Wonders of Nature The Wave (between Arizona and Utah - USA) A real beauty of red rocks at the border of Arizona and Utah, the wave is formed by sand dunes at the age of 190 million years, which have turned into rocks. This unknown entity is accessible only on foot via a 4-5 mile hike and highly regulated. Author: Vladislava Yoncheva Antelope Canyon (Arizona - USA) The most visited and most photographed slot canyon in the southwestern parts of North America, the Antelope Canyon is located in Navajo land near Page, Arizona. It contains two separate, photogenic rocky gorge, named individually Upper Antelope Canyon - or 'gap' (The Crack) - and Lower Antelope Canyon - or "tirbushonat '(The Corkscrew). Great Blue Hole (Belize) Part of the Reef System, Great Blue Hole lies approximately 100 kilometers from the mainland of Belize City. A large, almost perfectly circular hole approximately one quarter mile (0.4 km), it is one of the most spectacular dive sites around the globe. The water is deep and 145 m depth just gives deep blue color that causes such structures throughout the world to be called 'blue holes'. Crystal Cave of Giants (Mexico) Found deep inside a mine in southern Chihuahua, Mexico, these crystals were formed in the cave totally enclosed in bedrock. They druse, full of spectacular crystals as tall as pine trees, and some are even wider. Color is a translucent gold and silver, with different forms and shapes. Of Blue Lake Cave (Brazil) The region of Mato Grosso do Sul in Brazil (and mostly quiet town Bonito) boasts many exceptional underground lakes: Gruta Lago Azul, Gruta to Misomo, Akuario Natural. World famous "Gruta Lago Azul" (Blue Lake Cave) is a natural monument, whose interior is formed by stalactites, stalagmites and magnificent blue lake. It`s beauty is impressive. The Blue Lake Cave is rich in geological formation but impresses mainly with deep blue water of the indoor pool. Giants Causeway (Northern Ireland) An area of about 40,000 symmetrical basalt columns, the Giants Causeway is the result of ancient volcanic eruption. Located on the northeast coast of Northern Ireland, most of its columns are hexagonal, although some have four, five, seven or eight countries.The tallest are about 12 meters and the solidified lava in the cliffs is 28 meters thick in places. In the 2005 poll of Radio Times listings site for the fourth greatest natural wonder in the UK.

It derives its name from the fact that it is shaped like a tall breaking ocean wave. The total outcrop covers several hectares 'valnistata' part of the rock is about 15 meters high and approximately 110 meters long. One aspect of that is rarely photographed, is the retaining wall about halfway up the cliff. Its contours allow rainwater to be collected through the dam that was built in 1951. Chocolate Hills (Philippines) Consisting of 1268 hills with a perfect conical shape of the same size, located on an area of 50 square kilometers, this rather unusual geological formation, called Chocolate Hills is situated in Bohol, Philippines. There are several hypotheses for the formation of the hills. Including eroded limestone subokeanski volcanism, raising the seabed and modern theories suggest that an ancient active volcano has destroyed one, as it remained huge stone blocks that were later covered with limestone and ocean thrust them forward .
