The Marble Caves of Rio Tranquilo

The Marble Caves of Rio Tranquilo

Located in the Coyhaique province, Chile, the Marble Caves are some of the most impressive attractions of Patagonia.
Las Cavernas de Marmol, as the Spanish call them were created by the clear waters of Rio Tranquilo that dug into a giant limestone peninsula, creating an impressive labyrinth of caves. The peninsula is known as the Marble Cathedral and can be reached by boat, during a guided tour.

The Swirls and Waves of Antelope Canyon

Gaze for too long at these rock formations, and you begin to drift off and forget whether you’re looking at a geological phenomenon or a vast, abstract oil painting. The swirls seem to envelop you, and in Antelope Canyon they actually do. Let’s take a ramble down this most gorgeous of gorges and lose ourselves in the wonderful play of light and patterns that captivate its many visitors each year. Here lies one of the planet’s greatest natural art galleries.
Antelope Canyon lies on Navajo land in the American southwest, nestled hidden in the Arizona landscape. One of the world’s true natural wonders, it is a place of splendid serenity, the sort of spot where people find themselves talking in hushed whispers without quite knowing why. As a slot canyon, it has been formed over thousands of years by the gradual wear of water rushing through rock.
Slot canyons are exceptionally narrow, far deeper than they are wide, and Antelope Canyon’s fantastic whorls and contours can be up to 150 feet tall, while being observable only by very small groups shuffling along the sandy floor. The canyon was formed by the erosion of Navajo sandstone, chiefly due to flash floods that still occur here, making this very much artwork still in progress.
Rainwater, particularly in the monsoon season, runs into a large basin overlooking the slot canyon, picking up speed and sand as it runs into the narrow passageways. Grain by grain, the corridors are deepened and the edges smoothed to form the exquisite shapes and graceful curves in the rock. Wind too has played a part in eroding and sanding this majestic canyon.
he geological rock sculpting here is split into two distinct areas. The Navajo people fittingly call Upper Antelope Canyon Tse’ bighanilini, which means “the place where water runs through rocks”. Lower Antelope Canyon, known to the Navajo as Hasdestwazi, or “spiral rock arches”, is less visited, as it is a longer and tougher hike and must be climbed into via metal stairways.
Here we see the view from inside Lower Antelope Canyon, looking out with a chink of the sky visible at the top of the frame. The characteristic layering of sandstone is clearly discernible, the layers of sand having built up as a result of sedimentation from water, or from air as in deserts. Scientific explanation assuredly has its place here, and yet these visual delights fit easily into the domain of art.
The magical gateway into Upper Antelope Canyon – indeed its entire length – is at ground level, which is one reason why it is the more visited of the two carved geological marvels. The other features that explain its greater popularity are the occasional shafts of sunlight that shine down through openings in the top of the canyon; these are more common in the Upper Canyon.
The beams of light are typically seen in the summer months because the sun has to be high in the sky for the angle of its rays to be just right. The phenomenon does not happen so often in the winter, and during this season the colours are slightly more muted, though no less magnificent, as in the photo shown below.
The summer months themselves offer two different types of lighting, according to the time at which they are witnessed. The play of light is a dazzling phenomenon, seen below catching and reflecting off the edges of the canyon. The way the light constantly changes seems to emulate the continual evolution of the rock faces.
Sometimes the pillars of light from overhead appear to evoke some kind of spiritual episode, like the stereotypical scene of a god speaking from on high. It comes as little surprise that to the Navajo people, the canyon has always been a place of reverence.
There is a strong sense that this is some kind of sacred space, a womb-like sanctum perhaps, and to the older Navajos entering such a place would surely have been like entering a cathedral. They would likely have left feeling enlightened by nature and in harmony with something greater than themselves. Being inside Antelope Canyon will always be something of a spiritual or transformative experience.
At times the rock forms seem to bear a resemblance to human or animal bodies in their shape and appearance, making the canyon all the more like a living, breathing entity. Here faces seem to come out of the wall, looking down quietly yet imposingly on those below.
Antelope Canyon really is a photographer’s dream; however it also presents difficult challenges due to the way the light enters the area, the large differences in light levels, and the wide exposure range caused by light reflecting off the steep canyon walls.
As mentioned, it is not just the light but the stratification of sandstone that makes Antelope Canyon such an enchanting experience for spectators. It really does call to mind the idea of an immense painter, working with light and rock instead of with oils. Each rock surface is a canvas for nature’s very own swirling compositions.
Yet despite the beauty and light of Antelope Canyon, this place also has darker, more dangerous aspect. This was all too apparent in 1997 when eleven tourists were killed in Lower Antelope Canyon by a flash flood that also washed away the then wooden ladders that may have provided a means of escape.
In the fatal 1997 event, the rain did not need to fall close to the canyon itself for the floods to come rushing down through its corridors. To trigger a flash flood here, all it needs is for a storm to deposit large quantities of water in the canyon basin, miles upstream.
The risk of sudden flooding is one reason why Antelope Canyon can only be visited through guided tours led by authorised guides. The canyon is also only accessible with a permit, and is a source of tourism trade for the Navajo on whose homeland it stands.
In the shot below, we see just how narrow the passages can get, particularly in the V-shaped Lower Canyon, which can be tricky underfoot at times. Sightseers can stretch out their arms and touch both sides in places. However amazing it may be, Antelope Canyon is not for the claustrophobic.
So we reach the end of our own tour through this wondrous temple of Mother Nature’s. Part natural phenomenon, part tranquil art gallery, part giant artwork in itself, Antelope Canyon will undoubtedly continue to leave visitors both speechless and restored, as it has done for thousands of years.

10 Geological Wonders you didn’t know

Chocolate Hills (Philippines)

Composed of around 1,268 perfectly cone-shaped hills of about the same size spread over an area of more than 50 square kilometres (20 sq mi), this highly unusual geological formation, called Chocolate Hills, is located in Bohol, Philippines. There are a number of hypotheses regarding the formation of the hills. These include simple limestone weathering, sub-oceanic volcanism, the uplift of the seafloor and a more recent theory which maintains that as an ancient active volcano self-destructed, it spewed huge blocks of stone which were then covered with limestone and later thrust forth from the ocean bed.

Wave Rock (Australia)

The Wave Rock is a natural rock formation located in western Australia. It derives its name from the fact that it is shaped like a tall breaking ocean wave. The total outcrop covers several hectares; the "wave" part of the rock is about 15 meters high and approximately 110 meters long. One aspect of Wave Rock rarely shown on photographs is the retaining wall about halfway up the rock. This follows the contours and allows rainwater to be collected in a dam. It was constructed in 1951 by the Public Works Department, and such walls are common on many similar rocks in the wheatbelt.

Hell Gate (Uzbekistan)

Called by locals The Door to Hell, this place in Uzbekistan is situated near the small town of Darvaz. When geologists were drilling for gas, 35 years ago, they suddenly found an underground cavern that was so big, all the drilling site with all the equipment and camps got deep deep under the ground. None dared to go down there because the cavern was filled with gas, so they ignited it so that no poisonous gas could come out of the hole, and since then, it has been burning. Nobody knows how many tons of excellent gas has been burned for all those years but it just seems to be infinite

Giants Causeway (Ireland)

An area of about 40,000 interlocking basalt columns, the Giants Causeway is a result of an ancient volcanic eruption. Located on the north-east coast of Northern Ireland, most of its columns are hexagonal, although there are also some with four, five, seven and eight sides. The tallest are about 12 meters (36 ft) high, and the solidified lava in the cliffs is 28 meters thick in places. In a 2005 poll of Radio Times readers, the causeway was named as the fourth greatest natural wonder in the United Kingdom.

Blue Lake Cave (Brazil)

Mato Grosso do Sul region in Brazil (and especially the quiet town of Bonito) boasts many marvelous underground lakes: Gruta do Lago Azul, Gruta do Mimoso, AquĆ”rio Natural. The world famous "Gruta do Lago Azul” (Blue Lake Cave) is a natural monument whose interior is formed by stalactites, stalagmites and a huge and wonderful blue lake. The beauty of the lake is something impressive. The Blue Lake Cave has a big variety of geological formation but impresses mainly for the deep blue colored water of its inside lake.

Eye of the Sahara (Mauritania)

This spectacular landform in Mauritania in the southwestern part of the Sahara desert is so huge with a diameter of 30 miles that it is visible from space. Called Richat Structure --or the Eye of the Sahara-- the The formation was originally thought to be caused by a meteorite impact but now geologists believe it is a product of uplift and erosion. The cause of its circular shape is still a mystery.

Crystal Cave of the Giants (Mexico)

Found deep inside a mine in southern Chihuahua Mexico, these crystals were formed in a natural cave totally enclosed in bedrock. A geode full of spectacular crystals as tall as pine trees, and in some cases greater in circumference, they are a translucent gold and silver in color and come in many incredible forms and shapes. The Crystal Cave of the Giants was discovered within the same limestone body that hosts the silver-zinc-lead ore bodies exploited by the mine and it was probably dissolved by the same hydrothermal fluids that deposited the metals with the gypsum being crystallized during the waning stages of mineralization.

Great Blue Hole (Belize)

Part of the Lighthouse Reef System, The Great Blue Hole lies approximately 60 miles off the mainland out of Belize City. A large, almost perfectly circular hole approximately one quarter of a mile (0.4 km) across, it’s one of the most astounding dive sites to be found anywhere on earth. Inside this hole, the water is 480 feet (145 m) deep and it is the depth of water which gives the deep blue color that causes such structures throughout the world to be known as "blue holes."

Antelope Canyon (Arizona - USA)

The most visited and photographed slot canyon in the American Southwest, the Antelope Canyon is located on Navajo land near Page, Arizona. It includes two separate, photogenic slot canyon sections, referred to individually as Upper Antelope Canyon --or “The Crack”-- and Lower Antelope Canyon --or “The Corkscrew.”

The Navajo name for Upper Antelope Canyon is Tse' bighanilini, which means "the place where water runs through rocks." Lower Antelope Canyon is Hasdestwazi, or "spiral rock arches." Both are located within the LeChee Chapter of the Navajo Nation.

The Wave (between Arizona and Utah - USA)

A red-rock stunner on the border of Arizona and Utah, The Wave is made of 190-million-year-old sand dunes that have turned to rock. This little-known formation is accessible only on foot via a three-mile hike and highly regulated.
