Fascinating Basalt Columns - Iceland

Iceland is probably the best place to find many beautiful basalt columns. At least where the distance between them is relatively short. The basalt column is a magnificent rock formation that has inspired artists and designers and has sometimes been elevated to a divine level as was the case with our famous church Hallgrímskirkja in Reykjavík.

Fairy Circles - Namibia

Across the arid grasslands of the Namib Desert lies an eerie sight: millions of circular patches of land void of plants, each between 2m and 15m in diameter, arranged in a honeycomb-like pattern across 2,500km of land. These disks of bare soil, known as fairy circles, pockmark the landscape in Namibia, as if giant moths ate through the vast carpets of grassland.

Penitentes - Argentina

These ice spikes, called penitentes, form in high altitudes, where sunlight turns ice directly into water vapor, rather than melting it to water. Sun beams vaporize small dimples in the snow's surface. Then, the uneven surface directs sun into the dips and away from the peaks, exacerbating the trend. Penitentes can grow as tall as 15 feet.

Ankarana - Madagascar

The topography of Ankarana is characterised by limestone emerging from a basaltic plain 50m above sea level, forming the tsingy (sharp limestone karst pinnacles). Numerous underground caves and canyons traverse the massif. Four major rivers flow through the reserve: Besaboba eastward, Ankarana from the north, Antenan'Ankarana and Mananjeba from the south. The first three are underground rivers whose specific watercourses still remain unknown.

Bryce Canyon - USA

Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau. Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rocks. The red, orange, and white colors of the rocks provide spectacular views for park visitors. Bryce Canyon National Park is much smaller, and sits at a much higher elevation than nearby Zion National Park. The rim at Bryce varies from 8,000 to 9,000 feet (2,400 to 2,700 m).

Inca Bridge - Argentina

Hanging 2,719 meters above sea level, ‘Inca Bridge’ is a fantastic natural bridge that shines in between the Andes Mountains. The bridge is located above the Cuevas River, and there are two stories that tell how it was formed: a poetic Inca tale and a more scientific geological explanation. The Inca legend tells how a famous Inca heir was terribly ill and the gods advised him that he could only be cured by drinking from the magical medicinal water at the end of the Inca Trail. They walked all the way from Peru, and when they finally got to the site they realized that they had to cross to the other side to access the water. They made a ‘human bridge’ to save the heir’s life, however the helpful Inca people were sadly petrified forever as they formed the ‘Inca Bridge’.

Glacier Bay - Alaska

Sawyer Glacier is an active tidewater glacier, which means it "calves" or breaks off. Pieces of ice anywhere from the size of a small car to a cruise ship fall off the face of the glacier and hit the water with a thunderous roar. No matter how many times you visit Sawyer Glacier, it is always a thrill to see a calving event. The water at the end of the fjord is nearly 600 feet deep and when an underwater calving takes place, the ice remains intact, giving us Alaska's largest icebergs. In other glacier areas, the calved ice generally crumbles. Underwater calvings surface like giant submarines that rise over 250 feet and then settle into the water like large, blue ships.

Fly Geyser - Nevada, USA

This alien looking geyser on the edge of Black Rock Desert is actually human-made. But it wasn’t put there on purpose. The Fly Ranch property is located in Nevada’s Hualapai Geothermal Flats, an area known for its unique geothermal pools. There are three geysers on the property. The first, known as The Wizard, was created more than 100 years ago, during an effort to make the desert usable for farming. While drilling a well, workers hit geothermal water that was about 200 degrees Fahrenheit. Because the water was not suitable for agricultural use, this geyser was left alone. A 10-12 foot calcium carbonate cone formed as a result of the water’s mineral content.

Blood Falls - Antartica

In Antartica, there are the famous Blood Falls—a blood-red waterfall pouring out of the Taylor Glacier in the McMurdo Dry Valleys. Scientists and geologists first thought the red color is because of algae, according to Atlas Obscura. Research by the University of Alaska Fairbanks, however, found the red color is thanks to oxidized iron in the brine saltwater. We see the falls thanks to a fissure allowing the water to flow from the small, trapped body.

Eye of the Sahara - Mauritania, Egypt

The Eye of the Sahara, also known as the Richat Structure, is a geologic dome containing rocks that predate the appearance of life on Earth. The Eye resembles a blue bullseye and is located in Western Sahara. It is visible from space and has been used as a visual landmark by astronauts. Geologists believe that the Eye's formation began when the supercontinent Pangaea started to pull apart.

Travertine Terraces - Turkey

Travertine, forms as a result of calcium carbonate precipitation from geothermal waters, according to the University of Waikato. The travertine builds up forming terraces over time. When hot water full of carbon dioxide flows through limestone, it dissolves. It carries calcium carbonate to the surface of the travertine, per Atlas Obscura. Still, more research shows there might be other reasons for their formation. Bacteria in the water could catalyze the minerals, forming the terraces, according to Science Magazine.

Dallol Volcano - Ethiopia

The Dallol volcano, or rather the Dallol hydrothermal field is located in a remote part of the northern Danakil Depression in NE Ethiopia. It is the lowest known sub-aerial volcanic area in the world. Dallol is one of the world's most spectacular landscape: a vast area of uplifted thick salt deposits affected by intense fumarolic activity, probably caused by an active volcanic system beneath several kilometers of evaporation salt deposits. Dallol is said to be the hottest place on the planet, with average annual temperatures well above 30 deg C.

Nambung National Park - Australia

The pinnacles in Australia's Nambung National Park are primarily limestone outcroppings richly endowed with such marine organisms as corals and mollusks. During the early Pleistocene, the sea washed sand, coral, microorganisms, etc. onto the Pinnacles Desert, which over tens of thousands of years formed limestone. Eventually, wind and rain eroded all but the most resistant rock, leaving behind these remnant pillars. It should be pointed out that the exact manner of their formations is still being debated. The tallest pinnacles here are about 10 ft (3 m) in height.

Emerald Ice on Bakail Lake - Russia

This vast white landscape is covered in a blanket of stunning ice sculptures which are creations of nature. The naturally formed ice blocks, named ice hummocks, have been created due to the extreme weather conditions. Freezing temperatures and fierce winds causes fresh ice and ice floes to move, resulting in these picturesque blocks. Also known as 'Ice Hummocks' - These ice hummocks, created through a combination of extreme winds and cold temperatures, can reach a height of 15m (50ft).

Fairy Chimneys - Turkey

The fantastical 'fairy chimneys' found in central Turkey's historic Cappadocia region were formed by a collision of the natural and the man-made. The landforms were created when volcanoes deposited mounds of soft, porous rock called tuff, which was later covered with hard basalt. In the 10th century (though possibly starting up to 5,000 years ago) humans excavated the tuff to create caves and catacombs that could fit thousands of dwellers. Through not only the astonishing ruins but the many 'cave hotels' hewn into rock in the city of Göreme, the memory of those ingenious city planners lives on.

Godafoss - Iceland

Goðafoss Waterfall is nicknamed the “Waterfall of the Gods.” Some believe that the name comes from the fact that the waterfall is god-like in beauty. Goðafoss is one of Iceland’s true pearls and one of the biggest waterfalls in Iceland. Its fed by the river Skjálfandafljót which runs in a 7000-year-old lava field from the Trölladyngja volcano. The waterfall flows over a 30-meter (98 ft.) wide horseshoe-shaped rock that rises in the center separating the waterfall in two. One section is about 9 m. (30 ft.) and the second is 17-meters (55 ft.) high.

Rainbow Mountains - China

The formation of the mountain began 55 million years ago. When the flat sandstones collide and uplifted the mountains. With wind and other natural events in time, the overlying layers went away, and the mineralogy and chemistry of the mountain began to shape today’s form of the mountains, also the colors.

Also the underground waters have a role while creating the colors. The water’s move through the sandstones revealed the minerals between the grains and cemented them. The first color that was occurred was red. The iron oxide coating and cementation between the sandstones made the red color. Also rains helped it to happen.

After red colored stones, brown, yellow and black stones started to occur just like the same process. With oxidized limonite, goethite, magnetite, iron sulfide, sulfur and more chemical reactions created other colors

Lencois Maranhenses - Brazil

The park's white sand dunes and shimmering lagoons sprawl across 580 square miles of the northern Atlantic coast, near the Amazon Basin. two rivers run through the national park, which deposit sediment as they flow toward the Atlantic Ocean. It is this sediment that actually creates the majestic dunes that give Lençóis Maranhenses National Park its name, however the rivers are not soley responsible. During the region's dry season, winds from the Atlantic push inland, picking up the sand and tossing it into rolling dunes. Some of the pools — which come in varying shades of green, blue, and black – can be several feet deep. Lagoa Azul and Lagoa Bonita are two of the biggest lagoons in the park.
