Giant’s Causeway is a remarkable coastal formation on the north coast of County Antrim, Northern Ireland, where roughly 40,000 interlocking basalt columns extend from the foot of the cliffs into the sea. Most columns have a distinctive polygonal shape, created as layers of molten basalt cooled and contracted. The site forms part of the Giant’s Causeway and Causeway Coast UNESCO World Heritage Site and is protected as an important geological landscape.

Maui, both second youngest and second largest of the Hawaiian Islands, is home to the world's largest dormant volcano, Haleakala, meaning "House of the Sun." Last erupting about 200 years ago, it makes up the eastern end of the island. Maui was formed by volcanic activity from Haleakala on the east and the West Maui Mountains to the west. The connecting isthmus between the two spots was formed from joining lava from both and gives Maui its nickname, the Valley Isle.
