Chapter 400 Avalanche Survivors
"The smell of blood? Where?"
Yao Jun shrugged his nostrils, but smelled nothing. The weather was too cold, and every breath felt like a knife cutting back and forth in his nasal cavity. If there was a smell of blood, it would be his own blood.
"Did the detector respond?"
Bifang adjusted the detector again, but there was no response.
Yao Jun touched his head in surprise: "No response, is there anyone nearby?"
"Maybe the detector was lost, or maybe the other party was not prepared, but I did smell blood, very strong."
"But I don't smell anything." Yao Jun sniffed vigorously, but still smelled nothing. "It's so cold, the blood must have frozen, so how can the smell come out? It must be a dog's nose?"
"Don't ask. If you ask, it's talent." Bifang didn't explain much. With a cautious attitude, he trotted over following the smell in the air.
When crossing a small slope, Bifang quickly retracted his right foot and stopped Yao Jun and Jarrett behind him.
"Be careful, there's a glacier."
As he spoke, he stretched out his trekking pole and poked the snow pile in front of him. With a weak force, the snow slope collapsed rapidly, splashing countless white smoke and dust. Under the sunlight, a bottomless deep blue glacier appeared in front of everyone.
The audience was stunned. Just looking at the snow slope in front of Bifang, they couldn't see any signs at all. If it was an ordinary person, wouldn't he be dead immediately after this step?
How the hell did Master Fang figure that out when there weren't any signs?
[Fuck, how did you find out? ]
[X-ray, Fang Shen used X-ray! ]
[What the hell is X-ray? Have I walked into the sci-fi channel? Is this the river? ]
[New fans may not know this, but Old Fang is our country's secret weapon. He has undergone a physical transformation, and his eyes can shoot x-rays, making him easy to see through. There is a verbal agreement within our army that if the enemy does not deploy nuclear weapons, we will not deploy Fang Shen! ]
[Can the matter of the ultimate weapon be concealed? ]
"You certainly can't tell just by looking at the pile of snow in front of you, but look at the bigger picture."
After hearing Bifang's words, the photographer far away in the base camp immediately flew the drone high up and took pictures of the hillside. With an infinitely wide field of vision and good lighting, everyone finally saw the difference.
On the snow slope, there is another scar-like snow line that is slightly raised, leaving some shadows under the sunlight. Although it is very shallow, it becomes conspicuous once the line of sight is broadened.
"Glaciers covered by snow are difficult to spot. Many people are buried by such glaciers every year. However, a wider field of vision can form a more comprehensive understanding. When you see such a streamlined snow line in front of you, you must be vigilant. In addition to the snow line, you can also judge by color."
Bifang grabbed a handful of snow from the edge of the crack, took a few steps back and put it on the ground.
The audience widened their eyes and after careful comparison, they slowly discovered that the snow at the edge of the crack seemed to be darker in color?
[The snow at the edge of the crack is darker ? Is this an illusion? ]
"It's not an illusion. We call these cracks in the glacier covered by snow dark cracks. In addition to being slightly lower than the surrounding area, you can observe the shadow lines from high altitude during the day. You can also distinguish them by the color of the snow. The color of the snow on the dark cracks will be slightly yellow or black."
"Is it so magical? What's the principle?" Yao Jun listened with great interest and grabbed a handful of snow and licked it.
Doesn't it feel like there's any difference?
Same ice teeth.
Bifang laughed: "Guess?"
"If I had known that, I wouldn't have followed you around."
"It's the specific heat capacity." Bifang patted the snow in his hand. "There is no air flowing under the cracks. The specific heat capacity is greater than that of rocks. The temperature difference causes the crystallinity and density of the snow to be different. The refractive index changes, and the color becomes darker."
what?
The audience was stunned.
[I have thought that Bifang knows a lot, but I didn't expect that I still underestimated him. ]
[Specific heat capacity, damn, I can't figure out the reason for it in my lifetime. ]
[Is this the boss? Trembling]
Bifang walked along the cracks in the glacier, trying to find if there were any aluminum ladders left by the Sherpas.
"Generally, the depth of a glacier crack is 25-30 meters. This is obviously deeper. The ice layer above this depth is relatively solid. The deeper you go, the ice crystals will become larger and the adhesion will become stronger. When subjected to pressure trying to separate it, its internal structure will become more compact due to the pressure, and its appearance will look like thick cream or syrup."
"In fact, the best way to cross the glacier is to go around it. It is much safer to go around it than to cross it. The second best option is to choose a snow bridge. The deep snow in winter will become hard under the strong wind, and it is possible to form a snow bridge on the ice crack, which will not melt until summer. There is also a more solid snow bridge, but it is no longer a snow bridge. It is a thin isthmus connecting two ice cracks."
What is the Isthmus ?
[It is a narrow land connecting two continents, such as the Isthmus of Panama between South America and North America. That is a typical isthmus, but isthmuses connecting ice cracks are relatively rare, at least I have not seen them very often.]
[Brother Bullfrog, what do you do? ]
[A geologist, my colleague told me this morning that a talented person live-streamed an avalanche and performed a textbook self-rescue. I was curious and came to see it. The host was really amazing. Although I didn’t watch it for long, he was very professional. I didn’t know some of the knowledge.]
Old Deng stroked his glasses and typed this sentence on the computer.
The snow on the dark cracks of the glacier is darker in color because of the specific heat capacity. Although he has only been working for a short time and his main focus is not glaciers, he knows more about it than ordinary people. This knowledge really opens his eyes and he has the urge to fly to Mount Everest right now to study the glaciers.
"This kind of phenomenon cannot be discovered through simple research and investigation, but requires a lot of experience accumulation. Where did this guy come from?"
[There are all kinds of people watching the live broadcast. Yesterday a big hacker showed up, and today a geologist showed up.]
[Didn’t we have biology and history professors in the past? (dog head)]
【“Prosperous!” 】
Unfortunately, Bifang did not find the aluminum bridge left by the Sherpas, but only found the nail holes left next to the glacier. The aluminum bridge should have been washed away by the avalanche last night.
But fortunately, Bifang found a snow bridge.
It is very wide and thick, and looks like a road.
"When you encounter a snow bridge, you must carefully observe it from the side before stepping on it. The pit must not be too thin, and then try to walk up to detect it on the spot. Be careful. A team member should have a team member on the side to ensure the posture and tighten the rope to prevent the snow bridge from suddenly breaking and falling into the crack. After the first team member passes, the other team members can strictly follow the leader's steps after another team member tightens the rope to ensure it."
"The strength of a snow bridge is mainly affected by temperature. In cold winter or early morning, a snow bridge may be strong enough to support a truck, but after the snow melts in the afternoon, it may not even be able to support its own weight. Every time you cross a snow bridge, you must be vigilant. If you pass it safely in the morning, it does not mean that you can pass it safely in the afternoon."
"Tighten it." Bifang turned to Yao Jun and Jarrett and said.
The two nodded, lowered their center of gravity at the same time, and embedded their crampons firmly into the ice.
Bifang took a deep breath and was about to step out when a bloody hand pressed on the ice at the edge of the glacier a few meters away. The blood quickly coagulated into a bloody handprint and grew sharp ice crystals.
Bifang's pupils suddenly contracted.
"Go and save them!"
