Super Chief

In the winter of 1777, the stone bear did not go to Beijing, but appeared in the mountainous area about 900 kilometers west of Denver.

　　 It has gone deep into the Rocky Mountains. Although the latitude is much lower than the Great Lakes region, Shixiong feels that the winter here is more difficult than the winter in the Great Lakes region.

　　 Although the temperature of the Great Lakes in winter is low, it is not uncomfortable. But here is not enough. The temperature here in winter is not much higher than that of the Great Lakes. The most important thing is that the cold wind that prevails here every day blows like a knife on the face, which is really unbearable.

　　 The position where the stone bear is now has a very famous name in later generations-Salt Lake City.

That’s right, in the winter of this year, the reason why the stone bear can brave the biting cold wind and the heavy snow that can reach the thigh root is because of the copper mine appointed by the stone bear a few years ago. The production of copper ore has already begun. Well, copper ore alone is not enough to make Shixiong come here braving the cold winter. The most important reason is that not only has it begun to produce a large amount of copper ore, but the black corpses who undertake the main mining task are still mining copper ore At that time, a very rich silver-gold associated mineral vein was discovered...

　　Copper is a very important strategic metal material, and its use far exceeds that of precious metals such as gold and silver.

　　 But compared to copper, higher-value gold and silver are obviously more attractive. Even if Shixiong was already the highest leader of a huge tribe, when a rich gold mine appeared, he still couldn't bear his excitement and ran here to watch this copper and gold mine in person.

　　 In this large basin surrounded by several surrounding mountains, there are not only mountains, valleys, but also deserts and lakes. The location of this copper mine appointed by Shixiong is located between the largest salt lake in North America-the Great Salt Lake and Lake Utah.

　　 The Great Salt Lake is the largest saltwater lake in North America, and Utah Lake, which is only more than 50 kilometers from the southern end of the Great Salt Lake, is a freshwater lake.

　　Between these two lakes is Salt Lake City, the capital of Utah in the later United States.

　　Of course, in this era, there is no Utah, nor Salt Lake City. Here, it used to be only the area where the Hughini, Yuren, and Payut people lived. However, seven or eight years ago, this place was already in the pocket of the Cherokee tribe. The Husseunis, Yous, and Paiutes living here now have only one name-the Yanhuang tribe.

　　 To be fair, this is not a good residential area, the natural environment is a bit harsh, and the output is not very rich.

　　 The area of ​​the Great Salt Lake in the north was much larger than the Great Salt Lake in later generations. In this era, the area of ​​the Great Salt Lake exceeds 6,200 square kilometers, which is larger than Qinghai Lake in China.

　　 However, in the 20th century, the area of ​​the Great Salt Lake rapidly shrank to less than 4,000 square kilometers, and one third of the lake surface disappeared.

Although the Great Salt Lake is very large now, there are no other organisms in this huge inland saltwater lake except for some small shrimps and algae. The salt content of this lake is as high as 25%. The lake on this planet with salinity second only to the Dead Sea.

　　Under such high salinity, the buoyancy of the water of the Great Salt Lake is extremely high. Just like the Dead Sea, people cannot sink inside...

　　 guarding such a large lake without any aquatic products, coupled with the harsh natural environment here, so this is really not a good gathering place. Compared with the abundant natural resources of the Great Lakes region, the barren ones here can make people cry.

　　 But here is not nothing. Under the mountains, there are huge metal deposits, among which there is an amazing copper deposit with large reserves.

　　In later generations, there is a world's largest open-pit copper mine-Bingham Canyon Copper Mine.

　　 But a few years ago, apart from Stone Bear, no one in the world knew about the existence of Bingham Canyon Copper Mine.

　　 Now, the mountain range less than 100 kilometers long in front of Stone Bear is the Oker Mountain Range where the later Bingham Canyon copper mines are located.

　　In the early twentieth century, the Americans discovered an open-pit copper mine in the Bingham Canyon in the mountains near Salt Lake City, so the crazy Americans began to excavate for more than a hundred years.

　　 Shixiong once heard a story about excavator technology, it is definitely Da Lan Xiang top quack. Regardless of who digs the most pits on this planet, if the Americans claim to be second, absolutely no one dares to be the first.

　　 The source of this sentence is actually from the Bingham Canyon Copper Mine.

Since 1906 began to excavate this copper mine, the crazy Americans first dug a mountain several hundred meters high, but when the mountain was gone, the Americans discovered that it was still under the mountain. There are more copper mines. So the Americans continued to dig the pit frantically, and it took decades to dig out a huge pit 4 kilometers wide, 7.7 square kilometers in area, and 1,200 meters in depth!

　　 This pit is unique on earth, and no artificial pit can be as big as this pit.

　　 Later generations have calculated that, in terms of the width of this mine, if all were built into a stadium, then this stadium would be able to accommodate 9.5 million people!

In more than one hundred years, crazy Americans have dug up 5 billion tons of ore here, and extracted as many as 12 million tons of copper and thousands of tons of silver and silver from these ore. Hundreds of tons of gold!

　　 In this pit similar in shape to a square funnel, all walls are densely packed spiral mine tunnels. The mine carts at the bottom of the pit pull the ore along the spiraling tunnel to the outside of the mine.

　　 And if these spiral mine tunnels are straightened, the length will reach 800 kilometers!

　　 In short, in Shixiong’s previous life, this huge mine that has been dug for more than a hundred years but is still digging is a miraculous existence.

It’s just that now ~www.readwn.com~ is still a big mountain, but in a corner of this big mountain, a small gap has begun to appear, which is hardly dug out by thousands of black pterygium miners in the past few years. .

　　 Well, it is worth mentioning that in addition to the black corpses who escaped, there are more than a thousand Iroquois secretly sent here by the rabbit mouth.

　　 These thousand one hundred and eighty-nine Iroquois are the people who take care of the seven Iroquois tribes of Wakaya and them, as well as the immediate relatives of the six chiefs of the Iroquois Alliance.

　　 The evil that the Iroquois committed against Wakaya, who was guarding the ancestral land, made Stone Bear very upset, so Rabbit Mouth took revenge on these people. Except for more than forty children who were given away to others, the other culprits were all brought here by the rabbit mouth to mine.

　　 This copper ore bear still continues the name of the previous life-Bingham Canyon Copper Mine.

　　 It's just that now this copper mine is not only countless times smaller, but very few people in the entire tribe know about this copper mine. The people who mine here are all black corpses, and the guards are the elite fighters of the Grim Bear Army.
