"Phew, I'm glad I showed you a look, otherwise something would have happened."

The camera director wiped the sweat off his forehead and took a long breath, fortunately the guy didn't eat it, otherwise there would have been a live broadcast accident.

Just now, the program team confirmed that the mushroom that the contestants wanted to swallow was the Angel of Death mushroom, and in an instant, everyone was convinced by Bi Fang.

Just by looking at it, you can instantly identify the easily confused poisonous mushroom, which is not everyone's ability.

What a reassuring advisor!

The Eliminator had nothing to say, and let the helicopter send him out of the Rocky Mountains,

"It's my job." Bi Fang waved his hand, indicating that it was not worth mentioning, and as a security consultant, he had the responsibility to avoid danger.

A false alarm.

The monitoring team is more attentive to the contestants, and strictly guards against it, for fear that they will swallow some strange things again.

[I'm dripping, I can't eat this thing, I feel more dangerous. 】

[Finch, fortunately there is an old party, otherwise wouldn't you burp a fart? ] 】

[But will mushrooms grow in this kind of weather?] 】

"Yes, a lot of mushrooms grow in winter, but I was a little surprised that the Angel of Death mushroom would appear." The audience's questions gave Bi Fang a wake-up call.

It stands to reason that the Angel of Death mushroom should not appear until around April, and it is not impossible for the mushroom to grow a month earlier, but is the temperature so high in these two days?

Bi Fang glanced at the thermometer and found that the temperature had actually reached about ten degrees.

Two nights ago, it was still below freezing!

Even if the temperature warms up during the day, five or six degrees is about the same, and it actually reaches ten degrees Celsius!

"Foehn?"

Rubbing his chin, Bi Fang faintly guessed that the Rocky Mountains were close to a cold snap, and there should not be such temperatures in late February and early March, and the only explanation was that there was a foehn!

Pang Di heard Bi Fang's muttering and asked curiously, "Foehn wind, what is that?" ”

"A strange weather phenomenon in the Rocky Mountains of North America."

Seeing someone asking, Bi Fang also explained to the audience who heard it.

The Rocky Mountains were formed by the strong collision and extrusion between the American and Pacific plates, trending northwest and southeast, and trending roughly parallel to the western coastline of North America.

The area selected for the competition is located north of 50°N, which is controlled by the prevailing westerly wind belt from the perspective of the barometric wind belt.

In the winter season, it is more affected by the cold air of the Arctic Ocean, and the temperature is low and snowy.

At the end of winter, as the climate warms up, the high pressure over the North American continent will begin to weaken, and the cold air from the Arctic Ocean will gradually weaken, and the prevailing westerly wind belt from the Pacific Ocean will begin to affect the region.

Due to the mountain blockage, the warm and humid westerly winds are strongly lifted by the terrain to form abundant topographic rain, and after crossing the tall Rocky Mountains, on the east side of the Rocky Mountains, the air flow contains less water vapor and sinks down the slopes.

As the altitude decreases, the air temperature rises, and in the foothills, it becomes a dry and warm "foehn wind".

Foehn phenomena occur in many parts of the world, including in the Alps, the Greater Caucasus on the border between Asia and Europe, and the Andes in South America.

"If it's okay to bring water vapor, the evaporation of water will take away a lot of heat, but because of the mountain block, the water vapor is stopped, leaving only the hot and dry wind, and the temperature in the Rocky Mountains will rise very quickly during this time, like a huge fan blowing on the ground, and a large amount of snow formed by the cold air of the Arctic Ocean will melt quickly.

You see, there was a little snow on the ground two days ago, and today I can't see it anymore. ”

After hearing it, the program team immediately called up the images of the previous two days for comparison, and no one paid attention to it before, but now it looks like it's really the case.

The day before yesterday, the forest floor was covered with a layer of white snow, but now it has completely melted, revealing a bare black-brown soil, which may soon turn green.

It's melting too fast, isn't it?

In general, the thicker the snow, the longer it will take for the snow to melt in the spring.

Not to mention the wilderness, even in the city, it takes nearly a week to completely melt away from the occasional heavy snowfall, but now this scene has happened in less than two days.

"Because of the foehn wind, as soon as a warm wind blows in spring, the snow that is more than 10 centimeters thick will melt quickly in a day. When the snow melts, the earth quickly rejuvenates, and many mushrooms grow early, this weather phenomenon helps local production, so the locals call this warm air flow "snow eaters". ”

[A good image of the name, snow eater, cowhide]

[No wonder the Angel of Death mushrooms have grown, and the mushrooms on our side will also be in April]

Many viewers said that it was an eye-opener, and there was this weather phenomenon that they had never heard of before.

However, Pang Di was a little puzzled, will the rapid warming of the climate caused by the foehn have any effect?

"When the temperature warms up, will the brown bear wake up early?"

"Hmmm......"

Bi Fang lowered his head and groaned, and nodded for a long time.

"I don't rule it out."

Audience: "! ”

Lack of food is the main reason for hibernation in animals, and many bears don't even hibernate if food is adequate.

"But the probability is still relatively small, survival in the wilderness is relatively dangerous, all kinds of dangers are objective, the contestants know in their hearts, do you have to give up recording because of this?"

Seeing Pang Di's worry, Bi Fang comforted a little.

In the previous life, it was impossible for those wilderness survival programs to give up recording because there were bears in the wild, so what did it mean?

What you want is a sense of realism, could it be that the places that Bei Ye went to were filmed only after the program team captured the bears, tigers and wolves?

It can't be.

That's because of choking.

Bi Fang patted Pang Di on the shoulder: "Okay, don't think about it so much, what we can do is to ensure the safety of the players as much as possible, let's go back to recording." ”

"Okay."

Pondy nodded, the words are all on the table, and it can only be so.

The competition among the competitors continues, and Bono, who started the first time, has even walked nearly 70 kilometers out of the drop-off point, far surpassing the other competitors.

Mugallen, who set off at the end, was also not to be outdone, after eating food, he was full of energy, he reached a speed of seven kilometers per hour, and made a little detour on the way, obviously discovering something.

The only two female contestants likewise made a discovery, a cave.

Ava excitedly stared at the cave not far away and waved at Lisa, "Hey, Lisa, come and see!" ”

"Caves?"

Lisa was a little surprised, and then excited.

For two days, they had not caught any prey at all except for eating some lichens and earthworms.

[Lunch has fallen? 】

What's in the cave? Python? 】

[Feels like a rat hole?] 】

[Fang Shen quickly say, what's in this? 】

The forest is rich in species, and there are many animals that can dig holes, but it is associated with endemic species, combined with the size of the cave entrance......

Bi Fang stared at the palm-wide cave for a while, and said suspiciously: "It looks a bit like a cave of grassland dogs and rats?" ”

Prairie dog?

What's that?

"It's a groundhog."

[Groundhog? I said it earlier, I'm familiar with this, ah!!! 】

[Damn!] There is a picture]

[That's it!] Groundhogs? 】

Bi Fang nodded and explained: "There are a lot of marmots in the Rocky Mountains, usually in the grasslands at relatively low altitudes, which coincides with the duo's route, and what they have to pass through is the forest and grassland. ”

"And marmots do not hibernate, are used to living in groups, are highly social animals, like daytime activities, and are good at digging burrows. If it's a marmot hole, it means there's a big herd of marmots, at least six or more! ”

Six!

The audience thought of the fat appearance of the marmot, and suddenly their breath stagnated.

You can eat it for a long time!

The duo didn't expect this, they didn't know what was in the cave yet, but they were still happy, just by looking at the size of the cave, they knew that the animals inside were not too small, at least enough for the two of them for a day.

Thinking of having something to eat, the two were full of energy, and after a brief discussion, they immediately divided up their work, Ava went to search for bushes and branches, and Lisa, who was a member of the berets, searched nearby for other holes.

Seeing Lisa plugging the newly discovered rat hole, Bi Fang couldn't help but nodded: "It's the right decision, many animals that are good at digging holes have multiple escape routes, if you only catch one hole, you may find nothing, you must search around for other holes and plug them all."

Groundhogs are experts in burrowing, they have a basically independent tunnel system, the deepest can dig up to 5 meters, the hole will be higher than the ground to prevent water, there will be a refuge room when the enemy appears, and then there will be a storage room, living room, toilet, etc., generally at the end of the tunnel there is a main nest with a soft straw mat, the infrastructure is quite perfect.

In addition, Ava is also particular about the branches she is looking for, and her purpose should be to burn the plants and smoke the animals in the cave out, so all she collects are fresh branches that have been broken off from the trees, which have a high moisture content and can produce more smoke when burned. ”

[Groundhog: shivering, the outside world is so scary]

[Grass and marmots are more comfortable than me!] 】

[Wori, this quality of life is higher than mine, I have been working for three years, and now I can't even afford a toilet, Mu]

Who isn't? 】

Hearing Bi Fang's introduction to the luxurious residence of the marmot, many people showed envious looks.

But the thought that they were about to be eaten made me feel inexplicably refreshed.

Bi Fang couldn't help but laugh and said: "Don't say that, although grassland dogs and rats are also rodents, they are natural fertilizers, they can continuously mow the grassland, so that the grassland can increase the protein content and the decomposition ability of the grass, which has a great effect on environmental protection." ”

As she spoke, Lisa had sealed all the holes she could find with stones, and Ava had rekindled the fire with the charcoal fire from yesterday.

After ten minutes, Ava lit the fire, and she put the branches and shrubs she had collected earlier into it, and the branches quickly twisted and deformed in the heat, creating a large amount of white mist.

Seeing this, Ava quickly stuffed the bush into the hole, took off her coat to block the fire, and muffled the white smoke in the hole.

The white smoke had no choice but to drift into the cave and quickly fill the entire crypt.

Lisa clenched the spear in her hand, and when the animal emerged from the hole, she stabbed it quickly.

Soon, there was a rustling sound in the cave, followed by a slightly piercing scream.

"It's coming!"

Lisa was so excited, there really was something in the hole!

It seems that there is more than one voice!
