Delicate Arch 精致拱門

Delicate Arch can be found in Arches National Park in Utah, USA. The arch stands alone at a height of 52 feet and is considered one of Utah's most important landmarks. In 2002, the Olympic torch passed through this arch to mark the beginning of the winter games.

Wave Rock 波浪巖

This 15-meter high and 110-meter long impressive natural rock formation (形成物) is located in Western Australia. It looks like a large, smooth wave ready to break. Its unusual shape is greatly highlighted by vertical dark streaks of algae (海藻), which grow on the surface of the wave, and by dark black stains (污漬) which change to brown during the dry season.

The Wave 波浪

The Wave is located on the slopes (斜坡) of the Coyote Buttes, Arizona, USA. This incredible formation can be reached by hiking approximately 4.8 kilometers across rugged (崎嶇不平的), trail-less landscape, making the round-trip to and from The Wave a nearly 9.7-kilometer hike that climbs about 107 meters in altitude.

James Bond Island 詹姆斯·邦德島

James Bond Island can be found in Ao Phang-Nga National Park in Thailand. The needle-shaped limestone (石灰石) formation was nicknamed James Bond Island because it was featured in a 1974 Bond film The Man with the Golden Gun.

Devil's Tower 魔鬼塔

The formation known as Devil's Tower can be found in Wyoming, USA. Also known as Bear Tower, the formation is actually the neck of a volcano. It rises dramatically 386 meters above the surrounding terrain (地形) and the summit is 1,558 meters above sea level.

The Giant's Causeway 巨人堤

The Giant's Causeway is located in Northern Island and is comprised of a series of over 40,000 columns made of basalt (玄武巖). Each column is connected and the formation is believed to be a result of volcanic ash. Believe it or not, when this formation was first discovered, scientists argued as to how it was formed. Some thought it was natural, others thought it was manmade—and the mythological thought that perhaps it had been created by a giant!

Bryce Canyon National Park

布賴斯峽谷

One of the most magnificent rock formations in the world is the Bryce Canyon in Utah, USA. It is a national park and despite its name, it is not actually a canyon, but rather a giant natural amphitheater (圓形競(jìng)技場(chǎng)) created by erosion (侵蝕).

PercéRock 皮爾斯巨石

This rock formation is one of the largest natural arches in the world. This spectacular natural arch named Percé Rock (pierced rock) is an island and sheer rock formation in the Gulf of Saint Lawrence, Canada. It is a massive limestone stack (石灰石堆) 433 meters long, 90 meters wide, and 88 meters at its highest point.
