Heizhugou expedition

The ninth day of entering Heizhugou.

It was sunny overhead and the exploration team stopped to have a rest. Shen Rou went to the stream to fetch water with a kettle. The stream in the mountains is very sweet. In contrast, the deep mountain springs advocated by merchants outside the mountain are simply fakes. The work of the exploration team has almost been completed. We will take a short rest along the current south to wucun, replenish some food and medicine, and continue south to xihe town, where there is a bus to the county seat, and then we can go back to Chengdu.

After trudging on the mountain road for nine days, Shen Rou now misses her bed in Chengdu very much.

"Sister Shen, it's raining." The furry monkey yelled at her. The hairy monkey is tall and thin, and his surname is Hou. Shen rou has always had a question, it should be called pencil necked. "I won't be fooled." Shen soft response.

The hairy monkey is a clown in the team. He likes joking at ordinary times, especially with Shen Rou. But it is also a decompression agent in the exploration journey where dangerous nerves may be nervous at any time.

As soon as Shen Ruan's words were finished, there was a scratching voice overhead. She knew it was the sound of raindrops hitting the leaves. The weather in the mountains is also very strange. In the blink of an eye, it changed from sunny to heavy rain. Shen Rou returned to the team, dug out his raincoat and put it on.

The sound of raindrops hitting the leaves is getting louder and louder, such as firecrackers and drums. The sun quickly receded, the dark clouds pressed down, and a thick layer of rain and fog formed in the forest. It was dark in front of me, and only the rumbling sound was heard in my ears.

"Team Chen, I think there is something wrong with the voice." The hairy monkey said to Team Chen. Chen Du, the leader of this exploration team, has conducted many field explorations and has rich experience.

"Everybody take good things and don't leave the team." Chen Du said.

As the rumble grew louder and louder, everyone understood that it was the sound of water, rushing from the front. The water vapor brought by the current rushed over, and in an instant, a few meters high water waves came to my face, like a beast with a big mouth, trying to swallow the expedition into its mouth.

Shen Rou puts on her backpack and fastens the front belt. All the medicines are in it, and the heavier things are in the monkey's place. In case everyone gets hurt, these drugs are life-saving ... this is Shen Rou's last consciousness before being knocked down by the water wave.

It hurts all over. It's like falling apart and being put together again. I can raise my hands, but I can't raise my arms as if I don't belong to one person. Shen Rou is lying on a rock, and there is a stream flowing slowly under her feet. It's getting dark, but this place where he is is by no means the place where he just met a flash flood.

I still have my backpack. If I remember correctly, I still have half a pack of compressed biscuits left in the morning. Fortunately, I threw them into my bag. Only myself, others are gone, I don't know where they were washed away by the flash flood, whether they were together or scattered. Shen Rou shouted a few times, only to hear his own echo, echoing over and over again in the mountains.

No one answered.

Before the flash floods broke out, I ate compressed biscuits for several days, and I felt sick when I saw them. Now I have half a bag of life-saving food. I don't know knowledge point one

Heizhugou: Located in Ebian County, Sichuan Province, it is located in the transition zone from Sichuan Basin to Western Sichuan Plateau, with an area of about 1.80 square kilometers. The geological structure is complex and the landform types are diverse. Under the influence of strong neotectonic movement and lithology, it was cut by the cold action of seven glaciers and the erosion of flowing water, forming seven unique alpine geomorphological structures and landscape characteristics.

Heizhugou Valley has high terrain, numerous peaks, primitive ecology, rare species and unique and magical landscape. The local township is called "Shi Huo", that is, the Valley of Death. Many people and animals have disappeared. The local Yi and Han people call Heizhugou the "Devil's Delta" in the southern forest region, and it was once widely called "Bermuda, China" by public opinion at home and abroad. After deliberation by China Forest Landscape Evaluation Committee, Heizhugou was approved as a national forest park by the State Forestry Administration on February 22nd, 2000.

Knowledge point 2

Flash flood: refers to the skyrocketing flood in the ravine. Sudden mountain torrents, concentrated water flow, strong scouring destructive power. Sediment and even stones are entrained in the water flow, which often causes local floods, which are generally divided into rainstorm flash floods, snowmelt flash floods and glacier flash floods. Mountain torrents and their induced mudslides and landslides often cause casualties, destroy houses, fields, roads and bridges, and may even cause dams and ponds to burst.

When can I see the expedition? I wonder if I can see them. Even if I am not eaten by wild animals, I am afraid that I will starve to death first. Shen soft absently wondering.

To the south, there is a village called Yiwu, which can be reached in four or five days if the hiking trip is fast. Shen Rou once again confirmed the contents of the bag, besides medicine, there is also a flashlight, his own card machine and compass. The raincoat was covered with black mud and the front was cut with a long hole. Shen Rou took it off, washed it by the stream, folded it and put it in her bag. She ate two compressed biscuits, carefully put the rest back in her bag, and took a few sips by the stream.

Knowing about the telegram, the leaves rustled and Shen Rou became alert. There will be no wind. Is it human or animal? The information I saw before Heizhugou flashed in my mind. Since 1950s, there have been many human and animal disappearances. The missing persons include rangers of forestry departments, who are professionals. However, the expedition stayed in Heizhugou for nine days, encountered several sudden heavy rains and fog, and even saw pandas, but nothing strange happened.

The stream is full of pebbles washed away by the current. Shen rou picked up a palm-sized piece in one hand and stared at the direction in which the branches shook.

With a growl, I can't hear what animal it is. At this time, Shen Rou wished that there was a lovely giant panda behind the branch. The branches are pulled down by the objects below, and the trunk is bent into a big arc. Although the trunk is not very thick, the weight of that object should be quite large. Bang, the branch bounced back and a black thing jumped up.

When the pebbles in his hand hit him, Shen Rou turned and ran. He didn't see what animal it was, and his intuition told him to run as fast as possible! Don't take your backpack, it will only slow down your escape. If you can come back and get it.

"hey!"

Is it a human voice? Shen Rou climbed a tree and stopped. Is it a hairy monkey? In this case, you can't always play tricks on yourself. Looking back, my god, I'm not from the expedition, but I'm a person, dressed in black, with a mixed face and a big black backpack. At first glance, I look like a black bear.

Wei Zhou was also separated from his companions by flash floods. He finally got up from the steep slope below and breathed a long sigh of relief. It was the sound of a suspected animal growling that Shen Rou had just heard. Unexpectedly, as soon as I climbed up, two stones hit me, and then I saw a woman running away desperately.

One of the pebbles hit Wei Zhou on the forehead, and he was already bleeding. Seeing her masterpiece, Shen Rou apologized shyly: "Sorry, I thought it was ..."

"What do you think I am, a gorilla or a blind bear?" Zhou laughed, revealing two rows of white teeth, lined with blood and black mud on his face, which looked ridiculous.

Putting down his backpack and washing his face by the stream, Zhou Wei showed his true colors, a dark complexion that basked in the sun all the year round. Shen Rou took out the medicine box to dress his wound, and chatted, knowing that he and his companions were exploring in the wild, just separated by mountain torrents. Although Wei Zhou's backpack was big, he only dug out a pack of beef jerky for a long time and spread out his hand: "Food doesn't belong to my back. This pack of beef jerky was stuffed in before. "

With a map in one hand and a compass in the other, Wei Zhou said, "Since everyone is going to wucun, let's look for it all the way. Maybe they will wait for us when we arrive. " Gee, the sound of flesh-and-blood collision, Wei Zhou felt something cold around his neck. When he failed, it was a green snake more than one meter long.

Shen Rou noticed that Wei Zhou's face turned white in an instant, jumping in place like an electric shock, trying to throw the snake down. A great man who dares to explore is even afraid of snakes. Shen rou grabbed the green snake's seven inches and dragged it down from her neck.

"This is harmless," said Shen Rou. "Are you really here to explore?" There are so many snakes in Heizhugou, don't be scared to death.

Wei Zhou, who has just recovered from the shock, is far away from Shen Rou: "I am not afraid of anything else, I am afraid of snakes." Especially when snakes crawl on people, the chilly feeling makes them feel uncomfortable.

"Aren't you afraid?" Zhou Wei asked again, there are few women who are not afraid of snakes.

"There are many snakes in my house." As Shen Rou spoke, she saw Zhou Wei's discolored face again and explained, "My father is a professor of zoology and specializes in snakes."

"I thought your family had a snake farm."

"About the same. It is very comfortable to sleep with snakes in summer. " Shen Rou said, holding the dying green snake to her side. Wei Zhou waved desperately: "Please, keep it away from me!" With a hard hand, the green snake died and threw it into the bag. Shen Judo said, "This is dinner." Wei Zhou looked at her back, heart way it seems that the little girl can help, not a burden.

The two of them went south along the current. As soon as the sun set in the west, the forest darkened, the air became wetter and wetter, the fog became thicker and thicker, and there was thick moss under their feet, which made them slippery to step on. Be careful every time you check in, or you'll throw a dog at the mud. It began to rain. At first, it was very slow, but it turned into a stream, and the rain suddenly increased, making people unable to open their eyes. Unable to move forward, I just found a place to spend the night.

If you are lucky, you can sometimes meet wooden houses built by local Yi hunters. Unfortunately, they are not so lucky. In the end, only a rock protruding outward was found, forming a natural roof, barely enough for two people. Two people took out compressed biscuits and beef jerky and shared them. Wei Zhou took out a stainless steel cup and picked up some water. He took a few sips and handed it to Shen Rou. Shen Rou took a sip and picked up some water. Wei Zhou thought she was thirsty, but she took out medical scissors from her bag, cut the green snake into several sections and threw it into a stainless steel cup.

"What are you doing?"

"Cook it and eat it on the way." Shen soft look at his expression, as if to say, you * * *.

"Do you want to cook with my cup? ! "

"Yes, because I don't have a cup."

At night, the rain still hasn't decreased. Shen Rou sprinkled insect repellent around and covered their legs with raincoats.

"You should have a knife with you?" Shen asked softly.

Wei Zhou took it out of her bag and gave it to her for self-defense.

Shen Rou pulled the knife out of its sheath. The blade was about 20 cm long and said to Wei Zhou, "If you touch me, that green snake is your life."

Wei Zhou in distress situation, even if intentional, there is nothing he can do.

A pool of blood winds through the soles of your feet, faintly smelling of blood. Wei Zhou a surprised, this is definitely not last night to kill the snake shen soft left, he went out to see the guy in his hand. Blood flowed down from a slope on the right. Wei Zhou climbed up from a gentle slope on one side and found the blood source. It was the body of several sika deer, one of which was only skeleton, and the other was bitten off the whole head.

When were these sika deer killed? What kind of wild animals killed them? I don't think it was last night. Wei Zhou slept soundly and heard nothing. Probably yesterday during the day, the meat was still fresh, and the blood was washed down the mountain by the rain last night.

"What do you think this is?" Shen Rou woke up and found something unusual. She climbed the slope and squatted on the ground as if she had found something.

Wei Zhou will guy don't behind the waist, walked over to see. A big footprint, about 40 cm long, may be a bear's, but it looks more like a human from the outline. 40 cm long, even Yao Ming's footprints are not that big.

Shen Rou ran back and forth, holding her card machine in her hand. "Huh?" The camera obviously has electricity, and it was used a few days ago. Why is there no electricity now?

"Aren't you afraid?" Wei Zhou pointed to this big footprint, and she was still interested in taking pictures with a camera.

"Afraid." Shen Rou swallowed a mouthful of saliva. "But this is very precious information. Maybe there are savages in Heizhugou. Savages are better than beasts. " Shen Rou went back and tried the rest of the battery, but it was still dead.

"Maybe it's raining too hard." Wei Zhou cut a few pieces of venison and took it away. See shen soft a face of doubt, he was relieved. "Maybe it would be nice to get out in the sun." In the deep mountains and forests, many modern scientific and technological products are easy to fail.

The two continued on their way, and the mountain road was even worse.

Women's feelings seem more sensitive. Shen Rou tugged at Wei Zhou's sleeve and whispered, "I think there's something behind." Wei Zhou listened attentively and asked, "Are you hungry because you didn't eat enough in the morning?" But the right hand is behind the waist. After hearing what he said, Shen Rou also knew that she heard that kind of subtle voice like a growling stomach.

The bush suddenly moved, and a yellow thing jumped out, only a pair of scary eyes could be seen clearly.

"Run!" Wei Zhou let out a cry, pulled Shen Rou, turned and ran into the jungle. Shen rou didn't know what it was, but she was dragged forward, and branches, leaves and rattan hit her face, which was very painful. The more nervous the mountain road covered with moss at the foot, the more unstable it is. The whistling wind blew through my ear, and the guy behind me gasped and growled.

Peng, turned around and put a gun, hit the leopard's ear and directly pierced a hole. Leopard eat pain, shout at top of voice, but also awakened * * *, jumped toward the two of them.

There is a downhill slope ahead, and it is too late to stop. Besides, stopping will only become a leopard's belly meal. The soles of the feet slipped and the body lost its balance, and the two of them rolled down directly. I was hit by several trees on the way, but it didn't stop the rolling trend at all. I just feel dizzy, my back hurts, my chest hurts, and even my toes hurt.

(5)

The body suddenly vacated, lost its support, and then fell, reaching out and catching nothing. Dong, the destination is a piece of water, Shen Rou fluttered desperately, only to find that the water depth reached the waist.

They rolled down the slope and fell into the hole. This hole is more than ten meters deep from the ground, so it is impossible to get out of it. Wei Zhou turned on the searchlight, the hole continued to move forward, and the water continued to move forward. It turned out to be an underground river.

The water slowly brushed the skin, rolled down all the way and cut wounds, large and small, and felt a dull pain after soaking in the water. There was a sharp pain in my calf and I was bitten by something. I cried out in pain and I hurried out of the water. A white fish bit my calf, but I shook it twice and bit it tightly. The flashlight in Shen's hand relieved me. The rocks on the shore are wet, cold and slippery, and they lean against the cave wall, but they haven't recovered from the shock just now. This fish is only as long as the palm of your hand, but it is very fierce.

The fish that attacked people, the situation is a little bad. Wei Zhou asked her how the situation was, or whether to bandage the wound to stop bleeding. Shen Rou didn't say anything. Try to get out of this hellhole as soon as possible. Wei Zhou insisted on dressing to stop bleeding first, vaguely saying that the fishy smell might cause the fish to attack.

There is only a narrow passage against the cave wall, which is wet and slippery, and there is a slope that is not easy to walk. Wei Zhou dug out two steel pipes from his bag and handed them to Shen Rou. Shen Rou took it and secretly became suspicious. Just now, he was chased by a leopard, and Wei Zhou fired a gun. How can an ordinary traveler or explorer have a gun? Why are there two steel pipes in his bag? There are spiral mouths at both ends of the steel pipe, which obviously has other uses.

"Are you Doraemon? Everything is in the bag. "

"Because I am a professional explorer." Wei Zhou made a snap of his fingers, wondering if he recognized the implication of Shen Ruan. "Have you ever played baseball?" Zhou Wei asked again.

"No. Now is not the time to talk about this topic. "

"I think those little guys want to eat us." Wei Zhou stared at the water with a steel pipe in his hand, and his tone was relaxed, as if he were joking.

The water surface is changing, with layers of waterlines and white shadows. It's those white fish! Poof, one of them jumped out of the water, jumped out of the water more than 1 meter high, opened a huge mouth out of proportion to his palm-length body, exposed two rows of sharp teeth, and went straight for Wei Zhou.

Wei Zhou saw the target, waved the steel pipe, hit it with one blow, and the pioneer fish was hit into the water. The failure of the first fish actually gave them more powerful attack power. One jumped out, two jumped out and three jumped out. In front of them, a glistening ... steel pipe hit the fish, making a squeaking sound, which made people sick.

Constantly jumping out and being beaten back into the water, Wei Zhou said to Shen Rou, who was also waving a steel pipe: "You'd better not have intensive phobia!" The steel pipe swung out and hit a piece, and the smell of fish and blood came to my face. Shen Rou loudly replied: "Not before, but now!" My arm is starting to get sore, so even if I play baseball, I have to have an intermission.

While playing, the two men walked along the path along the shore and came to a relatively open flat land. No matter how powerful those fish are, they can't get ashore without boiling water. Shen soft a * * * sat down and rubbed his sour arm. Wei Zhou took a photo forward with a searchlight. All he can see is water, and no one knows how far ahead.

Knowledge point three

Karst caves: the formation of karst caves is the result of long-term dissolution of groundwater in limestone areas. Insoluble calcium carbonate in limestone can be converted into slightly soluble calcium bicarbonate under the action of water and carbon dioxide. Due to the different calcium content and erosion degree of each part of limestone layer, it is gradually dissolved and divided into independent, changeable, steep and beautiful peaks and caves, and the landscape is strange. The largest cave in the world is the Mammoth Cave in the Appalachian Mountains of North America. It is located in Kentucky, with a depth of 64 kilometers and a total length of 250 kilometers. The width of the cave is like a square, the narrowness is like a corridor, and the height is 50 meters high. The whole cave twists and turns in the plane and can be divided into three layers vertically.

Knowledge point four

Underground river: also known as "undercurrent", refers to the river below the ground and is a kind of underground karst landform. It is an underground river channel formed by underground water collection or surface water infiltrating into the ground along underground rock cracks, after rock dissolution, collapse and water delivery. Underground rivers can be seen in many places in the southwest provinces of China, and the scale is huge, such as the underground water system in Dongan County, Guangxi, and the underground river in Lianyun Dong Xiaoyu, Sichuan, where limestone is exposed. Some underground rivers have a large flow. For example, the underground river system in Du 'an, Guangxi, China has a total length of more than 50 kilometers, a catchment area of 900 square kilometers, and tributaries 13, with a maximum flow of 390 m/s in flood season.

The water level and discharge of underground rivers are unstable, and the difference between dry season and rainy season can reach 10 times or 100 times. Some underground rivers are fast-flowing, some fall into water or even waterfalls, and some can form underground lakes. Underground river water can be used for water supply, and underground hydropower stations can be built in some areas with large drop. The reason why the Yangtze River keeps flowing in winter lies in the supply of many underground rivers and groundwater. The development of underground river is the result of the interaction between crustal change and climate change, so it is an important and effective means to study the characteristics and development law of underground river.
