But a straight tree stick was definitely a surprise to Bifang. A pathfinder stick in the snow was of great help.
Protect joints, maintain balance, save effort when walking uphill, and effectively increase average speed.
Studies have shown that a long pole of appropriate length can reduce the impact force on the knee joint by more than 40%, especially when going downhill.
With Bi Fang's joint strength, he is naturally not afraid of impact, but it can help maintain balance and increase forward speed, which is really good.
In particular, the tree stick itself is not so dry that it will break when broken. On the contrary, it still retains a considerable degree of toughness and can be used as a pathfinding stick.
And with its original length, it can barely be used as a long weapon.
The reason why it is reluctant is because the Arctic is indeed too dry. Although the tree sticks still retain their toughness, they are still somewhat suitable for use as spears.
As for stirring weeds to scare away snakes, and removing thorny vines and spider webs on the road, they are useless in the Arctic.
There were no trees nearby. It was obviously broken from a tree and blown here by the wind. There were still many branches on it.
Bi Fang selected a section with the indicated length and straightness, and cut off all the excess parts with a knife. The larger branches were collected and used to weave snowshoes. The smaller ones, which were useless, could also be used as fuel.
Nothing is wasted.
"This is not the first time I have made snowshoes. Sometimes, in difficult environments with steep terrain and white snow, you will find that your boots always get stuck in the snow. In this case, snowshoes are
It seems very necessary.”
"Getting stuck in the snow is like getting stuck in the mud when planting rice in the South. Walking will consume more energy. Energy is precious and we must save it. Homemade snowshoes can spread your weight over a large area.
, it will be easier to walk on the snow."
"This branch is a pine tree, which is also the most common tree in the polar regions. Although it has no leaves, the branches are dense and it is a good material."
Bi Fang cut off 5 to 10 large branches about half a meter long and tied the bottoms of the branches together. The branches were gathered together loosely along a midpoint. Next, he tied his feet with a strap.
The branch is on the front 1/3 of the snowshoe.
"If you have enough time, you can use saplings and string to make a more complicated trail snowshoe, but we don't have this need, Greenland is still quite wide."
Greenland is essentially a region made up of towering mountains, huge blue-green icebergs, magnificent fjords and barren exposed rock.
But from the air, it looks like a vast and empty wilderness, with jagged black peaks everywhere, occasionally penetrating the dazzling white ice fields that extend infinitely.
Greenland is a very different island as a whole: in summer, purple saxifrage and yellow poppies bloom in the meadows near the coast, as well as shrubby mountain ash and birch trees.
However, the central and northern parts of Greenland are enclosed on a huge ice sheet. Neither a piece of grass nor a small flower can be found within hundreds of kilometers. It is quite vast and wide and looks like a white desert.
"If you are not going to wear snowshoes to walk on flat ground, but to go up a mountain, down a mountain or across a hillside, then you need the snowshoes to have certain ground adhesion properties. Therefore, the toes, heels and
There should be cleats, hooks and the like on both sides to keep your snowshoes attached to the ground."
Briefly introduce other situations and move on.
With the help of snowshoes, Bifang's walking speed has obviously increased to a higher level.
I looked at the sun above my head. Today's weather is quite good. The sun is very bright. The surface of the snow has melted and frozen, making it rustle when you step on it.
Not only that, in autumn and winter, extratropical cyclones often invade Greenland, causing the temperature in Greenland to change drastically, sometimes -50°C, sometimes -30°C.
Bi Fang suspected that today's temperature might be only over 20 degrees below zero, which was far less scorching than the previous few days.
The howling wind is like ice knives, trying to kill people. Maybe the meat cut off is better than the hot and fresh sea bream from Beichen Tianlang's blade.
Unrealistic fantasies were roaming in his mind. Bi Fang felt that he might be too hungry, and his thoughts began to wander.
Under normal circumstances, I am a very purposeful person. Only in this way can I gradually establish stable living conditions in the wilderness, but I will not have random thoughts and sticks here and there.
Bi Fang felt that this was caused by a lack of energy in his brain, and his willpower was constantly being worn away in this harsh environment.
More people think that willpower is a psychological topic, but they don’t know that it should actually be classified as a physiological topic.
This thing is a consumable product. Every time it confronts instinct, it is internally consumed, and it is also the main factor supporting efficient work.
When the willpower is not enough, it is easy to fantasize, that is, to wander away.
"call!"
Bifang opened the ramen noodles that covered his mouth and nose, exposed his face to the cold wind, rubbed it, took a deep breath, and tried to increase the blood oxygen level as much as possible, only then did he feel revitalized.
It's time to quicken the pace.
The unprecedented hunger allowed Bifang to unleash his potential. With the help of snowshoes, he even ran faster than when he first arrived in Greenland.
Bi Fang squatted down, smashed a rounded light blue ice cube, and stuffed it into a dry kettle.
"The older the sea ice is, the less salt there will be in the ice. When old sea ice is broken, the edges and corners are rounded, and the surface is often pitted. Its underwater part will appear light blue. Fresh sea ice is
It is milky white like milk and has an angular shape after being broken into pieces."
【What is the truth?】
"It's because of the different microstructures, which are different from ice to ice."
Bi Fang pointed to the ice at his feet, beside which was the thick snow that had been dug up and piled up.
After a snowstorm, there is almost no ice exposed on the surface, and you have to shovel snow to get water.
“The sea ice initially formed by primary ice is all tiny ice crystals in the shape of needles or flakes; a large number of ice crystals condense and aggregate to form sticky or spongy ice. When snow falls on the sea surface where the temperature is close to freezing point, it can directly form sticky ice without melting.
ice."
"Ice skin is a layer of sea surface ice formed by direct freezing of calm sea surface, or by continued freezing of primary ice. Its thickness is about 5 centimeters, relatively brittle, and easily broken by sea surface wind or sea surface current.
Turn into rectangular thin ice cubes.”
"If the primary ice continues to grow and freezes into a thin elastic ice layer with a thickness of about 10cm, it will be easily bent and broken into rectangular ice cubes under the action of external force. The thin ice flakes broken into cake-shaped ice will be easily broken under the action of external force.
The bottoms will collide and squeeze each other, and the edges will rise."
"It eventually formed into a circular ice disk with a diameter of 30cm to 3m and a thickness of about 10cm. Ice of this level is old ice, and new ice will not freeze like this. It seems that the river section under our feet has been frozen for a long time.
Already."
The water friends were still listening to Bifang's popular science, but when they heard the last sentence, they were stunned for a moment, and finally reacted suddenly.
