Liu Danqing walked along the edge of the ice cave, and said as he went: "This kind of ice cave is naturally formed, and in spring and summer, the melting snow water flows into this glacier, because the water temperature is higher than the ice, so these channels are created." ”

"They're like tunnels under the glacier, at first it's just a small gap, but when they gradually expand, they form such ice caves, this is a mini ice cave, a bigger blue ice cave, known as the world's first, absolutely beautiful, if we have the chance, we will go in and take you to see it." ”

Seeing Xiao Weiwei standing in the middle of the ice cave, Liu Danqing hurriedly pulled her to the side: "Weiwei, let's stand on the side, the middle is dangerous, look at it." ”

Following the direction of Liu Danqing's finger, I only saw that there were countless blue ice flakes like fish scales on the top of the ice cave, and one end of some ice flakes had begun to hang in the air.

"Those are blue ice, a very old ice, very beautiful, but also the most dangerous, hard like steel, and at the same time fragile like glass, very easy to break and fall off. ”

"So I don't want to stay here long, but because of the snowstorm outside, we're stuck here, so we have to settle for the edge of the ice cave, which at least has solid walls. ”

"If we hear a click, we have to rush out of the ice cave, which looks solid but can collapse at any moment. ”

"Last year, a climber was in such an ice cave, and he used the ice cave as a good shelter, but he didn't expect 150 tons of ice to fall off in an instant, and there was no suspense. ”

The blizzard came and went quickly, and in the ice cave, less than an hour after the two of them, the whining wind outside began to quiet.

Liu Danqing walked to the entrance of the cave and looked, losing the wind and wind, his vision was much better, at least he could see the scene in the distance.

"Eventually, our horizons were broadened, so that I could look for a reference, and our goal was to the east, to the east was the sea, and between Vatnajökull and the sea, there was a ring road, and if we found that road, we would be able to return to human society. ”

"Look, there's a place over there that's smoking, and you can see the smoke from so far away, and it should be a crater, and maybe there's a hot spring, and it's located to the east of us, so it's a reference. ”

"Weiwei, let's go, we have to speed up, at least before dark, go down to the lower ground, and look for a place to build shelter. ”

"The temperature here is about minus 10 degrees now, and at night, the temperature drops sharply to minus 20 or 30 degrees, and without a better shelter, our nights will be difficult. ”

The road down the mountain was long, along the way, the two of them didn't even talk much, just cared about covering their heads and hurrying, when they came to a steep slope, Liu Danqing greeted Xiao Weiwei, sat on the snow, and slowly began to slide down.

Xiao Weiwei also did the same, and the two of them slid down one after the other, up and down.

When accelerating, bring your feet together and paddle your hands as oars, giving your body a forward force.

When slowing down, spread your feet open to increase the friction, and at the same time put your hands into the snow to continue to increase the friction.

"Now we're skiing down a lot faster, otherwise it's very difficult to get up the slope, but it's only good for when visibility is very high. ”

"Stop!"

Liu Danqing shouted, opened his legs suddenly, plunged his hands into the snow, and braked the car.

After Xiao Weiwei heard the shout, she also braked the car with the same braking method and got up.

"Wow, it's dangerous, how can there be such a big cliff here?"

Liu Danqing motioned for Xiao San to fly to the front and showed everyone the scene in front of him, only to see that the slope came to an abrupt end more than ten meters in front of the two of them, turning into a steep cliff, and the bottom of the cliff was at least fifty meters away from the two.

"I'll go, if there is no brake, Qingye and Weiwei will hang up, terrifying!"

"This Iceland is really a good place, even to the young man and the slight dismount. ”

"Qing Ye and Weiwei should come back, change places for live broadcasts, this ghost place, if something happens, there is no time to rescue. ”

Not mentioning the audience's worries, Liu Danqing took a few steps forward and explained: "This should be the section of the glacier, look at the bottom, the undulating should be the ice shell formed by the broken ice after countless years of accumulation." ”

"Weiwei, we're walking sideways from the side, which looks better over there. Glaciers are the most irregular of all terrains, and this has to do with the fact that they are made up of ice blocks, which can break apart at any time or merge to create a variety of terrains. ”

Cautiously walking to the slope more than two hundred meters away, the two did not sit down to ski, because the terrain here is relatively gentle, and it cannot generate enough gravity to allow the two to descend quickly.

After another wordless journey, the two hurried with their heads covered and rushed towards the smoking position.

Soon, more than three hours passed, and they also descended to the bottom of this iceberg.

Reaching the bottom of the iceberg does not mean that the road is easy to walk, the terrain here is undulating, high is a smooth ice surface, and the curved surface makes it impossible to stand on it.

At the lower level, there was snow, and the two could only walk on the snow as much as possible.

For the rest of the trip, the two of them just looked at the reference object and kept going around.

Sometimes they use their hands and feet together, climb onto one ice surface, and then paddle over the other side.

It is not without danger here, and Liu Danqing, who opened the road in front, stopped again.

"Look, there's a crack in the ice, and now all we can see is a small black hole, but it means that this trail is dangerous. ”

"The crevasse is one of the most dangerous terrain on Vatnajökull glacier, which swallows up a dozen climbers every year, and they often lie in ambush under the snow, like this one in front of me, which has a name, called Snow Bridge. ”

"No one knows how thick the snow bridges are under your feet, and if they're thick, they're the same as normal ground, but if the ice is thin, then humans can fall down, and the depth of the ice crevasses is often tens or even hundreds of meters, and it's very narrow, which means that the likelihood of falling and then escaping is very low. ”

Xiao Weiwei also walked over, looked at the hole, pulled the safety rope in her hand, and said with a smile: "So we have this safety rope, so that even if one person falls into the ice cave, the other person can immediately fix himself and find a way to pull his teammates up." ”

"Yes, so we're going to carry this safety rope, it's our lifeline, we don't have a snow axe, which makes it all the more important. ”

Looking up at the sun, Liu Danqing continued: "Now the daily sunshine time here is about 8 hours, according to the position of the sun, we still have two to three hours of daylight, let's move on." ”

In more than two hours, Liu Danqing and Xiao Weiwei walked out of this undulating ice surface and entered a downward hillside again.

Looking at the sky, Liu Danqing turned his head to Xiao Weiwei and said, "Weiwei, we have to find a place to camp, the sun is still half an hour at most, we must find shelter." ”

Xiao Weiwei looked around and said, "There is a raised snow slope there, let's go up and see if there is a suitable place nearby." ”

The two of them walked up to the snow slope and looked around, there was a vast white snow around them, and there was no gray-brown land in sight, let alone green plants.

Sighing, Liu Danqing looked at the snow slope under his feet and said, "Let's build a shelter here, the snow here is relatively thick, and we will go to the shelter in the east." ”

"Iceland is located in the westerly wind, so the westerly wind prevails all year round, especially in the higher ground, we crossed the ridge in the morning and headed east, so the wind here is much lighter, but in order to keep warm, it is necessary to put the entrance to the shelter in the east shelter. ”

With Xiao Weiwei, Liu Danqing walked to the bottom of the snow slope and began to dig up the snow.

"Weiwei, I'll dig for a while, and then you will dig, the most important thing for us now is not to sweat, once the sweat wets the underwear, our body temperature will pass much faster, which will waste the energy that we can't replenish for the time being. ”

Liu Danqing explained to Weiwei, then stopped talking, and began to dig the snow cave, digging for about ten minutes, most of Liu Danqing's body had been drilled into the snowdrift.

At this time, he retreated and said, "Weiwei, you can dig for a while, there are no tools, and you are too tired to dig snow purely by hand." ”

When Xiao Weiwei got into the snow cave and began to continue digging, Liu Danqing continued while putting the dug snow blocks aside: "The snow here is different from the snow we usually come into contact with, they are semi-powdered and semi-crystalline. ”

In his spare time, he pressed some snow into a snow brick and said with a smile: "The snow bricks used by the Eskimos to build the snow hut may be made of this kind of snow, and they are so easy to press, very easily, they can become very tight, if you use tools, it will be even simpler." ”

After Xiao Weiwei dug for another ten minutes or so, Liu Danqing went into battle again and finally dug the snow cave before dark.

Compared with the snow huts dug in the snow on the China-Myanmar border, the snow cave this time is very simple, a semi-circular, fifty or sixty centimeters high, two meters long small hole.

The two got into the snow cave, and Liu Danqing turned his body hard and blocked the hole with a few snow blocks, leaving only a small gap.

"Look, that's why I had to choose the leeward side, because in order to ensure the oxygen in the cave, we had to leave a little gap at the entrance of the cave, and if it was in the windward area, the cold air would freeze the two of us. ”
