These beautiful blue ponds can be seen at the Intrepid Potash mine near Moab, Utah. They are potassium chloride evaporation ponds. “Potash” means salts that contain potassium. Blue dye is added to the water to make its colour so strong. The bright blue in contrast with the red desert helps to optimise the absorption of sunlight and evaporation. As the water evaporates from the pond, crystals of salt and potassium are left behind and then gathered for the production of the chemical.
The Grand Prismatic Spring
The stunning pool of water is located in Yellowstone National Park in Wyoming. It’s the largest hot spring in the United States and the third largest in the world. The colours are caused by the mixture of hot water, algae, and bacteria.
Taal Lake on the island of Luzon in the Philippines has a lake inside an island inside a lake on an island. Pretty crazy, right?

Researchers still haven’t been able to explain these ancient mysteries.
The World Islands
This group of islands built in Dubai is supposed to be a rough representation of the seven continents. If you tilt your head to the left you can kind of see it. The project, conceived by the ruler of Dubai at the time, is made up of 300 islands and sits about four kilometres off the coast.
These colourful lakes are located in the Eduardo Avaroa National Reserve of Andean Fauna in Bolivia. They are on a high plateau called the Andean Altiplano that has volcanoes, hot springs, colourful lakes, and other unique rock formations. The yellow lake that can be seen at the top left corner of the image is called Laguna Colorada. The lake contains white borax islands that contrast with the reddish colour of its water, which is caused by red sediments and pigmentation of algae. Lake Colorada is known for being home to many flamingos.
Davis-Monthan Air Force Base in Arizona also serves as a retirement home for airplanes that are no longer used. Since new technology is always being created, airplanes have a pretty short life and need to be stored somewhere when they are no longer being used. A few of these airplane graveyards were created after World War II because the military had a surplus of aircraft, but Davis-Monthan is the largest.
This giant ring is actually a racetrack. This 19-kilometre circle, located in Italy, is known as the Nardò Ring. The track has four different lanes that are banked to such a degree that a driver doesn’t have to turn their wheel if they maintain a certain speed. They can drive as if the track were a straight line while still making it all the way around.
Giant Stick Figure
This geoglyph, know as the Atacama Giant, is located on a hillside in the Atacama Desert in Chile. It measures a total of 118 metres and was originally built as an astronomical calendar. The spot where the moon would align with the giant would determine the when the crop cycle would start and end.
This light blue body of water isn’t a pond or lake, it’s actually the world’s largest swimming pool, located at the San Alfonso del Mar resort in Algarrobo, Chile. It is a jaw-dropping 1013 metres in length and holds 66 million gallons of water. This pool is so big that there’s a dock located in it and people can take their sailboats out in it on a breezy day.
