Ice back

Bingbingbei is located in the northwest of Shibanyan Township, Linxian County, Anyang City, Henan Province. The ice area is about 600 square meters. Every year from winter to spring, when the grass comes back to life (in March), it begins to freeze here for as long as five months. After the Mid Autumn Festival in August, when it seems cool, the ice here begins to melt. When the ice age was at its peak, it happened to be the midsummer season. On a rainy day, when I stepped into this piece of treasure, the cold air immediately hit me.

Ice back

Ice back is located in the northwest of Shibanyan Town, Linzhou City, Henan Province, where the water temperature is warm in winter and the water is cold and frozen in midsummer. The ice area is about 6 square meters. Every year from winter to spring, when the grass comes back to life (in March), it begins to freeze here for as long as five months. After the Mid Autumn Festival in August, when it seems cool, the ice here begins to melt. When the ice age is at its peak, it happens to be the midsummer season. On a rainy day, when you step into this treasure land, the cold air immediately hits people and the air is biting to the bone. However, in the middle of winter, there was a trickle of water flowing out from the stone crevices. The hot air was transpiration, the spring water was mild, and the water and grass along the stream were luxuriant, which caused the peach trees nearby to sprout and bloom in advance. It makes people feel the reversal of seasons. It is a summer resort called "reversal of winter and summer" by the ancients. Because the cave is on the shady slope of the mountain, the local people used to call it "back", so it is called bingbingbei.

Myths and legends

There is also a magic story about bingbei: in ancient times, it was a deep pool. The pond water is used for watering and drinking. One summer, an evil Dragon flew in. Suddenly, the sand and rocks flew away. The fire burst into the sky, the vegetation withered, and the pool water dried up. People have no choice but to ask the dragon to avoid disaster. Where is the Dragon willing to respond! People built temples and prayed, but the Dragon did not follow. At that time, tie guaili, one of the eight immortals, happened to pass by. When he saw the evil dragon, he couldn't bear it. So he poked his stick to the bottom of the sea and ordered the Dragon King to release the water. Then he threw a piece of ice from the treasure gourd and covered the pool tightly, pressing the dragon to the bottom of the pool. So, there is this spectacle.

Geological phenomena

A peculiar geological phenomenon ice back

There is a peculiar geological phenomenon in the deep mountain more than 10 kilometers away from Shibanyan Township, Linzhou, Henan Province. Every summer, large pieces of ice grow in several shallow caves in the shade. The hotter the weather is, the bigger and harder the ice grows. In autumn, as the weather gets colder, the ice begins to melt. In winter, the ice turns into warm water, which local people regard as a good example A peculiar geological phenomenon is called ice back.

Cause of formation

More than 10 years later, the geophysical exploration team of Henan Bureau of Geology and mineral resources carried out electrical exploration and geological interpretation

This area is located in the southern section of Taihang Mountain, 1500 meters above sea level, with steep cliff, dangerous mountains, overlapping jungle, and slate Grand Canyon in the East. Ice back is located in the valley at the foot of the mountain. There are many cold air coming out of the surface from stone crevices or small caves. Most of the cold air is distributed in a belt parallel to the east-west direction, and the length of the belt ranges from several meters to several hundred meters. It is found that two ice cones grow outward in the crevices or caves from June to August every summer, or attach to the stone wall or grow in the crevices. After the beginning of autumn, the ice gradually disappears, but the ice is cold I'm as angry as ever. In winter, fog comes out from the cracks in the stone, and the snowflakes melt when they fall. There is a clear spring flowing out about 100 meters to the East, which is not affected by rainy season and dry season. There is also a clear spring flowing out in the north, which has a great influence on the flow in rainy season and dry season.

There are no shrubs or big trees growing near the air-conditioning or freezing point, but only small grasses. Only two kinds of nameless grasses grow vigorously, but disappear a few meters away from the air-conditioning zone. It can be seen that these two kinds of flowers have low temperature specificity.

In terms of geological structure, the area is located in the center of North China platform, Shanxi uplift and Taihang arch. There is a slate anticline in the East, and the ice back is located in the West Wing of the anticline. Due to the subduction and compression of the Pacific plate, the Taihang uplift belt was formed, and the neotectonic movement was the main body of the area. According to the observation of the State Seismological Bureau, Taihang mountain rises by 3 mm every year, and senseless earthquakes occur several times a day, which shows that the neotectonic movement in this area is very active.

There is no cement between the collapsed rocks near the ice back, which proves that it is the product of modern tectonic movement. The area is located in the west side of the anticline axis, forming a tensile fault Valley in geomorphology, with small vertical short distance. A large fault passes through the back of the ice. The horizontal displacement of the rocks on both sides is 300-500m. The fracture width below the back of the ice is about 300-400M. The low temperature points are located above and near the fracture zone.

According to the geological and geophysical investigation, the refrigeration mechanism is that the high density gas in the deep crust rises and absorbs heat after the surface density decreases. In line with the principle of refrigerator, it is a huge natural cooling source. The cooling mechanism is caused by six special geological conditions

The first is the condition of gas compression: the Pacific plate moves westward and compresses the North China plate, forming a compressional subduction zone on the east side of Taihang. The southern part of the belt is the Tangyin graben, with a basement depth of about 3000-4000 meters. The Western uplift is the Taihang Mountains, with an altitude of 1300-1800 meters. The Taihang orogenic belt is the result of Himalayan movement. The Tangyin graben continues to decline, the Taihang mountain rises every year, and the Linxian generation of small earthquakes continue. This shows that the Quaternary orogeny is still in progress. There must be a huge squeezing force at the foot of Taihang Mountain, forcing the gas deep in the crust to compress and rise.

The second is the gas conduction condition: the ice back is located above the large fault. Due to the uplift of the crust, the thick and brittle quartzite of the ancient boundary formed a tensile fault with a large depth, forming a good gas conducting system.

Third, gas storage conditions: the Guojiazhuang fault extends westward to the west of chefogou, enters into the lower Paleozoic strata and then is concealed. After 6 km westward, it reappears near Yangjiaogou, Shanxi Province, and the lower Cambrian shale has formed a better closed cap rock.

The fourth is the direction of gas conduction: because the strata in the West Wing of the slate anticline incline to the west, the rocks near the ice back incline to the West or northwest, with an inclination of 5-15 degrees. Therefore, the gas conduction is from west to East.

The fifth is the special geographical location of the ice back: it is located near the junction of quartzite and shale above the fault, which is the outlet of high-pressure gas rising along the fault in the deep crust.

The sixth is the influence of atmospheric pressure: ice appears from June to August and disappears in other seasons, which is probably related to atmospheric pressure. In summer, the air is hot, the air pressure is low, the underground updraft speed is high, and the cooling effect is strong; in other seasons, the air pressure is high, the underground airflow speed is slow, and the cooling effect is weak.

According to the expert's suggestion, the local government invested millions of yuan to dig a deep hole from here, and a miracle happened. There was a strong wind blowing out in the hole, and the cold wind was piercing in the whole hole. As long as there was a drop of water, it would immediately form ice, that is, there was a bucket of water, which would be frozen in one night, and sometimes the bucket would be cracked. If you use some molds, it will freeze into vivid shapes. After renovation and development, it has become a Geopark type tourist scenic spot with great scientific and appreciation value, which is the iceback tourist scenic spot.

Traffic information

There is a shuttle bus to Shibanyan from 9:30 to 16:00 every day at Linzhou bus station. After arriving at Shibanyan, transfer to the local traffic to the scenic spot.

Scenic landscape

There are cold ice, high mountains, Junfeng, ancient water, secluded caves, strange rocks, stone flowers, exotic grasses and precious trees on the ice back. It is a natural Geopark. It is a wonder in the world. The whole district is divided into eight districts

 

Ice back zone 1: there are four or five large and small ice caves, covering an area of more than 6000 square meters. There are ice caves, blowing holes, fox cave, bottomless cave, etc. the largest ice cave is 100 meters deep. There are ice flowers, icicles, ice cubes, ice cones, etc. in the cave. The temperature has been kept at about minus 78 degrees Celsius. With the increase of temperature outside the cave, the ice inside the cave is getting colder and colder, and the ice layer is getting colder and colder Thick. But in the cold winter, it's steaming, smog rolling, grass turning green around the cave, and the temperature is pleasant. There is a poem as proof: "in midsummer, the heat matches the winter, the flowers reflect the ancient ice.". When it's winter, it's warm, and the scenery here is like spring. "

 

Leisure locust forest area: in the top left of bingbingbei area 1, there is a dense locust forest, and a path winding along it becomes a secluded path for mountain leisure. In spring, green leaves and white flowers are fresh and fragrant, birds are singing together, and swarms of bees are singing and dancing, so you can enjoy the wonderful scene; in summer, trees are shady, covering the sky and avoiding the sun. In autumn, Robinia pseudoacacia fruits, strings of Sophora beans hanging all over the branches, rustling sound in a different scene.

 

Bingbingbei zone 2: in the valley on the right side is bingbingbei zone 2, covering an area of 3000 square meters. Surrounded by pine forest, cool wind bursts out in the stone crevices, which is attractive and refreshing. From time to time, there are snow blocks left in winter in the stone crevices, giving people the feeling of meeting treasure.

 

Magnificent stone flower area: above the second area of bingbingbei is a huge stone area of different sizes. There are many stones arranged disorderly in the area, some like elephants, some like ancient pagodas, some like giants. The largest stones are as big as dozens of houses, which were formed by the ancient earthquake. The stones, large or small, are white on them, or
