Sichuan, because it is located in the transition zone between the Qinghai-Tibet Plateau and the middle and lower reaches of the Yangtze River, has a large difference in landforms, and has always been a gathering place for various beautiful scenic spots, but at the same time there are also some horror zones that make people talk about discolored, such as the Black Bamboo Ditch known as "Bermuda of China", and the horror of the Black Bamboo Ditch is that many people have entered it and repeatedly disappeared mysteriously.
Heizhugou is located in Ebian Yi Autonomous County, Leshan City, Sichuan Province, is one of the most complete and primitive ecological communities in China, with a total area of 838 square kilometers, the altitude is relatively high, the highest point is about 4288 meters, the shortest place is also 1500 meters, the territory of water features, forest scenery, canyons are readily available, there are all kinds of rare species, but such a place that should be a paradise, but because of a series of mysterious disappearances of people and animals, and covered with a layer of horror and strange veil.
In the early days of the Liberation War, when Hu Zongnan, the Kuomintang army general who was most favored and valued by Chiang Kai-shek, was fleeing from the pursuit of the Eighth Route Army, he took advantage of his large number of people and excellent weapons, and entered the Heizhugou with more than 30 remnants of the troops, but the result was that no one ever walked out of the Heizhugou again. Then an American plane flew over Heizhugou and ended up with a plane that was destroyed and killed.
In 1955, two soldiers of a certain unit of china's People's Liberation Army cut a short way to deliver grain from Heizhugou to the troops, and eventually the grain and people mysteriously disappeared. Later, the troops dispatched two platoons of troops to search and rescue the vicinity, and only found weapons that the two men never left when they carried out their missions. In 1964, the forest survey team of the Southern Sichuan Forestry Bureau had to enter Heizhugou because of the needs of its work. The investigation team knew that Heizhugou was very dangerous, and they had somewhat heard about the mysterious disappearances that had occurred here, so they specially invited two local Yi hunters as guides, and also brought two hunting dogs. But when they arrived at the Black Bamboo Ditch Stone Gate Pass, only to see a white fog shrouded in it, there was no way to see the road, the guide had to let the two hounds go to explore the way, but soon the two hounds disappeared one after another, and the guide repeatedly shouted their names as usual, or did not see the trace of the hounds, nor did they have any response, only more and more thick white fog came to them, it seemed to engulf them, and the investigation team and the guide were frightened, and they rushed down the mountain, and did not dare to stay more.
In addition, it is worth mentioning that when the forest survey team of the Southern Sichuan Forestry Bureau went down the mountain, it was found that all eight compasses they brought into the Black Bamboo Ditch had failed. However, at first, when they were too panicked and nervous near Shimen Pass, they did not notice that the compass had failed, and it was not until the next day that they had to go back to the station at the bottom of the mountain and study the situation they had encountered on the topographic map, only to find that their route down the mountain deviated by 45 degrees from the malfunctioning compass. Because of this, they have been circling in Heizhugou for so long before returning to the station, if it were not for good luck, they would most likely be unable to walk out of Heizhugou again because of this 45-degree deviation. If it is a coincidence that a compass failure has a deviation, it is a bit strange that all the compasses carried by the eight team members have failed to deviate, and the values of the deviations are still the same.
In fact, these events are only recorded, and there are many mysterious disappearances and strange events that have not been recorded in Heizhugou. So why did so many mysterious disappearances and strange events occur in Heizhugou? In fact, among the local Yi people, there is a legend that has been passed down from generation to generation, the ancestors of the Yi people once lived in the most dangerous area of heizhugou, that is, in the gorge of Shimen Pass, and there is "ancestral training" that cannot enter, otherwise it will be disaster, so after people and animals enter it without authorization and make a sound, the ancestors will order the mountain gods to lower punishment and use layers of fog to sweep away the people and animals who broke into Shimen Pass. Of course, legends are legends because they have no factual basis, and we still have to analyze and solve puzzles from a scientific point of view.
With the occurrence of more and more mysterious and strange events in Heizhugou, many scientific expeditions and television stations want to enter one of them to uncover the mysterious and terrifying veil of Heizhugou. In the 90s of last century, a television station in Chengdu once organized an investigation team to enter it, but when it entered the edge of the black bamboo ditch, the investigation team was ready to shoot some materials, but found that the camera could not be opened, they thought at first that the battery was out of power, so they were ready to go back and make sufficient preparations to come again, but what they did not expect was that the camera that had just walked out of the black bamboo ditch suddenly got better, and the battery display was also full. And it is precisely because as soon as it enters the black bamboo ditch, the camera cannot be opened, and the investigation of Chengdu Television Station has not been carried out smoothly.
Although this investigation did not uncover the mysteries of Heizhugou, it made relevant experts realize that the mysterious disappearances and strange events of Heizhugou are likely to be related to the earth's abnormal magnetic field, so the Sichuan Provincial Land and Resources Department organized an expert group to conduct a more professional field investigation of Heizhugou. So are the various strange events in Heizhugou because there is an abnormal magnetic field here?
As soon as the experts arrived at the mouth of the black bamboo ditch, they used the meridian meter to measure the magnetic field and found that the magnetic field value here was 49300 nanat, what does this mean? The Earth's magnetic field is not immutable, it will change with the geographical latitude distribution, from the equator to the poles, the magnetic field is from low to high, generally between 20,000 to 30,000 nats and 50,000 to 60,000 nats. The Heizhugou and the Bermuda Triangle are all near 30 degrees north latitude, which translates to the magnetic field here should be around 50,000 nats, that is, the magnetic field of the trench mouth of the Heizhugou is within the normal range.
Since it is normal, is the speculation of the experts wrong? After all, the experts are professional, it is impossible to simply overturn the entire speculation because of one data, so they decided to go deeper into the black bamboo ditch and measure more magnetic field data as a comparison. When the experts walked about 2 kilometers to the south, the magnetic field value on the meridian tester began to change, and the magnetic field continued to increase.
It is reasonable to say that experts are measuring from north to south, that is, closer and closer to the equator, the magnetic field should be decreasing, and the increase indicates that the magnetic field is obviously abnormal. And when all kinds of strange events occur the most, there is a "ghost door pass" known as the stone gate close, the value of the meridian tester is more unexpected than the experts expected, but it is not the problem of the magnetic field increasing and decreasing, but the meridian tester, the professional instrument that measures the magnetic field, also directly fails, and the above value changes and does not have any research value. Then why does the stone gate of the black bamboo ditch have such an abnormal magnetic field?
Finally, experts found that the closer to the rock wall of the stone gate, the more the magnetic field changed dramatically. It turns out that the rocks on the rock walls are basalt formed by the solidification of magma from volcanic eruptions, which is a kind of magnetic rock, and not only that, but the iron content of this rock is also very high. Therefore, experts believe that it is the large distribution of basalt, a magnetic rock, that causes the magnetic field here to be abnormal, thus interfering with the normal direction of the compass, so that people who enter the black bamboo ditch cannot correctly identify the direction, and then mistakenly enter the black bamboo ditch into the undeveloped primitive area, and finally disappear in the dense forest, never to get out. As for the failed camera and meridian meter, it is also caused by the abnormal magnetic field here changing too violently.
That's all for this issue, and thank you for watching it, so stay tuned!
