What unsolved mysteries exist in Mexico’s “Golden City”?

In the past, there was a popular legend in Mexico: The Arazares lived in a castle connected by seven cities, where life was rich and gold was everywhere. People called these seven cities "golden cities." ".

This legend stimulated the desire of many adventurers, and they flocked here, hoping to find this ancient castle. The explorer Francisco is one of them.

In 1504, Francisco hired several strong and adventurous men to form an expedition team and headed to Mexico to start looking for the legendary "Golden Ancient City".

The work of finding ancient cities is difficult and painful. They ate and slept in the open and traveled across mountains and rivers. Several years later, they still found nothing. Later, the expedition had to disband because of Francisco's bankruptcy.

In the hundreds of years since then, people have never stopped searching and verifying this legendary monument.

Just over 300 years after Francisco’s failed expedition, in 1888, this ancient castle was accidentally discovered by two shepherd boys. From then on, the golden city of the Arasara people began to become one of the wonders of the world, and it led to many mysteries that were difficult to solve.

The morning of this day was sunny and windy. It is already the depth of winter, and it is rare to have such sunny weather.

Luo Fei and Biter held the shepherd whip in their mouths and freed their hands to fasten their clothes while driving the sheep to graze in a daze. Luo Fei and Bit were two clever boys of the same age. Since they had just woken up and their eyes had not been fully opened, they looked like two little drunkards, following the sheep with one foot high and one foot low. After walking for a while, the older Luo Fei looked up and looked around. Suddenly he woke up. To his confusion, the sheep reached a hillside in Mesa, Colorado, and below was a desolate canyon. Luo Fei drank the sheep.

On the sunny side of the hillside, the pasture is only slightly withered and yellow, and the sheep are munching here.

Luo Fei and Bit discussed going to find some wild bird eggs or wild fruits nearby to satisfy their hunger.

Suddenly, dark clouds covered the sun, and a strong wind roared across the mountains. The sheep suddenly became panicked and fled in all directions. Bit was immediately in a hurry. Just as he stopped the sheep, the other sheep ran away again. He was so anxious that he almost burst into tears. When Luo Fei, who was picking wild fruits, rushed back, most of the sheep had dispersed. The two men drove the sheep back while looking for the lost sheep.

A little further home, eight sheep were missing, so the two went back to look for them.

At this time, large tracts of snowflakes were already floating in the sky.

Luo Fei wondered if those sheep had fallen into the canyon? The two people lay on the edge of the cliff and looked into the canyon. There were sheep bleating vaguely at the bottom of the canyon. They felt happy, so through the falling snowflakes, they vaguely saw some buildings at the bottom of the canyon.

Why are there buildings in the canyon? The two shepherd boys followed a small rope marsh on the cliff to the bottom of the valley, and saw an ancient castle appearing in front of them.

This is the home built by the Arasara people, but it is now empty.

As soon as the news spread, it attracted many visitors.

Judging from the scale of the entire castle, it can accommodate about 5,000 people. It is really puzzling that such a barren place can support so many people.

The architecture of the castle left a deep impression on people. Most of the houses of the Arasara people are civil structures. The most spectacular house has three floors, covers an area of ??3 acres, and has 800 rooms. The house is made of tens of thousands of flat stones, the beams are made of more than 20,000 pine trunks, and the stones and trees were transported from 35 miles away. However, ancient scientists were surprised to find that when these Arasara people transported these stones and materials, they did not use animal power or wheeled transportation tools. This is really puzzling. The masons' hands were also very dexterous. Each stone was laid neatly, and the stone gaps were filled with mortar and gravel. The whole building was like a natural scenery. Moreover, the acoustics in the room are also very good. Someone whispering here can be heard clearly on the other side of the partition wall. A sneeze in the room is like thunder and lightning.

The canyon here is a barren land, but the Arasara people created an incredible culture here, which has won the admiration of many historians. How on earth did they build such a prosperous castle in this desolate place and support such a large population? What is even more puzzling is why they suddenly abandoned their beautiful homeland and moved to other places in the early 13th century, and then disappeared from sight. What a mystery after another!

People can’t find a satisfactory answer yet, but the castle here has become a wonder. Encountering a UFO

One day in February 1959, the weather was clear, and Pennsylvania Civil Aviation Company Flight 713 was flying to Ohio. It was too easy for Captain Killian to fly the plane in such weather conditions.

Suddenly, Killian saw a UFO flying straight towards Flight 713.

It was taken aback.

Soon, the UFO was suspended at a certain distance from the plane, as if waiting for an opportunity and preparing to take action.

Suddenly, the UFO disappeared.

Its speed was so fast that I didn't even know how it disappeared.

Killian breathed a sigh of relief.

Unexpectedly, the UFO appeared again after a while, and Killian's nerves became tense again. He thought:

"Is it true that the 'flying saucer' has a base there?" , Did you go back to report the situation just now?"

Killian took a closer look at the UFO. It was much larger than his own plane, and its whole body was shining with a strong white light.

The "flying saucer" was suspended in front of the plane, as if it was waiting for something, and seemed to eat the plane again like a beast.

Killian thought:

"If the 'flying saucer' doesn't get out of the way, his plane will suffer."

Killian immediately stabilized Due to my own emotions, I decided to change direction and avoid the "flying saucer".

At this moment, the "flying saucer" suddenly rose and disappeared at an extremely fast speed.

After arriving at the destination, Killian reported the situation to the airline. What made him very strange was that the pilots of the other two planes of the airline also saw the "flying saucer". The situation they encountered was similar to that of the flying saucer. Pretty much what he encountered.

Do UFOs really want to hijack planes? It's really puzzling. The sinking city

Mexico City began to sink hundreds of years ago, sinking one foot every year and has not stopped. The local government is planning to pay a price of 14.6 million pounds to end the city's continued sinking. Shen.

The city’s subsidence not only affects the houses, but also makes the streets rugged, with many main streets taking on a wavy shape. The most special thing is that there is a new hotel in the city that was recently completed. Visitors must climb through a hill-shaped corridor before entering their rooms.

The reason why Mexico City continues to sink is that the city's strata were originally a large, semi-dry lake, with only a thin layer of soil covering the lake's surface - the ground of the city. Because the loose soil on the lake could not support the city's pressure, chronic subsidence occurred.

It is said that the top layer of the muddy loose soil is composed of water and dead ash ejected from the volcanic crater, with water accounting for 93%. Below it is layers of soil, gravel and water mixture.

Of course, anyone can imagine that it is difficult for a building to remain in its original shape for a long time without tilting on a gruel-like ground. The ancient Aztecs were very far-sighted in this regard. They thought of using wooden stilts to support buildings and reduce their tilt. After the Spanish occupied the city, they improved and utilized the above construction methods and built many four-story buildings, which were relatively stable. Modern engineers have discovered that if they drive Chinese oak hundreds of feet deep into the ground and lay up the original foundation one after another, it is said that there will be no problem in building a taller building. Because of this, the foundation of the building was laid on the solid soil at the bottom of the lake.

Developing the above principles, famous local engineers successfully built a standing international lottery building in the city. This design is like floating the house like a boat on the middle of a semi-dry soft lake. The advantage of this new construction method is that if the house once tilts, an electric pump can be used to right it again. But this kind of building also has shortcomings. If someone builds another building not far from it, it will be in danger of overturning at any time. Only by deepening its original foundation can it be stabilized.

Although this newly invented construction method is available, it still cannot solve its hidden dangers. Although the problem of preventing houses from tilting has been solved, the city's continued sinking trend has not ended. Judging from the sinking rate of one foot per year, if no measures are taken to stop it, the city will inevitably be destroyed. In order to stop the city's continued sinking, the local government has ordered all wells to be closed, and no water is allowed to be drawn from the wells. All water supplies must be replaced by mountain water. The reason why the government wants to implement this measure is that the city's population has increased significantly in recent years, and there are more and more wells. In order to prevent the semi-dry slurry mud layer underground from shrinking naturally once the underground water is drained, and the ground will follow. sink.

Many experts are now trying to find ways and take emergency measures to save the fate of Mexico City. But what the outcome will be, only time will tell.
