"Double Vortex Tiankeng" in Luojiaba Town

There is a unique sinkhole "double vortex sinkhole" which belongs to the heyday sinkhole. What kind of story will there be? Hanzhong is closely related to the origin of Chinese culture, and traditional customs such as setting off river lanterns have lasted for thousands of years here. Setting off river lanterns is a traditional folk custom in China, which is usually held on the first and fifteenth day of the lunar calendar. On the Dragon Boat Festival, people hold a grand river lantern to mourn Qu Yuan and pray for his family. Due to the geographical location of the northern foot of Qinling Mountain and the southern foot of Bashan Mountain, it is also a breeding ground for many local religions. As an important school of early Taoism, the Five Thousand-meter Daoism was used for medical assistance under the name of "Five Doors of Rice". Legend has it that it was founded in Niuzi, more than 80 kilometers east of Hanzhong. According to Taoist records, the concept of five sons in the mountains is the origin of this Sect, and the unique landscape here also provides them with an excellent place to escape from the world.

Legend has it that there is a construction site on the rock wall of the double vortex sinkhole. According to local Taoist records, it is probably a Taoist temple with a wall on the mountain. Why are there ancient architectural sites? Luojiaba Town is located in the carbonate rock area of more than 70 square kilometers in Xixiang County, Hanzhong, with more than a dozen beaded sinkholes. It takes more than 20 kilometers to reach the double vortex sinkhole. Because of the unique double vortex sinkhole and rock wall? The mysterious ancient road view is the most typical tiankeng in Xixiang County. In addition, according to local villagers, "there are two sinkholes in the sinkhole, one is bottomless and the other is the common Yun Qi. But once someone speaks loudly in the pit, the fog in the sinkhole will disappear immediately. The clouds rising in Ran Ran, the mysterious ancient road view, the unique double helix structure, and all kinds of strange phenomena are hidden behind. Can the sinkholes with beaded distribution solve the same area? What is the relationship between the sinkholes?

The double vortex sinkhole is 25.8 kilometers away from Luojiaba Town. With the help of pickup trucks and agricultural tricycles, the expedition team needs to travel 45 kilometers to reach its destination. Everybody get off and walk through the no-man's land of 2 1 km. As the round trip takes nearly two days, the team needs to bring camping equipment and food supplies for at least three days. Unlike camping in the dark environment of Chanjiayan Tiankeng, this time I don't have to live in a cave. The tour guide said, "This no-man's land of 2 1 km was a different scene 50 years ago. Because most of the Yamazaki Mountains are mountain roads and dense forests, the traffic is extremely inconvenient. Since the 1970s, more than 200 villagers have moved out one after another, and only three families have been seen along the road, mainly beekeeping. Weeds on the roadside grow at a rate of one meter per year. Today, 50 years later, they are no longer found. The body is close to the common house mouse, and its forelimbs are like two shovels. Good at digging, living in caves during the day and coming out for food at night, mostly living in mountain basins and bushes. Mole's sense of smell is extremely sensitive. It can distinguish the smells of different foods in a three-dimensional home. No one has set foot here all the year round, which also nourishes a better living environment. Black bear, wild boar, leopard, wolf, takin and other large wild animals occasionally appear here.

The weather in Hanzhong is always so changeable. It didn't take long for it to rain heavily. A master Luo said: "This place is called Asarum Village, which is named after it is rich in Asarum. Asarum is a commonly used herb, which is listed as the top grade in Shennong Herbal Classic. It grows in high-altitude forests and wet soil. Asarum has antipyretic and analgesic effects. Chewing has a numb burning sensation. Asarum is named because of its fine root and pungent taste. The sudden disappearance of clouds in the fog dam, the ancient road landscape on the cliff and the unique double helix structure of the sinkhole are all strange phenomena that the scientific research team wants to solve this trip. What is the relationship between the sinkholes distributed in a beaded shape?

The expedition lowered the rope by about 30 meters and found a cave on the cliff halfway up the mountain. There is a kind of nematode that lives in darkness and caves. It doesn't need pigment to protect itself, so its whole body is transparent. Now it is crawling slowly along the spider silk, semi-green and translucent, but actually transparent. The internal organs look green. It must be that these nematodes often eat the color caused by a kind of green algae on the rock wall. There is a wild rhubarb outside, which uses roots as medicine to promote gastrointestinal secretion, so it is widely used in traditional Chinese medicine, and people don't feel very good about rhubarb. As the saying goes, "ginseng kills people without fault, rhubarb saves people in vain", and rhubarb often saves people more times.

Not far from the cave, there are artificial stone walls and caves. The tour guide told them: "The ancient Ba people used to live here. It is very likely that Cubans dug a cave to escape the war. White stalactites can be seen inside, but the roof of the cave collapsed and was dug artificially. As a result, it collapsed when I dug it to see if I could live. Three days ago, not far from Luojiaba town, the expedition saw a large tomb group with hanging coffins.

In ancient times, Ba people dug so many holes on this cliff in order to place coffins and preserve bodies. After he dug in, the crossbar was supported by the vertical wood below, and the coffin was placed on the wooden frame. Dig a deep hole and put a coffin, which should belong to the rich. It took him a lot of manpower, material resources and financial resources to dig such a deep cave to store the coffin. Hanzhong area belongs to the Cuban cultural area, while Luojiaba in Xixiang County belongs to the Western Regions in the middle period of Ba culture. The hanging coffins on the fairy cliff here reflect the ancient Ba culture. They are eager to be reborn after death, and gradually form such a burial culture of putting coffins on cliffs.

After an hour of rope descent, the expedition team finally reached the fog pit in the double vortex sinkhole connected by natural pine. The two sinkholes, large and small, form a north and a south, and the longest axes are 150 m and 1 10 m respectively. There are shafts in the sinkhole, with diameters of 30mm and 25mm, and the depth of the sinkhole is 20mm. There is an underground river in the sinkhole. Experts said: "The double vortex sinkhole is still under development. In the life evolution of the sinkhole, it belongs to the prime of life, just like the Shanjiayandong River sinkhole. The expedition has never found a route to the ancient road view. They tried to contact the only branch secretary of xixin village by satellite phone, but they never found a signal. The tour guide said, "According to the statue and incense burner that the village party secretary saw in it, it is not difficult to infer that someone must have practiced here. Then why are the Hanzhong Tiankeng Group distributed in a beaded shape along the east-west direction? Experts said: "The structural belt is the reason for the beaded distribution. In the late Permian, it was still a deep-water basin until the end of the late Triassic.

There are deep-sea sediments in this area. During the Indosinian movement, the plates continued to compress, which led to the widespread development of folds and faults. With the geological uplift, groundwater is continuously cut, and finally along the Qinling orogenic belt in the south of Hanzhong, it is located in the Yangtze block, and the structural junction zone at the junction forms the Hanzhong Tiankeng Group with east-west beaded distribution.

The next exciting time continues.
