A red-rock stunner on the border of Arizona and Utah, The Wave is made of 190-million-year-old sand dunes that have turned to rock. This little-known formation is accessible only on foot via a three-mile hike and highly regulated.
2.Antelope Canyon (Arizona - USA)
The most visited and photographed slot canyon in the American Southwest, the Antelope Canyon is located on Navajo land near Page, Arizona. It includes two separate, photogenic slot canyon sections, referred to individually as Upper Antelope Canyon --or “The Crack”-- and Lower Antelope Canyon --or “The Corkscrew.”
The Navajo name for Upper Antelope Canyon is Tse' bighanilini, which means "the place where water runs through rocks." Lower Antelope Canyon is Hasdestwazi, or "spiral rock arches." Both are located within the LeChee Chapter of the Navajo Nation.
3.Great Blue Hole (Belize)
Part of the Lighthouse Reef System, The Great Blue Hole lies approximately 60 miles off the mainland out of Belize City. A large, almost perfectly circular hole approximately one quarter of a mile (0.4 km) across, it’s one of the most astounding dive sites to be found anywhere on earth. Inside this hole, the water is 480 feet (145 m) deep and it is the depth of water which gives the deep blue color that causes such structures throughout the world to be known as "blue holes."
4.Crystal Cave of the Giants (Mexico)
Found deep inside a mine in southern Chihuahua Mexico, these crystals were formed in a natural cave totally enclosed in bedrock. A geode full of spectacular crystals as tall as pine trees, and in some cases greater in circumference, they are a translucent gold and silver in color and come in many incredible forms and shapes. The Crystal Cave of the Giants was discovered within the same limestone body that hosts the silver-zinc-lead ore bodies exploited by the mine and it was probably dissolved by the same hydrothermal fluids that deposited the metals with the gypsum being crystallized during the waning stages of mineralization.
5.Eye of the Sahara (Mauritania)
This spectacular landform in Mauritania in the southwestern part of the Sahara desert is so huge with a diameter of 30 miles that it is visible from space. Called Richat Structure --or the Eye of the Sahara-- the The formation was originally thought to be caused by a meteorite impact but now geologists believe it is a product of uplift and erosion. The cause of its circular shape is still a mystery.
