The Cliffs of Moher (Irish: Aillte an Mhothair)are located at the southwestern edge of the Burren region in County Clare, Ireland.They rise 120 metres (390 ft) above the Atlantic Ocean at Hag's Head, and, eight kilometres to the north, reach their maximum height of 214 metres (702 ft) just north of O'Brien's Tower, which is a round stone tower near the midpoint of the cliffs that was built in 1835 by Sir Cornelius O'Brien

 Half Dome is a granite dome at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. The granite crest rises more than 4,737 ft (1,444 m) above the valley floor.

 

Lysefjord or Lysefjorden is a fjord located in the Ryfylke area in southwestern Norway. The 42-kilometre (26 mi) long fjord lies in Forsand municipality in Rogaland county, about 25 kilometres (16 mi) east of the city of Stavanger. The name means light fjord, and is said to be derived from the lightly coloured granite rocks along its sides.

The White Cliffs of Dover are cliffs that form part of the English coastline facing the Strait of Dover and France. The cliffs are part of the North Downs formation. The cliff face, which reaches up to 350 feet (110 m), owes its striking appearance to its composition of chalk accented by streaks of black flint. The cliffs stretch along the coastline for eight miles (13 km), spreading east and west from the town of Dover in the county of Kent, an ancient and still important English port

Kalaupapa is located on the Kalaupapa Peninsula at the base of some of the highest sea cliffs in the world; they rise 2,000 feet (610 m) above the Pacific Ocean. In the 1870s a community to support the leper colony was established here; the legislature required people with severe cases to be quarantined on this island in the hope of preventing contagious transmission of the disease.
