According to the Jones brothers, the cold wave that came a few days ago was both normal and abnormal.
In Montana, the first cold wave arrives in late October every year, so this cold wave is basically a normal situation. But this cold wave is too strong, almost a strong cold wave that occurs once in decades, so this cold wave is not a normal situation.
But it's not November yet, and to use the old Chinese saying, it's not really cold yet. So, four days after the cold wave, the temperature here has gradually started to rise.
But even if the temperature rises again, the highest temperature here is still below zero degrees, and the temperature at night is still around minus 15 or 16 degrees, so the surface of the Missouri River is frozen solid.
Yang Jing stood on the shore and was not in a hurry to get on the ice. He did not know the conditions of the ice. If he went on rashly, if the ice was not thick enough, he would be the one in trouble.
But this was not difficult for Yang Jing. He had learned how to judge the thickness of the ice when he was a child playing with his uncle. It was very simple. He just needed to find a stone weighing about one pound and throw it high up. When the stone landed on the ice, he could judge whether the ice could support a person by listening to the sound.
If the sound made by the stone falling on the ice is a dull sound, it means that the ice is either not frozen solid or is too thin to support a person.
But if the sound is very clear and has a long echo, then there will be absolutely no problem for people to walk on such ice.
After the stone fell on the ice, it not only created a small white spot on the surface, but also emitted a series of crisp echoes. It was obvious that at least this section of the river's ice had been completely frozen into a single piece, otherwise the ice would not have emitted such crisp echoes.
In fact, there is another way to judge the strength of the ice layer, which is to look at the color of the ice layer.
Generally speaking, the bluer the ice is, the stronger it is, and the lighter the color is, the weaker the ice is.
Another way is that when the temperature drops rapidly, the river or lake freezes quickly and then the temperature continues for several days, the strength of the ice layer formed at this time is the greatest. As time goes by, if the temperature does not continue to drop, the strength of the ice layer will become lower and lower.
The ice on the river where Yang Jing is now is covered with a layer of frozen snow, forming the so-called "snow ice", but by listening to the sound Yang Jing can clearly judge that there is absolutely no problem for people to be on the ice here.
Sure enough, when he stepped on the ice, he stepped on the ice with a little force, and the feeling transmitted from the soles of his feet was as if he was stepping on concrete.
Then he used his boots to wipe away the snow on the surface of the ice, and the slightly bluish ice underneath was immediately revealed.
The color of the ice immediately made Yang Jing feel confident and bold as he walked straight to the center of the river, then found a random place to stop the cart.
Taking the steel drill from the car, Yang Jing used all his strength to hammer it down. Although Yang Jing did not use the Feedback skill, he still had a lot of strength, but the steel drill only made a small white hole on the ice, and it also hurt his hand.
"Damn! This ice is really solid!" Yang Jing muttered with satisfaction, raised the steel drill high, and then activated the feedback skill. The next moment, the steel drill was inserted deeply into the ice.
This happened two or three times, and Yang Jing suddenly felt his hand lighten, and he knew he had broken through the ice.
He repeated this operation N times on the ice, and a circle of ice eyes formed with a diameter of about one meter. Then Yang Jing picked up a sledgehammer and smashed it hard in the center of the circle. With only two hits, a piece of ice with a diameter of about one meter was smashed down.
Yang Jing picked up the hook and dragged the ice directly onto the ice surface. Only then did he discover that the thickness of the ice here was more than ten centimeters.
Judging from the thickness and strength of the ice, it would be no problem for a person to ride on it, even a snowmobile would be able to get on it!
What surprised Yang Jing was that as soon as he dragged the ice onto the ice layer, water began to splash out of the hole in the ice, and a big fish more than half a meter long suddenly jumped out of the hole in the ice...
"Damn! This fish is fierce!" Yang Jing cursed with a smile. Although he often followed his uncle to break ice to fish when he was a child, he had never seen a fish jump out of an ice hole by itself.
The fish definitely did this due to lack of oxygen, but I'm afraid the fish didn't expect that this jump would directly determine its life or death.
The fish was struggling desperately on the ice with its body steaming, obviously trying to struggle back into the water. But who could blame it for its previous jump being so coquettish? Why would a fish have to jump so far like a kangaroo? It can't go back now, right?
What surprised Yang Jing was that this was actually a really big carp!
"Could it be that the Asian carp have invaded here?" Yang Jing also shook his head secretly. Before, he only knew that the Asian carp had invaded the Great Lakes, but he never thought that the Asian carp could swim upstream along the Missouri River and directly invade the upper reaches of the Missouri River. You know, there are several large hydroelectric power stations along the way. How did these Asian carp cross the dams of the hydroelectric power stations and come here?
"Tsk tsk, this carp has become a spirit!" Yang Jing muttered as he picked up the net and scooped up the carp that was gradually becoming motionless.
