 It is in County Antrim, near the Giant's Causeway, which lies between Causeway Head and Benbane Head.
 The nearest settlements are Bushmills and Portballintrae.
Barfold Gorge is a four kilometre long gorge on the Campaspe River at Barfold in Victoria in Australia.
 It is up to 80 metres deep and has two waterfalls, basalt columns and a lava cave.
 It was created by a sequence of four or more lava flows which commenced six million years ago.
 The gorge is on private property, a 246 hectare sheep and cattle farm and is rarely open to the public.
 However, a conservation covenant has been incorporated in the land title.
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic 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.
Tula is a Mesoamerican archeological site, which was an important regional center which reached its height as the capital of the Toltec Empire between the fall of Teotihuacan and the rise of Tenochtitlan.
 It has not been well studied in comparison to these other two sites, and disputes remain as to its political system, area of influence and its relations with contemporary Mesoamerican cities, especially with Chichen Itza.
 The site is located in the city of Tula de Allende in the Tula Valley, in what is now the southwest of the Mexican state of Hidalgo, northwest of Mexico City.
 The archeological site consists of a museum, remains of an earlier settlement called Tula Chico as well as the main ceremonial site called Tula Grande.
 The main attraction is the Pyramid of Quetzalcoatl which is topped by four, four metre high basalt columns carved in the shape of Toltec warriors.
 Tula fell around 1150, but it had significant influence in the following Aztec Empire, with its history written about heavily in myth.
 The feathered serpent god Quetzalcoatl is linked to this city, whose worship was widespread from central Mexico to Central America at the time the Spanish arrived.
The Giant's Causeway is an area of 40,000 interlocking basalt columns resulting from a volcanic eruption on the coast of Northern Ireland.
Shaikh Isa Causeway (officially known as Shaikh Isa bin Salman Causeway, Arabic: جسر شيخ عيسى بن سلمان‎ ‎ ) is a causeway in the Kingdom of Bahrain connecting Busaiteen to the Diplomatic Area, near the Seef area.
 Opened to the public in January 1997, it was constructed to relieve the congestion of the previous bridge connecting Muharraq Island to the mainland Bahrain Island.
 It can be recognized by its triangular white columns, meant to symbolise sails.
A basalt fan structure is a basalt formation composed of columnar jointed basalt columns that have slumped into a fan shape.
Cook's Head Rock is a phonolite basalt rock standing on the Chrystall's Beach expanse closely north of the rivermouth settlement Toko Mouth of South Otago, New Zealand.
 The lower faces of the rock are made up of numerous hexagonal basalt columns suggesting Cook's Head Rock is a former volcanic vent.
The Garni Gorge is situated 23 km east of Yerevan, Armenia, just below the village with the same name.
 On a promontory above the gorge the first-century AD Garni temple may be seen.
 Along the sides of the gorge are cliff walls of well-preserved basalt columns, carved out by the Goght River.
 This portion of the Garni Gorge is typically referred to as the "Symphony of the Stones."
 It is most easily reached via a road that leads left down the gorge just before reaching the temple of Garni.
 Another road leads to the gorge through the village, down a cobblestone road, and into the valley.
 Once in the valley, turning right will lead to Garni Gorge, an 11th-century medieval bridge, and the "Symphony of the Stones".
 Taking a left will lead along the river past a fish hatchery, up to the Khosrov Forest State Reserve, and a little further Havuts Tar Monastery.
