Natural caves have always been among the most captivating contributions of nature to the beauty of the world. Some are more interesting than others because of the story behind them. Never the less, every cave is an opportunity to better understand a place and how things evolve in the natural world.
Dan yr Ogof
Dan yr Ogof is the main feature of a show cave complex known as the National Showcaves Centre for Wales. It is located in Brecon Beacons National Park. This 17 km.- long cave system is a major tourist attraction. However, only the first section is open to the public while the rest can only be visited by bona-fide cavers. In one poll, the Dan yr Ogof was chosen as the greatest natural wonder of Britain.
The cave was first explored in 1912 by two brothers who stopped upon encountering a tight crawl. This tight crawl was eventually explored by other cavers, thereby continually extending the stretch of cave system at each try. Bones of humans and animals have been found in one chamber of the cave system.
Cave of the Crystals
The main attraction of the Cave of the Crystals or Giant Crystal Cave consists of the giant selenite crystals, some of which are the largest crystals ever found on earth. It can be found 300 meters below the surface in Naica, Chihuahua, Mexico and is essentially a cave connected to the Naica Mine. Crystals were able to grow to these immense sizes because of the very stable temperature of the mineral-rich hot water contained in the hollow space of the cave which has remained filled for about 500,000 years.
It was in the year 2000 that this cave was discovered by miners excavating a new tunnel. Further exploration is being hampered because of the necessity to destroy some crystals in the process, which of course no one wants to do. There are plans to reseal the cave to allow the water to rise and let nature takes it course once again.
Fingal’s Cave is a sea cave located on the island of Staffa which is uninhabited. The island can be found at the Inner Hebrides of Scotland. It derives its name from a hero in an epic poem .
Its structure is made up of hexagonally jointed basalt columns. The size and arched roof gives a cathedral-like atmosphere together with sounds produced by the wave echoes. This is why it is also often referred to as the “melodious cave”.
