25 Strangest Geological Formations On Earth

Posted by on July 26, 2013

Earth is a big place with a lot of unique flora and fauna, and as strange as it can already be there are still new geological discoveries being made every day. While there are probably numerous places that could have been included on this list, we were forced to narrow it down to the 25 strangest geological formations on Earth.

10

Skaftafell – Iceland

Skaftafell is a preservation area in southeast Iceland. The landscape is very similar to some of the Alps, but it has been formed over thousands of years by a combination of volcanoes and glaciers. It is known for its unusually agreeable climate and diverse geography.

Puerto Princesa Underground River – Philippines

Located about 50 kilometres north of the city centre of Puerto Princesa in the Philippines, this river is filled with complex rock formations, strange marine life, and massive caves. Deeper areas of the underground river are almost impossible for visitors to explore due to a lack of oxygen.

8

Yellowstone – Wyoming

Surrounded by canyons, rivers, lakes, and mountain ranges, the Yellowstone Caldera is home to the largest super volcano on the continent. Grizzlies, free-ranging herds of bison, elk, and wolves are some of its many inhabitants. Possibly its most notable feature is Old Faithful, known as the most predictable geographical feature on Earth, as it erupts almost exactly every 91 minutes.

7

Arches National Park – Utah

Arches National Park is a U.S. National Park in eastern Utah. It is known for preserving over 2000 natural sandstone arches, including the world-famous Delicate Arch, in addition to a variety of unique geological resources and formations. Forty-three arches have collapsed due to erosion since 1970.

6

Richat Structure – Mauritania

Also known as the Eye of the Sahara, this hypnotizing formation can be found in the desert of western Mauritania. Dutch Astronaut Andre Kuipers took this photo from the International Space station. Although no one is exactly sure of its origin, it was initially interpreted as an asteroid impact structure because of its high degree of circularity. Today, however, it is speculated to be a highly symmetrical and deeply eroded geologic dome.

5

World of Ice Giants – Austria

The Eisriesenwelt is a natural limestone ice cave located in Werfen, Austria, about 40 km south of Salzburg. It is the largest ice cave in the world, extending more than 42km and is visited by about 200,000 tourists every year.

4

Babele – Romania

Babele, meaning “old women”, is the name for an area on the Bucegi Mountains plateau in Romania. It is one of the most popular tourist destinations in the country and the name comes from various mushroom shaped rock formations scattered across the landscape.

3

The Wave – Arizona

The Wave is a sandstone rock formation located near the Arizona-Utah border on the Colorado Plateau. It is famous among hikers and photographers for its colorful, undulating forms, and the rugged, trailless hike required to reach it.

2

Pancake Rocks and Blowholes – New Zealand

The Pancake Rocks are a heavily eroded limestone area where the sea bursts through several vertical blowholes during high tides. They are presently explorable by a number of walkways winding through the rock formations.

Fingal’s Cave – Scotland

Fingal’s Cave is a sea cave on the uninhabited island of Staffa in Scotland. Its size and naturally arched roof, and the eerie sounds produced by the echoes of waves, give it the atmosphere of a natural cathedral. The cave’s Gaelic name, An Uaimh Bhinn, means “the melodious cave.”
