Live Wilderness Adventure

Three Sherpas, one guide, three team members, a total of seven people, is the standard configuration for climbing Mount Everest.

"His sister, it's so cold."

Yao Jun tightened his neckline, and the cold wind rushed in, as if ice had formed on his body.

Bi Fangha let out a breath of hot air, and white steam could still be seen in the headlight column, but it was too little, as if it was about to disappear, the temperature was already close to minus 20 degrees, and even the white steam would not appear no matter how low it was.

Rob pulled out the altimeter: "It's 1:47 in the morning, the altitude is 5432, come on, there are still 300 meters, it's good to pass the glacier."

Yao Jun asked, "Is it easy to cross the glacier?"

Rob nodded, and the morale of the team rose instantly.

"It's less likely to die after the glacier."

Everyone: "..."

Yao Jun tightened his hat, feeling that the weather was getting colder.

【Is this a cold joke? 】

Even the audience felt a cold wind blowing through them, looking at the dark peaks ahead, as if watching a group of people thinking about hell.

The double torture of cold and lack of oxygen made everyone feel a little dizzy. Bi Fang followed at the back of the team. As the last guarantee of the team, Attenborough was in front of him. Since he personally invited him, who should be at the rear, Bi Fang? Don't worry, you can only come by yourself.

"5,400 meters, at our current speed, we can ascend about 100 meters every 40 minutes. If there is no traffic jam, we should be able to reach the c1 camp around 5:00." Bi Fang breathed the air and said slowly. , At this height and situation, even with his physical fitness, speaking too fast can easily disrupt the breathing rhythm, resulting in a substantial consumption of physical strength.

【Traffic jam? 】

[What the **** is a traffic jam? 】

The audience is confused, is there still traffic jam on Mount Everest?

Bi Fang swallowed his saliva and nodded: "Because it is extremely difficult to climb to many places on Mount Everest, and the route selection is very simple, once the right time comes, there will be many teams climbing together, blocking the route. In 2019, there was a traffic jam at 8,000 meters. As I said before, above the South Col, 7,600 meters above, the human body begins to die slowly. What we have to do is to prevent the body from dying. Climbing to the top and then returning, the result of the 8,000-meter traffic jam resulted in three deaths at one time."

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 pay a hundred ugly money to let the Sherpas carry you up the mountain!"

Bi Fang took out his ears. The moment he heard the voice, he knew who was coming. He didn't say anything, and just followed the lord in front of him.

The Lord also heard the movement behind him, his eyes gestured to Bi Fang, and he made a gesture of whether it was OK.

Bi Fang shook his head: "Don't worry about him, if he thinks he has more strength, let him shout."

More than 5,000 meters away, I am afraid that my brain is not frozen.

A person can be strong and grumpy, or weak and gentle, but not weak and grumpy, which is why many people hate Chihuahuas.

Bi Fang's reaction made the audience go crazy with laughter. He was a little angry at Withers, who was yin and yang, but Bi Fang's words made the other party look like a clown all of a sudden.

"Hey, hey! Can't you hear?" Looking at Bi Fang, who ignored him, Withers shouted twice in a row, but got no response.

Saito, who was on the side, crossed Withers to keep up with the large army, and glanced at Withers, the contempt in his eyes was self-evident, and Withers' teeth tickled with anger.

Saito shook his head and went up without looking back.

Although Saito was a little surprised by the re-encounter of the two teams, it was not incomprehensible. Everyone came late and was in a hurry. It was normal to meet on the third day of the base camp.

"shit! Cough cough."

Withers scolded secretly, and then the cold air filled his mouth, causing him to cough.

The snow is getting thicker and thicker. Not only does it take a lot of energy to pull it out, but it is difficult to know what exactly 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 blindness The box feels bad.

Yao Jun shook off the snow on his boots: "Grandma's, is there no other way to go?"

Bi Fang affirmed: "Yes, the glacier on the north **** is more stable, there are not many cracks, and the road is built throughout the process, the risk of slipping is low, the risk of rockfall and ice avalanche is relatively small, the route between camps is short, and the risk of physical overdraft is small; climbing team There are also fewer, and the risk of traffic jams is low.”

In contrast, the southern **** is slightly chilly, and there is a huge risk of ice and avalanche on the Khumbu Glacier; rocks and ice on the Lhotse Wall are very serious; there are many cracks in the glacier; the distance between the camps is long and easy to overdraw; Easy to get stuck in traffic.

"Then why don't you go to the North Slope?"

Bi Fang rolled his eyes.

Yao Jun suddenly realized: "Damn, I remember, Beipo wants a certificate, ahem, shit, it's so uncomfortable."

Yao Jun, who was talking continuously, coughed violently. Rob in front of him quickly handed over the oxygen tank and helped Yao Jun to the side.

"Wait, let me take another breath, just one breath, huh, ha, cool, comfortable."

Bi Fang touched his chin and said hesitantly, "Do you have a kombu cough? You slept last night, too. I have been coughing all night, haven't you slept?"

"Ah?" Yao Jun was startled, he just wanted to stuff the oxygen bottle back into his bag, and 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 show a state of persistent cough, known as "Kumbu cough". Once this symptom occurs, it is impossible to continue climbing, and can only go down and wait for rescue.

Rob on the side waved his hand: "Mr. Yao is still a normal reaction, although the frequency is very high, but this is related to our tight schedule. Kumbu cough has already damaged the trachea, and it is impossible to relieve it by taking a few breaths of oxygen."

Rob has rich experience, and many teams he has brought have given him sufficient experience in judging the symptoms of team members. Although Yao Jun's cough frequency and symptoms have reached the category of kelp cough, he still depends on the specific situation and climbs directly without adaptation. Yao Jun is already in a better situation, but it is abnormal for Bi Fang to have nothing to do with it.

Even experienced climbers will experience discomfort in the first few days of reaching high altitudes, more or less, but no one is immune.

When Yao Jun and others first arrived at the base camp, even if they did nothing, they would sometimes feel dizzy, not to mention Bi Fang after exercising.

Rob, who finished training yesterday, looked at Bi Fang's back, almost like a dog in the sun, full of doubts in his heart: "Can this guy survive without oxygen?"

Fortunately, Bi Fang's breathing was also a little short at this time, which made Rob dispel the idea that the other party was a robot and did not rely on oxygen and electricity.

In fact, Rob guessed wrong, Bi Fang is not unresponsive, even if the maximum oxygen uptake may have exceeded 80, but it is not the level of a monster after all, the only problem is that Bi Fang is strong and adaptable and pays attention to breathing .

Bi Fang's breathing is not as simple as exhaling step by step, inhaling step by step, from amplitude to rhythm, abdominal breathing, reverse abdominal breathing and so on are adjusted almost all the time.

The Wilderness Traveler has engraved many things into Bi Fang's DNA. No matter the harsh environment, Bi Fang can always use various subtle ways to adjust his body to the best.

The orange-level skills allow Bi Fang to clearly know when to run, when to walk, when to drink water, and when to replenish energy... Don't look at these things that seem simple, but they are actually very terrifying thing.

An entry-level marathon runner, who has run for three or four years, may only be able to estimate when he should replenish his supplies in a simple environment like road running so that the power supply will not be suddenly cut off, and Bi Fang has already understood his own body and environment. Far beyond the imagination of ordinary people, this is why he can travel lightly through the forest and travel hundreds of kilometers.

Power is freedom.

Bi Fang nodded and said no more: "Pay attention to keeping your mouth and neck warm, and still drink more water, drink a lot of water."

After a few simple instructions, everyone moved forward again. At about three in the morning, everyone finally came to the edge of the Khumbu Glacier.

"Thousands of glaciers flow day and night here, and some ice towers are even taller than buildings, and there are bottomless cracks. You definitely don't want to fall in. The ladder you built the day before and the route you walked out, It might be completely unusable by the next day, so we need to crawl through somewhere as quickly as possible."

Rob was panting, grabbing the ascender on the side, they were going to use this to climb the glacier.

"Wait, flow? Will glaciers flow?" Yao Jun was a little confused, feeling as if he had heard something that subverted the three views, "Is it something like an avalanche?"

"No." Bi Fang shook his head, "glaciers do move."

On the tops of some tall mountains in the world, as long as there is perennial snow, there will be the possibility of glaciers.

Glaciers are distributed in the Tianshan Mountains, Kunlun Mountains, Qilian Mountains in my country, the Himalayas on the southwestern border, the Alps in Europe, and Alaska and Greenland in the Antarctic continent and the Arctic.

In places like Antarctica and Greenland, they are called continental glaciers, and glaciers flowing in mountain valleys are called mountain glaciers.

"There's another story about that."

Bi Fang also came to the ascender, looked at the bottomless abyss under his feet, and said with a thin and pitiful white mist: "More than a hundred years ago, Europeans living in the Alps didn't know that in their The ice in the valley around me was moving slowly.

And there is a very beautiful wild rose in the Alps. The local people have a custom, that is, a young man woos a beloved girl, risking his life, going over mountains and mountains to collect roses and present them to the girl to show his bravery and loyalty.

In the early 19th century, a few young men went to the mountains to pick flowers, but they 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 at the foot of the mountain. As a result, a glacier researcher reassured them that in about another 40 years, the bodies of these young people would appear on the front of the glacier.

The villagers at that time didn't know that the glacier would move. After listening to the scholars' words, they felt angry and amused, but what was unexpected was that 43 years later, people really found these unfortunate young people at the front of the glacier.

The glaciers not only brought these corpses to the villagers, but also because of the cold storage under the ice, the corpses did not rot or deteriorate. One of the lads is said to be holding a rose in his hand. "

[Strange knowledge has been added. . . 】

[How can Lao Fang know everything, this is what you can know too? 】

【you know too much】

"Glacier flow is not easy to detect because it flows very slowly. The speed at which the glacier flows is determined by the thickness of the ice and the **** of the terrain. At most, it is only a few meters. There is a Rongbuk Glacier about 20 kilometers long on the north **** of Mount Everest in my country. Chinese scientists observed it from 1966 to 1968. The results measured that the Rongbuk Glacier moves at a speed of 117 meters per year. Only flows 0.3 meters."

Bi Fang fastened the safety rope tightly around his body, watching the abyss beneath his feet and breathing in continuously to increase the blood oxygen level.

【So why do you move?】

"It's very simple. The cols located on the top of the mountain are often the source of glaciers, which is called the 'grain snow basin'. Snow particles falling from the sky will first gather in the grain snow basin. Freezes snow grains; the thicker the snow accumulates, the more the underlying snow recrystallizes under pressure. Over time, it becomes glacial ice. But glacial ice is formed by compression, unlike natural ice.

The most important thing is that there are many voids inside the glacier ice, and the voids are filled with air. A thin layer of liquid water is also wrapped around each ice crystal. It's like putting oil on the ball bearings in a machine. Therefore, glacial ice is easier to deform than natural ice, that is, it has better plasticity.

This plasticity is the real reason glaciers move. Under the gravity of a certain slope, the plastic ice changes the shape of the glacier, moving slowly down the valley. Glaciers flow in valleys like rivers, with fast flow in the middle and slow flow on both sides. If you insert a row of wooden stakes horizontally on a glacier, over time, you can see that the middle of the row of wooden stakes protrudes downstream and becomes curved. "

Bi Fang stepped forward to hold an ascender similar to a bus handle, a simple tool with an eccentric inside. It can produce one-way movement with the rope and can also tighten in time.

Hook up the safety hook and look down with the headlight, and there is no end in sight. This may be a glacier with a depth of tens of meters. Once it falls into it, it is very likely to die on the spot. Even if it does not die, it may freeze to death on the spot.

Bi Fang clenched the handle tightly, moved his body's center of gravity forward, kicked his legs violently, and the ascender and the rope quickly rubbed and slid.

The wind of Wu Howling Valley, the person holding the rope, the bottomless abyss, everything flies away with the cold wind in the ear.

"Wuhu!"
