"Giant's Causeway The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. It is located in County Antrim on the north coast of Northern Ireland, about three miles (4.8 km) northeast of the town of Bushmills. It was declared a World Heritage Site by UNESCO in 1986, and a national nature reserve in 1987 by the Department of the Environment for Northern Ireland. In a 2005 poll of ""Radio Times"" readers, the Giant's Causeway was named as the fourth greatest natural wonder in the United Kingdom. The tops of the"
"columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven or eight sides. The tallest are about 12 metres (39 ft) high, and the solidified lava in the cliffs is 28 metres (92 ft) thick in places. Much of the Giant's Causeway and Causeway Coast World Heritage Site is today owned and managed by the National Trust and it is one of the most popular tourist attractions in Northern Ireland. Access to the Giant’s Causeway is free of charge: it"
"Devils Tower in Wyoming in the United States is about 40 million years old and high. Geologists agree that the rock forming the Devils Tower solidified from an intrusion but it has not been established whether the magma from this intrusion ever reached the surface. Most columns are 6-sided, but 4, 5, and 7-sided ones can also be found. The Giant's Causeway (Irish: ""Clochán An Aifir"") on the north Antrim coast of Northern Ireland was created by volcanic activity 60 million years ago, and consists of over 40,000 columns. According to a legend, the giant Finn McCool created the Giant's"

The formation's sandstone strata are seen in the walls of the Devil's Punchbowl, a scenic gorge within the Devil's Punchbowl Natural Area, an L.A. County park within the Angeles National Forest. Three separate faults have folded and uplifted the formation in view. The Devil's Punchbowl is a large plunging sandstone syncline, where the edges of the formation have been folded upward, and the center has dipped. It was formed by the Punchbowl Fault,"
"Giant's Hole Giant's Hole is a well-known cave near Castleton in Derbyshire, consisting mostly of large passages. It is a stream-way cave, and part of the Karst topography of the area. There is a complex system connecting the cave to Oxlow Cavern and Maskhill Mine to the south. The Entrance Series is easily accessible making it a favourite with novices and groups. The stream that flows into the entrance can be followed through the cave, bypassing three sumps, to the East Canal, Giant's Hole's terminal sump. There are several major tributary passages and a high-level fossil series that provides an"
"during the Paleogene and Neogene periods (66 million to 2.6 million years ago), a period of intense volcanic activity in Northern Ireland. The Giant's Causeway, also from this time period, was created by volcanic eruption. At the Maidens, magma was forced underground through layers of weakness, but never reached the surface. It cooled more slowly, solidifying and leaving a hard rock, relatively resistant to weathering compared to the strata around it and so forming the islands left today. Other examples of nearby sills are Fair Head, the Portrush sill which forms Ramore Head and the Skerries, and the Knocksoghey Sill"
"Giant Rock Giant Rock is a large freestanding boulder in the Mojave Desert directly adjacent to Landers, California, that covers of ground and is seven stories high. Giant Rock is purported to be the largest free standing boulder in the world. Native Americans of the Joshua Tree, California, area consider it to be sacred. A single large room, which was subsequently filled in, was dug beneath the rock and resided in by a prospector named Frank Critzer during the 1930s and early 1940s. Critzer perished in a self-detonated dynamite explosion in this room on July 24, 1942, while being investigated"
"Around the Ulster/Connacht border, the mountains are made from Carboniferous sandstones with softer Carboniferous limestones below them. In central Ulster, the mountains are predominantly made from metamorphic rocks. In the west of both Connacht and Ulster, the mountains are mostly metamorphic rocks with some granite. The Mourne and Wicklow Mountains are mainly granite. Much of the northeast of Ireland is a basalt plateau. An area of particular note is the Giant's Causeway on the north coast, a mainly basalt formation caused by volcanic activity between 50–60 million years ago. The basalts were originally part of the great Thulean Plateau formed"
