Cave of Crystals - Chihuahua, Mexico


Planet earth indeed most extraordinary place as “Secret Marvels of the World” is a compendium of the world’s weirdest and most wonderful sights that really do have to be seen to be believed. You'd be forgiven for wondering if movie fiction had become fact while gazing upon the Cave of the Crystals in Mexico.  The Giant Crystal Cave is an amazing cave connected to the Naica Mine at a depth of 300 metres, in Naica, Chihuahua, Mexico. This remote part of northern Mexico, located is an hour to the south of Chihuahua, is famous for crystals, and paychecks at the local lead and silver mine, where almost everyone works, are meager enough to inspire a black market.
The cave was discovered by the brothers Eloy and Javier Delgado. These days’ scientists are working in the cave to conduct research on the crystals. Although the conditions are extremely difficult, but their efforts seem to be paying off. Investigators have discovered a new type of gypsum formation, collected ancient pollen in the crystals, and extracted the DNA of extremophiles trapped in the crystals to match them to their closest living relative.

Unfortunately, the crystal caves at the Naica mines are open to scientific investigation only. Even in this case, each visitor needs the proper equipment, as the temperature and humidity can easily overheat the human body. The cave contains staggeringly huge crystals as some of four metres thick. Researchers believe some of the crystals are 500,000 years old. The cave of crystal is extremely hot, with air temperatures reaching up to 58 °C with 90 to 99 % humidity. The main chamber contains some of largest natural selenite crystals. The largest crystal found in this case is 12 m in length, 4 m in diameter and 55 tons in weight.
The cave is relatively unexplored due to many reasons without proper protection; people can only endure about 10 minutes of exposure at a time. The underground magma lies about 2 to 3 miles below the cave, heated the ground water which was saturated with sulfide ions. Thus, cool oxygenated surface water contacted the mineral saturated heated water, but the two did not mix due to the difference in their densities. Therefore, the oxygen gradually diffused into the heated water and oxidized the sulfides into sulfates. Moreover, the hydrated sulfate gypsum crystallized at a particularly slow rate over the course of at least 500,000 years, forming the giant crystals found nowadays.

In 1910 miners unearthed a cavern beneath the Naica mine workings, the Cave of Swords, located at a depth of 120 metres, above the Cave of Crystals, and contain spectacular, smaller 1 to 3 ft. long crystals. It is speculated that at this level, transition temperatures may have fallen much more rapidly, leading to an end in the growth of the crystals. Giant Crystal Cave was discovered in April 2000 by miners excavating complex in Naica contains substantial deposits of silver, zinc and lead. The Cave of Crystals is a horseshoe-shaped cavity in limestone, covered with perfectly faceted crystalline blocks. Huge crystal beams jut out from both the blocks and the floor.
The caves are accessible nowadays because the mining company's pumping operations keep them clear of water. If the pumping were stopped, the caves would again be submerged in water. The crystals deteriorate in air, so the Naica Project is attempting to visually document the crystals before they deteriorate further. The cave was featured includes credence to the existence of further chambers, but further exploration would have required significant removal of the crystals. As the cave's accessibility is dependent on the mine's water pumps, when mineral exploitation is ended in the area it is expected the pumps will be shut off and the cavern's water level allowed to rise again.

The Wilderness of Bisti Badlands


The Bisti Badlands, which is also called Bisti/De-Na-Zin Wilderness, is a massive rolling landscape of phantasmagoric formations of earth and stone situated in northwestern New Mexico’s high desert lands. Bisti is resulting from the Navajo word “Bistahi” which means "among the adobe formations." De-Na-Zin takes its name from another Navajo word for "cranes." In this beautiful landscape here wind and water erosion over a long time have carved a imaginary world of bizarre rock formations and hoodoos in the form of pinnacles, spires, mushrooms and other rare forms that have fascinated names such as "Cracked Eggs", “Bisti Wings” and "Rock Garden".

This is untouched area so far and very least visited and mostly unknown was once an ancient riverine delta on the shores of an ancient sea, somewhere 70 million years ago. As the time passes the water gradually receded, lush foliage grew along the numerous riverbanks and several prehistoric animals wandered the area. Therefore, when the water disappeared completely, it left behind layers of jumbled sandstone, shale, mudstone, and coal. However, abundance of the coal burned away in ancient fires that lasted centuries. Moreover, erosion then formed the characteristic features of the contemporary landscape of the Bisti Wilderness. Furthermore 6,000 years ago, when the last ice age retreated, the waters of the melting glaciers assisted uncover fossils and petrified wood, as well as eroding the rock into the hoodoos now observable. Mostly three kinds of formations are bare in Bisti Wilderness area — the Ojo Alamo Formation, which has left naked the thick deposit of volcanic ash from an ancient eruption, and Fruitland formation and the Kirtland Shale. Here are recreational activities in the Bisti/De-Na-Zin Wilderness includes hiking, camping, wildlife viewing, photography, and horseback riding. Make sure, campfires are forbidden in the Wilderness.

The Ojo Alamo Formation extents the Mesozoic/Cenozoic boundary, and typically contains dinosaur remnants. Thus, the Fruitland Formation comprises layers of sandstone, coal and shale was laid down when the surroundings were marshy, humid and warm, with meagre drainage. The Fruitland Formation is found mainly on the western side of the Wilderness. However, the Kirtland Shale is the product of alluvial muds and overbank sand deposits from the numerous channels draining the coastal plain in the late Cretaceous period. Though, it overlies the Fruitland Formation, and is exposed on the eastern side of the badlands. Several of the gray hoodoos in the wilderness are made up of this formation. The exclusive egg-shaped formation, in the “egg factory” area, is also the result of erosion. Consequently, the cracks are the result of differential weathering conditions, whereas the speckled appearance due to mineral deposits in the stream that cut through the sedimentary rock. The Bisti Badlands is an amazingly scenic and colorful expanse of undulating mounds and unusual eroded rocks covering 45,000 acres, hidden away in the high desert even less publicized. The badlands are administered by the BLM (Bureau of Land Management), are free to enter, and are known officially, but less evocatively as the Bisti Wilderness Area.

Enchanted Mesa, A Sandstone Butte in New Mexico



Enchanted Mesa or Mesa Encantada is a sandstone butte in Cibola County, New Mexico, United States, about 2.5 miles northeast of the pueblo of Acoma. It was home of the Acoma people until a massive landslide and severe storm completely demolished the only approach.  There are no longer any ruins on the flat top. The butte is 430 feet high, 1,250 feet long and only 400 feet wide, at its widest. The elevation at the top is 6,643 feet. It is believed that massive cliffs are formed by the Zuni Sandstone and the butte is topped by the Dakota Sandstone. 

In 1892 The Charles F. Lumins visited Acoma and express the story of Acoma People life style on Enchanted Mesa.  The access from southern side to top with a large piece of butte had spalled off and formed a ramp called stone ladder up to the top. So, there main source was their fields, springs, and water source were in the valley.  Therefore, once the summer season start, the entire village descends into the valley to tend the crops.  So, once an unfortunate day, a severe thunderstone washed away the stone ladder leaving only sheer rock faces all the way around the butte. Only one young boy and three old women did not leave in the village, which couldn’t get down nor could anyone else get back to the village. 

A giant thunderbird swooped down and scooped up the four and carried them to the valley floor. The Acoma people abandoned Enchanted Mesa and moved to White Rock Mesa, now called Acoma. In 1897, Professor Williams Libbey from Princeton University climbed Enchanted Mesa, where he spent two to three hours in exploring, however he didn’t find anything ruins or artifacts. 

Moreover another archaeologist Frederick Webb Hodge didn’t believe Libbey findings, and he went on expedition in 1897 and found evidence of occupation, arrow points, stone tools, beads and pottery fragments lodged in crevices. He said, main ruins had been washed over the edge by many centuries due to massive thunderstorms. In 1974, an Acoma police officer claimed, that he had seen a UFO over Enchanted Mesa, which was later confirmed by other police officers, a red light, fast than any aircraft. So, a helicopter was sent to top of Enchanted Mesa to find the evidence of UFO, however no direct evidence was found.

Ancient Acoma Pueblo Sky City

Tiny settlement has been home to the same tribe for 800 years still doesn't have running water or electricity and is reached by a staircase cut out of rock nestled on top of a large cliff in New Mexico is a sleepy commune that is believed to be the oldest continuously inhabited settlement in North America. It is believed that Acoma Pueblo in Valencia County has been occupied by the Acoma people for more than 800 years, since 1150AD - however nowadays it only has 50 full-time inhabitants even they don’t have any running water, electricity or sewage system. In the 1950s part of the rock-face was blown up and a road was constructed to the top. But before that the only way to visit the site via 360 feet above the desert was up a near-vertical staircase carved into the golden rock-face.

Therefore, these days, most visitors use the road, but the staircase is still an option for those who are courageous enough. It is conventional, given its dizzying heights, that the camp is also recognized as Sky City. Several centuries ago, in 1540 Spanish explorer Francisco Vazquez de Coronad was one of the first European visitors to the ancient settlement.  Acoma Pueblo was 'one of the strongest places ever seen, because the city was built on a high rock. The ascent was so difficult that we repented climbing to the top'. Thus, approximately 60 years after this, raids started in the area, led by colonial governor Juan de Oñate. Moreover in a bid to defend their sandstone dwelling, the Acoma Pueblo villagers made the first move and were said to have killed a number of men, including Oñate's nephew.

So, it turned out to be a terrible idea, as two months later the Spaniards pursued revenge, killing 600 inhabitants and enslaving 500 others.  The settlement's population rapidly dropped from 2,000 to just 250, with survivors starts in on the slow process of reconstructing their home. Although, Spanish control was still felt in Acoma Pueblo, though, with villagers enforced to pay taxes on cotton, crops and labour. Furthermore, Catholicism was initiated with the arrival of missionaries and somewhere in between 1629 and 1640 a church was erected in the camp. Building this was no easy feat, as 20,000 tons of stone and earth and 30 foot beams had to be lugged up the steep mountain, because not everyone was pleased with these new changes.

The Pueblo Revolt took place in 1680, with more than 17,000 inhabitants rising up against colonists, wiping out all the Spanish camps in the area. Further invasions occurred during the centuries that followed, mostly from the Apache, Comanche, and Ute tribes and the establishment of railroads in the 1880s saw a stream of missionaries and schools trying to influence the Acoma Pueblo dwellers. Lastly the villagers gave way to a more modern lifestyle, and by 1920 a lot of of the children were sent away to boarding schools for education. Hence, now there are around 300 earthen buildings still unharmed, but very few enduring inhabitants due to the lack of electricity, sewage disposal and running water. The greatest things about Acoma are the people, who consider themselves to be a peaceful and spiritual group that will merged into the world.
