On the ground, there are some irregular ice picks, and smoke rises from them.

"Geographically, it's called the Erebus Ice Tower, and it's a unique sight in the world. ”

"Forever ago, the ice above the earth cracked and cracked, and the volcanic water vapor continued to rise, condensed into water in the ice cracks, and then froze into ice, and then for endless years, the water vapor continued to condense, and the ice towers continued to grow taller, and finally formed such a spectacle, in the world, only here can you see hollow ice towers, which look like chimney hot pots. ”

"My gun brother does not leave the line in three sentences. ”

Professor Wang looked at the ice towers on the ice cap: "These ice towers are inaccessible, we have to enter through the ice cave crack, and we may have to judge where to enter and go further." ”

Fang Hong shrugged: "This is the job of you professionals, I can only be responsible for taking you down." ”

"No problem. ”

The expedition team had to leave two people on the ice, and the other five had to go down.

It wasn't long before the most famous ice crack of Mount Erebus was found.

Professor Wang sighed: "In the past, when we came here for inspection, there was always a lack of professionals to lead the way, but now no matter what we do, we can find top players in China." ”

Fang Hong smiled awkwardly: "I'm not a good hand either......"

At the crack in the ice, the ice sheet becomes no longer smooth, but almost steeply and vertically downward, about twenty meters above the ground, with a steep slope of the slanted ice downward.

Fang Hong found a place on the ice sheet and drove the expansion nail, and then poured the water on it, and the water began to freeze when it landed, and it was already frozen with the ice sheet after a while.

Fang Hong made two buckles back and forth, and buckled two ropes: "Now my country's scientific expedition in Antarctica is at the forefront of the world, two years ago we drilled from Ice Dome A to record the Antarctic millions of years of climate change icicles, these icicles not only help us understand the climate change of Antarctica, but also can infer the climate change of the entire earth over the years, and even the distribution of volcanic ash can be inferred that those volcanoes erupted in those specific years, which can be accurate to the climate change on the earth in years." Of course, this information is top secret. ”

It's actually very simple, the icicles drilled are snow at the top, then the white opaque ice formed by the snow compacted, and then there may be melting ice from climate warming, global volcanic ash deposits from massive volcanic eruptions, and so on, all the way to the bottom of the primordial ice.

Theoretically, Antarctica records the climate change of every year from the ice age to the present.

Fang Hong found his way down the ice slope: "In a certain eruption of Mount Erebus, the magma melted the snow, and in an instant, the snow turned into spring water, and the water flowed downward, from here into the ice crack, and then was quickly frozen, and finally formed a hard ice layer that could not even be blown away by a bomb, and it was also a road down to the ground. ”

Of course, Fang Hong himself can use the downhill rope to drag the cool and dazzling downhill, but considering that Professor Wang and the others have not used downhill equipment in the natural environment, they are also a little old. So Fang Hong has been looking for a place where it is easier to get down.

Although the ice slope is almost vertical, but due to its weird and changeable shape, there are still a lot of gentle slopes and bumps that can be stepped on, Fang Hong tried it once, until he went down to the ground, and felt that Professor Wang and a few people should be able to come down on this road, so he shouted: "Buckle the rope buckle and slide down slowly, if you feel that there is no place to step on it, let go of the switch and use the rope to get stuck in the air and stay for a while, slow down, not too fast." ”

The first one is Professor Wang, on the one hand, to play an exemplary role, on the other hand, if there is any problem with the rope equipment, leave a few middle-aged people above, and also have the strength to rescue.

Professor Wang was almost under the ice with his butt against him.

Fang Hong is still in shape: "Don't lean your back against the ice, be careful if you are too fast and hurt your spine by the ice." ”

In a minute, Professor Wang went down to the ground and trampled on the ground, Professor Wang smiled: "Now we are in the cave under the ice sheet and between the ground.

There are very few ice caves in the world, except here, only Iceland has them.

However, Iceland's ice caves are nowhere near as large as here.

The experts came down one by one, and Fang Hong stood under the icefall to pick them up one by one.

"It's really rare to see the ground in the interior of Antarctica. ”

"I don't know why, but it always reminds me of combustible ice – the black chimney environment. At the bottom of the sea, the biosphere near the combustible ice is all dependent on the heat of the combustible ice to survive, and every living thing is nearly transparent and does not need sunlight to survive. Here, the heat of the underground lava should have the same function, not necessarily, and in the long evolution of organisms, there will also be a small biosphere that does not need the sun. ”

Just as the team was about to move forward, Professor Wang's radio rang out: "Professor Wang." ”

"Zhao Shu, is there a situation above?"

"Just now the Americans came over and invited us to spend the night at their little station. ”

Professor Wang thought for a moment: "I don't know if our expedition can end today, and if it does, we will return to the ship." If it's not over, you can go to their research station. ”

Fang Hong explained on the side: "We went up the mountain from the other direction, and there is a small scientific research station at the southwest foot of the mountain, the McMurdo Station, which is used by the Americans to monitor the activity of Mount Erebus, and there are people stationed in the summer. ”

"Americans are such dicks, they stick in everything. ”

Fang Hong was helpless: "Australia is a pro-American country, and it is very convenient for US planes to come from Australia, unlike us, we don't borrow Australian airports very much." Of course, there are times when I borrow it, but not so often. ”

After all, Australia is a Commonwealth country, and the Commonwealth countries have been transformed into the United States in modern times, but they are not very close to the Netland mainland. In the past 200 years, whenever the United States has participated in wars, Australia has taken the initiative to participate in the war, presumably to show its presence.

The so-called three island chains, Australia is also a link.

Finally, I had the time to take a closer look at the entire cave under the ice.

The distance between the ice cave and the ground is significant.

In the current visual range, the lowest place is about four meters above the ground, and the highest place is definitely more than fifteen meters.

In other words, the upper layer of ice at such a high position is very thin, and if you drive by, it is easy to fall directly and break your bones.

On the ice cave, there are also some icicles that resemble stalactites.

"Volcanic steam and hot gases emerge from the fissures of the ground, causing the ice to melt, and the melted water droplets flow down the lower levels and condense at the lowest places, so these icicles produce much faster than stalactites. ”

Next to him, climatology and aerologist Hua Bai looked at the instrument in his hand: "There is no toxic gas leakage, we can probe some distance deeper." ”

Professor Wang: "Let's go. ”

Fang Hong consciously walked in the front, he came to do this.

The overhead ice is weak in some places, and the sunlight that shines through the ice makes the ice look light blue, and the sunlight through the ice also gives the cave light.

However, more places were dark, Fang Hong turned on the headlamp and searchlight: "Everyone be careful, after all, I haven't been to this place before." ”

Walking in a dark place, the white is water, because the water is reflective, and the black is the ground, because the surroundings are black, if you can see with the naked eye that it is dirt or stones, then it must be convex, otherwise it will not reflect the light.

But under the powerful searchlight, the cave suddenly lit up.

Especially when walking into the huge hollow under the high ice, it gives a fantastic feeling.

Fang Hong sighed: "If there really are underground elves or underground worlds in the world, then it must be such a place. ”
