Three Sherpas, one guide, three team members, plus Jarrett Photographer, a total of eight people, the standard configuration for climbing Mount Everest.
It is worth mentioning that the photographer had to stay at the base camp due to health reasons.
"Damn it, it's so cold."
Yao Jun tightened his collar, and the cold wind blew in, as if his body was covered with ice.
Bifangha took a breath of hot air. White steam could still be seen in the headlight pole, but it was very small and seemed to be about to disappear. The temperature was already close to minus 20 degrees, and no white steam would appear no matter how low it was.
Rob took out the altitude measuring device: "It's now 1:47 in the morning, the altitude is 5432, come on, there are still 300 meters left, just cross the glacier."
Yao Jun asked: "Is it easy after crossing the glacier?"
Rob nodded, and the morale of the team instantly rose.
"The possibility of death is smaller after crossing the glacier."
Everyone: "."
Yao Jun tightened his hat, feeling that the weather was getting colder.
【Is this a bad joke?】
Even the audience felt a cold wind blowing over them, looking at the dark peaks in front of them, as if they were watching a group of people moving forward thinking about hell.
The dual torment of cold and lack of oxygen made everyone feel dizzy. Bi Fang followed the team at the end. As the last guarantee for the team, in front of him was Attenborough. Since he personally invited it, who should he let Bi Fangdu take the back seat?
Don't worry, you have to do it yourself.
"Five thousand four hundred meters. At our current speed, we can rise about one hundred meters every forty minutes. If there is no traffic jam, we should be able to reach Camp C1 around five o'clock." Bifang breathed in the air and said slowly.
, at this height and level, even with his physical fitness, it would be easy to disrupt the breathing rhythm if he goes too fast, resulting in a huge consumption of physical strength.
【Traffic jam?】
【What the hell is a traffic jam?】
The audience is confused, can there still be traffic jams on Mount Everest?
Bi Fang swallowed and nodded: "Because many places on Mount Everest are extremely difficult to climb and the route selection is very simple. Once the right time comes, many teams will climb together and block the route.
There was a traffic jam at 8,000 meters in 2019. I said before that above the South Col, at 7,600 meters, the human body begins to die slowly. What we have to do is to stop the body before it dies.
After climbing to the top and then returning, the traffic jam for 8,000 meters resulted in three deaths at once."
As if to verify what Bi Fang had said, a very familiar voice appeared.
"Hey, look, isn't this our big anchor? I thought you would just pay a hundred dollars to let the Sherpas carry you up the mountain!"
Bi Fang plucked his ears, and the moment he heard the sound, he knew who it was, and without saying anything, he followed the lord in front.
Sir Alex also heard the movement behind him, looked at Bifang, and then made a OK gesture.
Bi Fang shook his head: "Don't worry about him. If he feels strong, just let him shout."
If you talk nonsense while climbing a mountain more than 5,000 meters away, you may have frozen your brain.
A person can be strong and violent, or weak and gentle, but cannot be weak and violent at the same time. This is why many people hate Chihuahuas.
Bi Fang's reaction made the audience laugh like crazy. Originally, they were a little angry at the eccentric Withers, but Bi Fang's words suddenly made him look like a clown.
"Hey, hey! Can't you hear me?" Looking at Bifang who ignored him, Withers shouted twice in a row, but received no response.
Saito on the side crossed Withers and followed the large army. He glanced at Withers, the contempt in his eyes was self-evident, and made Withers' teeth itch with anger.
Saito shook his head and went up without looking back.
Although Saito was a little surprised that the two teams met again, it was not incomprehensible. Everyone came late and were in a hurry. It was normal for them to meet on the way on the third day after arriving at the base camp.
"Shit! Ahem."
Withers cursed secretly, and then he was filled with cold air, causing him to cough.
The snow is getting thicker and thicker. Not only does it take a lot of energy to pull out, but it is also difficult to know what you are stepping on when you step on it. It may be a stone, or it may be a bottomless glacier in the next second. This kind of blinding
The box feels very uncomfortable.
Yao Jun shook off the snow on his boots: "Grandma, is there no other way to go?"
Bi Fang affirmed: "Yes, the glacier on the north slope is more stable, there are not many cracks, and the road is built throughout. The risk of falling is low, the risk of rockfall and ice avalanche is also relatively small, the route between camps is short, and the risk of physical exhaustion is small; the climbing team
It’s also less and the risk of traffic jams is low.”
In comparison, the southern slope is a little colder. There is a huge risk of ice and avalanches on the Khumbu Glacier; there are serious rockfalls and icefalls on the Lhotse wall; there are many glacier crevices; the distance between camps is long and it is easy to overdraw; there are many climbing teams on the south side.
Traffic jams are easy.
"Then why don't you go to Bei Slope?"
Bi Fang rolled his eyes.
Yao Jun suddenly realized: "Damn it, I remember, Beipo wants a certificate, cough cough, damn, I feel so uncomfortable."
Yao Jun, who kept talking, coughed violently. Rob in front quickly handed over the oxygen tank, helped Yao Jun to the side, and breathed for a few minutes before he recovered. When he put away the oxygen tank, Yao Jun was still very reluctant to let go.
"Wait a minute, let me take another breath, just one breath, huh, ha, feel good, feel good."
Bi Fang touched his chin and said hesitantly: "You have a bit of kombucha cough? It was the same when you went to bed last night. You were coughing all night, so you didn't sleep, okay?"
"Ah?" Yao Jun was startled, and just about to stuff the oxygen bottle back into his bag, he hugged it tightly in his arms.
Because the air near the Khumbu Glacier is dry and cold, the lungs are prone to inflammation, so many people suffer from a persistent cough, which is called "Kumbu Cough". Once this symptom occurs, you cannot continue climbing and can only go down the mountain.
Waiting for rescue.
Rob on the side waved his hand: "Mr. Yao's reaction is still normal. Although the frequency is very high, it is related to our tight schedule. Lambu cough has already damaged the trachea, and it cannot be relieved by taking a few breaths of oxygen."
Rob has rich experience and has led many teams so that he has sufficient experience in judging the symptoms of team members. Although the frequency and symptoms of Yao Jun's cough have reached the category of laminaria cough, it still depends on the specific situation and he can climb the mountain directly without adapting.
People like Yao Jun are already in a better situation, but it is abnormal for people like Bi Fang to seem to have no trouble.
No matter how experienced climbers are, they will experience some discomfort in the first few days after reaching high altitudes, to a greater or lesser degree, but no one is immune.
When Yao Jun and others first arrived at the base camp, they would sometimes feel dizzy even if they did nothing, let alone Bifang after exercising.
After finishing training yesterday, Rob looked at Bifang's back and felt almost like a dog in the sun. He was full of doubts: "Can this guy survive without oxygen?"
Fortunately, Bifang's breathing was also a little rapid at this time, which made Rob give up the idea that the other party was a robot and did not rely on oxygen but electricity.
In fact, Rob guessed wrong. Bifang was not unresponsive. Even though the maximum oxygen uptake may have exceeded 80, it was not at the level of a monster after all. The only problem was that Bifang's strength was due to his adaptability and attention to breathing methods.
.
Bi Fang's breathing is not simply a matter of exhaling step by step and inhaling step by step. It is adjusted almost all the time from amplitude to rhythm, abdominal breathing, reverse abdominal breathing, etc.
The wilderness traveler has almost engraved many things in Bifang's DNA. No matter what harsh environment he encounters, Bifang can always use various subtle ways to adjust his body to the best.
Orange-level skills allow Bi Fang to clearly know when to run, when to walk, when to drink water, and when to replenish energy... Even though these things look simple, they are actually very scary.
thing.
An entry-level marathon runner who has been running for three or four years may only be able to estimate when he should replenish himself in a simple environment such as road running to avoid a sudden power outage. But Bi Fang has already understood his body and environment.
It's far beyond ordinary people's imagination, which is why he can travel lightly through the forest and cover hundreds of kilometers.
To be strong is to be free.
Bi Fang nodded and said no more: "Pay attention to keeping your mouth and neck warm, and drink more water. Drink a lot of water."
After a few simple instructions, everyone moved forward again. At about three o'clock in the morning, everyone finally arrived at the edge of the Khumbu Glacier.
"Thousands of glaciers flow here day and night. Some ice towers are even taller than buildings, and there are also bottomless cracks. You definitely don't want to fall in. The ladder you set up the day before and the route you took out,
It might be completely unusable by the next day, so we have to crawl through it as quickly as possible."
Rob gasped and grabbed the ascender on the side. They were going to use this to climb up the glacier.
"Wait, flow? Does the glacier flow?" Yao Jun was a little confused, feeling as if he heard something that subverted his three views, "Is it something like an avalanche?"
"No." Bifang shook his head, "glaciers do move."
On the tops of some of the world's tallest mountains, as long as there is perennial snow, there is a possibility of glaciers appearing.
There are glaciers distributed in my country's Tianshan Mountains, Kunlun Mountains, Qilian Mountains, the Himalayas on the southwest border, the European Alps, the Antarctic continent and the Arctic Alaska and Greenland.
In places like Antarctica and Greenland, they are called continental glaciers, while glaciers flowing in mountains and valleys are called mountain glaciers.
"There's a story about this."
Bi Fang also came to the ascender, looked at the bottomless abyss under his feet, breathed out the thin and pitiful white mist and said: "More than a hundred years ago, the Europeans living in the Alps did not know that in their
The ice in the valley around me was moving slowly.
There is a very beautiful wild rose growing in the Alps. The locals have a custom that when a young man woos the girl he loves, he has to risk his life to go over the mountains and ridges to collect roses and present them to the girl to express his love.
Brave and loyal.
At the beginning of the 19th century, several young men went to the mountains to pick flowers, but never came back. Because they were buried in thousands of years of ice and snow by an avalanche. The unfortunate news brought great pain to the villagers down the mountain. As a result, a glacier researcher
The reporter comforted them and said that in about 40 years' time, the bodies of these young people would appear at the front of the glacier.
At that time, the villagers did not know that the glacier could move. After hearing the scholar's words, they only felt angry and funny. What was unexpected was that 43 years later, people actually found these unfortunate young people at the front of the glacier.
Not only did the glacier bring these corpses to the villagers, but because they were refrigerated under the ice, the corpses did not rot or deteriorate. It is said that one of the young men was holding a rose tightly in his hand."
[Strange knowledge has been added...]
[How come Lao Fang knows everything? Is this what you can know? 】
【you know too much】
"The flow of glaciers is not easy to detect because it flows very slowly. The speed of glacier flow is determined by the thickness of the ice layer and the slope of the terrain. The flow speed of each glacier is different, but they are all very slow, only a few centimeters per day. At most, it's only a few meters. There is a Rongbuk Glacier about 20 kilometers long on the north slope of Mount Everest in my country. Chinese scientific workers conducted observations from 1966 to 1968 and found that the annual movement speed of the Rongbuk Glacier is 117 meters, with a daily movement rate of 117 meters. Only flows 0.3 meters.”
Bi Fang tightened the safety rope tightly on his body and looked at the abyss under his feet, constantly inhaling to increase his blood oxygen level.
[So why is it moving?]
"It's very simple. The col located on the top of the mountain is often the source of the glacier. This is called the 'snow basin'. The snow particles falling from the sky will first gather in the snow basin. After being heated, the surface layer will melt and the melted water will penetrate downward.
Freezing the snow particles; the thicker the snow accumulates, the lower layer of snow will recrystallize under pressure. Over time, it becomes glacier ice. However, glacier ice is formed under pressure, which is different from natural ice.
The most important thing is that there are many gaps inside the glacier ice, and the gaps are filled with air. Each ice crystal is also wrapped with a thin layer of liquid water. This is like coating the ball bearings in a machine with lubricating oil. Therefore,
Glacier ice is more easily deformed than natural ice, that is, it has better plasticity.
This plasticity is the real reason for the movement of glaciers. Under the influence of gravity on a certain slope, plastic ice will change the shape of the glacier and slowly move down the valley. The flow of glaciers in valleys is the same as that of rivers. It flows fast in the middle and between the two sides.
The side flow is slow. If you insert a row of wooden piles across a glacier, over time, you will see that the middle of the row of wooden piles protrudes downstream and becomes curved."
Bi Fang stepped forward and held an ascender similar to a bus handle. This simple tool has an eccentric device inside. It can produce one-way movement with the rope and can tighten it in time.
Hang up the safety hook and shine your headlight downwards. You can't see the end at all. This may be a glacier with a depth of tens of meters. Once you fall into it, you are very likely to die on the spot. Even if you don't die, you may freeze to death on the spot.
Bi Fang tightened his grip on the handle, shifted his body weight forward, kicked off his legs suddenly, and the ascender and the rope quickly rubbed and slid.
The wind howling in the valley, the man holding the rope, the bottomless abyss, everything flew by with the cold wind in my ears.
