Retba, Senegal : Lake Retba or Lac Rose is located in the north of the Cap Vert peninsula of Senegal. It got its name due to the Dunaliella salina algae making its water look like strawberry milk shake. Pink color is clearly visible during the dry season. The lake is also famous for its high salt content, allowing people stay on the surface similar to the Dead Sea experience.
2. Glen Brittle, Scotland: Glen Brittle is a large glen in the south of the Isle of Skye, in Scotland. The magic Fairy Pools you see in the picture run down from the mountains into the glen. The area is extremely popular among hikers and mountain bikers. The marvelous lilac slopes above the Fairy Pools are covered with thick forests full of rare plants and animals and who knows, maybe even elves and fairies have found their refuge in this mystical place.
3.Richat Structure : Look into the Eye of Sahara, isn't it impressive? The Richat Structure is a prominent circular feature in the Sahara desert lying in the west-central Mauritania near Ouadane. This structure is a deeply eroded, slightly elliptical dome, 40-km in diameter. Differential erosion of the resistant layers of quartzite has created these high-relief circular cuestas. Its center consists of a siliceous breccia covering an area of approximately 3 km in diameter. Initially, there was a theory that the structure appeared as a result of an extraterrestrial asteroid impact. Looking at the circularity of the Eye, you might be inclined to believe it, but the point is now argued to the favor of highly symmetrical and deeply eroded geologic dome.
4. Chand Baori, Rajasthan : Have you ever seen anything like that? Chand Baori is a famous stepwell in the village of Abhaneri near Jaipur in the Indian state of Rajasthan. It is located opposite Harshat Mata Temple and was constructed in 800 CE. Can you imagine that those 3500 narrow steps in 13 stories extend 100 feet into the ground, making it one of the deepest and largest stepwells in India.
5. Lake Natron, Tanzania : The queer lake's hue is normal for water basins with extremely high evaporation rates. During the dry season, as the water evaporates, salinity level increases to the maximum point and specific salt-loving microorganisms begin to thrive. Some of them produce red pigment colorizing the water and turning it into the Martian landscape.
