Live Wilderness Adventure

Chapter 403 Avalanche Survivor

"The smell of blood? Where is it?"

Yao Jun shrugged his nose, but he didn't smell anything. The weather was so cold, every breath felt like a knife was cutting back and forth in his nasal cavity. It really smelled like blood, it was his own blood.

"Is the detector responding?"

Bi Fang adjusted the detector again, but there was no response.

Yao Jun touched his head strangely: "No response, is there anyone around?"

"It may be that the detector is lost, or the other party may not be prepared, but I do smell blood, which is very strong."

"But I didn't smell anything." Yao Jun sniffed vigorously, but there was still nothing. "It's such a cold day, the blood is frozen, right? The smell is wafting out? Dog's nose, right?"

"Don't ask, it's talent to ask." Bi Fang didn't explain much, but with a more cautious attitude, trotted along the smell in the air.

When crossing a small slope, Bi Fang sharply retracted his right foot and stopped Yao Jun and Jarrett behind him.

"Be careful, there are glaciers."

As he spoke, he stretched out his trekking poles and poked it on the snowdrift in front of him. Under the weak force, the snow slope quickly collapsed, splashing countless white smoke and dust. Under the sunlight, a bottomless deep blue glacier appeared In front of everyone.

The audience was dumbfounded, they just looked at the snow slope in front of Bi Fang, and couldn't see any signs at all. If it was an ordinary person, wouldn't this kick just stop?

How the hell did Fang Shen see it without any warning signs?

[Fuck, how the hell did you find out? 】

[X-ray, Fang Shen used x-ray! 】

[What the hell is x-ray, have I entered the sci-fi channel? Is it in the river? 】

[New fans don’t know, Lao Fang is our country’s secret weapon. He has undergone physical transformation, his eyes can shoot X-rays, and can be seen easily. There is a verbal agreement within our army that the enemy will not use nuclear weapons, and our side will not use them. Fang Shen! 】

[Is it impossible to hide the matter of the ultimate weapon? 】

"Of course you can't tell just by looking at the pile of snow in front of you, but you should take a longer view."

Hearing Bi Fang's words, the photographer far away at the base camp immediately flew the drone to take pictures of the hillside. Under the condition of infinitely widened vision and good light, everyone finally saw the difference.

On the snow slope, another scar-like snow line raised slightly, leaving some shadows under the sunlight. Although it was very shallow, it became conspicuous once the line of sight was widened.

"It is difficult to find glaciers covered by snow. Every year, many people are buried because of such glaciers. However, a wider view can form a more comprehensive understanding. When such a streamlined glaciers appear in front of you You need to be more vigilant when it comes to the snow line, besides the snow line, you can also judge by the color.”

Bi Fang grabbed a handful of snow from the edge of the crack, took a few steps back and put it on the ground.

The audience's eyes widened, and after careful comparison, they gradually discovered that the snow on the edge of the crack seemed to be darker in color?

[The snow on the edge of the crack is darker? Is this an illusion? 】

"It's not an illusion. We call this kind of glacier crack covered by snow a dark crevice. Except that it is slightly lower than the surrounding line, you can observe the shadow line from a high altitude during the day. It is distinguished by the color of the snow. The dark crevice The snow will be slightly yellowish or black in color."

"Is it so miraculous? What's the reason?" Yao Jun listened with gusto, grabbed a handful of snow and licked it.

Do you feel no difference?

Same ice teeth.

Bi Fang chuckled, "Guess what?"

"If I knew, I wouldn't be following your ass."

"It's the specific heat capacity." Bi Fang patted the snow in his hand, "Under the crack is the air that cannot circulate, and the specific heat capacity is larger than that of the rock. The temperature difference causes the ice crystal rate and density of the snow to be different, the refractive index changes, and the color becomes darker." gone."

what?

The audience was dumbfounded.

【I already thought that Bi Fang knew a lot, but unexpectedly, I still underestimated him. 】

[Specific heat capacity, my mother, I can't think of a reason for the rest of my life. . 】

【Is this the boss, trembling】

Bi Fang walked along the crevasses of the glacier, trying to find out if there were any aluminum ladders left by the Sherpas.

"Generally, the depth of glacier cracks is 25-30 meters. This is obviously deeper, and the ice layer beyond this depth is stronger. The further you go down, the ice crystals will become larger and stronger, and the adhesion will become stronger. After being tried to make it When separated by pressure, its internal structure will become more compact due to pressure, and the shape will look like thick cream or syrup."

"In fact, the best way to cross the glacier is to go around it. Going in a circle is much safer than crossing it. The next best thing is to choose a snow bridge. The deep snow in winter will become hard under the blowing of strong winds, and it may form The snow bridge over the crevasse will not melt until summer. There is also a more solid snow bridge, but it is not a snow bridge anymore, it is a slender isthmus connecting two crevasses."

[What is an isthmus? 】

[It is a narrow land that connects two continents, such as the Panama Isthmus between the South American continent and the North American continent. That is a typical isthmus, but the isthmus that connects the ice crevasse is relatively rare, at least I have not seen it much]

[Brother Bullfrog, what are you doing? 】

[Geological surveyor, my colleague told me that there was an avalanche live-streamed by a colleague in the morning, and he also performed a textbook-style self-rescue. If you feel curious, come and have a look. The anchor is really good. Although I haven’t watched it for a long time, it is very professional and has some knowledge. I don't even know. 】

Lao Deng stroked his glasses and typed this passage on the computer.

The snow on the dark crevices of the glacier will be darker because of the specific heat capacity. Although I have not worked for a long time and the main direction of attack is not the glacier, but I know more about it than ordinary people. This kind of knowledge really opened his eyes. The impulse to fly to Mount Everest to study glaciers.

"This phenomenon cannot be discovered through simple research and investigation, but requires a lot of experience accumulation. Where did this guy come from?"

[There are really all kinds of people watching the live broadcast. A big hacker came out yesterday, and a geological prospector came today]

[Didn’t there still be professors of biology and history before? (dog head)]

["Thriving"! 】

Unfortunately, Bi Fang did not find the aluminum bridge left by the Sherpas, only the nail holes left by the glacier. The aluminum bridge should have been washed away by the avalanche last night.

But luckily, Bi Fang found a snow bridge.

Very wide and thick, it looks like a road has been built.

"When encountering a snow bridge, observe carefully from the side before stepping on it. The pit must not be thin, and then try to go up to the field to detect it. Be careful. Some team members should ask the team members to ensure that the posture is tight and the rope is tightened to prevent snow. The bridge suddenly broke and fell into the crack. After the first team member passed, the other team members could strictly follow the leader's footsteps after another team member tightened the rope to ensure."

"The firmness of the snow bridge is mainly affected by the temperature. In the cold winter season or in the early morning, the snow bridge may be strong enough to support a truck. After the snow melts in the afternoon, it may not even be able to support its own weight. Every time you pass the snow bridge, you must be vigilant. If you pass safely in the morning, it doesn't mean you can pass safely in the afternoon."

"Tighten it up." Bi Fang turned to Yao Jun and Jarrett.

The two nodded and lowered their center of gravity at the same time, the crampons were firmly embedded in the ice.

Bi Fang took a deep breath and was about to step out when a bloody hand pressed against the ice surface a few meters away from the edge of the glacier. The blood quickly condensed into bloody handprints and sharp ice crystals grew.

Bi Fang's pupils suddenly contracted.

"Go and save people!"
