Yellowstone National Park is located in the Rocky Mountains, known as the backbone of the Americas. It is located in the northwest corner of Wyoming in the midwestern United States and extends northwest to Idaho and Montana. It covers an area of ​​9,000 square kilometers and is more than 100 square kilometers.

Some states in the United States are even larger.

About 96% of the land area of ​​Yellowstone National Park is located in Wyoming. Another 3% is in Montana, and the remaining 1% is in Idaho. Yellowstone Park is hundreds of kilometers from north to south, and from west to

Ninety kilometers to the east, rivers and lakes account for 5% of the land area. The largest water body, Huangshi Lake, covers an area of ​​more than 35,000 hectares. Huangshi Lake is about 123 meters deep and nearly 200 kilometers long.

On the lake shoreline, Yellowstone Lake, with an altitude of 2,200 to 300 meters, is the largest high-altitude lake in North America. Forests account for 80% of the land area of ​​Yellowstone Park, and most of the rest is grassland.

Yellowstone Park is located on a lava plateau between the Northern Rockies and the Central Rockies in the western United States. The North American Continental Divide flows diagonally along the southwest side of Yellowstone Park. This divide is a topographic feature that separates the Pacific and Atlantic water basins. Yellowstone Park's

One-third of the area is located in the western part of the watershed. The sources of the Yellowstone River and the Snake River are very close to each other, but on both sides of the watershed. Therefore, the water of the Snake River flows to the Pacific Ocean, while the water of the Yellowstone River flows to the Atlantic Ocean through the Gulf of Mexico.

.

Yellowstone Park is at the northeast end of the Snake River Plain. The Snake River Plain is a huge U-arc. The mountains extend out from the Boise Mountains in Idaho about six to seven hundred kilometers to the west. This terrain traces back

To the route of the North American Plate over the past billion years, as the North American Plate was transported by plate tectonics across a stagnant mantle hot spot, the terrain of today's Yellowstone National Park is the most recent manifestation of this hot spot in the Earth's crust.

Yellowstone Park is located on the Yellowstone Plateau with an average altitude of 2,340 meters. The Yellowstone Plateau is bordered on almost all sides by the Central Rocky Mountains with altitudes ranging from 2,700 meters to 3,400 meters. The highest point of the park is the Eagle Peak Peak, which is as high as

It is 3,500 meters high. The lowest point is along Rees Creek, which is only more than 1,500 meters. The most famous peak on the Yellowstone Plateau is Mount Washburn, which is 3,100 meters high.

Yellowstone National Park has one of the largest petrified forests in the world. Long ago, trees were buried by volcanic ash and soil. The buried wood was then transformed into mineral substances, commonly known as coal. These volcanic ash and other volcanic debris are thought to come from Yellowstone.

The park is local. This is mainly because Yellowstone Park is indeed a huge caldera of a super volcano. There are nearly 300 waterfalls at least five meters high in Yellowstone Park. The highest waterfall is a hundred meters high on the lower reaches of the Yellowstone River.

Yellowstone Falls.

There are three deep canyons in Yellowstone Park. They are slanted through the volcanic tuffs of the Yellowstone Plateau by rivers that have lasted for millions of years. The Lewis River flows south through Lewis Canyon, and the Yellowstone River flows northward.

There are two colorful canyons: the Grand Canyon of Yellowstone and the Black Canyon of Yellowstone.

The natural landscape of the park is rich and diverse. The highest peak in the park is Eagle Peak, with an altitude of 3,500 meters. The largest lake in Yellowstone Park is Yellowstone Lake, and the largest river is Yellowstone River. In addition, there are canyons, waterfalls,

Hot springs and geysers, etc., Yellowstone Park is proudly called "the most unique magical paradise on earth" by Americans. The park has convenient transportation and a 600-kilometer ring road that connects the main attractions of each scenic spot.

The route is 1,600 kilometers long.

The caldera in Yellowstone Park is the largest volcanic system in North America. It is called a "supervolcano" because the caldera was formed by a huge explosive eruption. The current caldera is the result of a catastrophic eruption that occurred 640,000 years ago.

Formed by an eruption, the eruption released a thousand cubic kilometers of volcanic ash, rock and pyroclastic material, creating a crater nearly one kilometer deep and eighty by fifty kilometers wide, and deposited lava stream tuff, which eventually

A violent volcanic eruption occurred more than two million years ago. That eruption ejected 2,500 cubic kilometers of volcanic material, creating a rock formation known as the Black Mountain Tuff and forming the Island Park caldera.

Tens of thousands of years ago, a smaller eruption ejected 300 cubic kilometers of volcanic material, forming Henry's Forked Caldera and depositing the Mesa Falls Tuff.

Sixty-seven million years ago, the Yellowstone caldera was almost filled with periodic eruptions of rhyolite lava. Rhyolite lava such as this can be seen in the basalt lava seen at Obsidian Cliffs and Sheepeater Cliffs. The lava formation is Yellowstone

The most easily visible rock in the park's Grand Canyon, where the Yellowstone River continues to carve these ancient lava flows, the Grand Canyon is a classic V-shaped valley, indicating channel-type erosion rather than glacier-induced erosion.

Yellowstone Park contains the world's most active geyser, the Steamboat Geyser in the Norris Geyser Basin. There are 300 geysers in Yellowstone Park, and in total there are at least 10,000 geothermal geysers, half of the geothermal geysers and one-third of the world's geothermal geysers.

Two of the geysers are concentrated in Yellowstone National Park.

In the past twenty years, the geological activities in Yellowstone Park have become more and more active. No one knows when it will erupt. And once it erupts, it will cause a worldwide danger, even in China on the other side of the ocean. Mainly

When the volcano in Yellowstone Park erupts, the volcanic ash ejected will directly reach the stratosphere, and then fill the entire earth, causing the earth to briefly enter winter. And no one knows whether this cold winter will last for a few years or decades. You need to know

When an asteroid hit the earth, it caused hundreds of years of cold winter, which caused great losses to animals and plants around the world. It was also the famous fifth mass extinction of organisms, and the famous dinosaurs disappeared at that time.

Yellowstone experiences thousands of small earthquakes every year, and there have been six earthquakes of at least magnitude 6 or above in recorded history, including a 1959 magnitude 7.5 earthquake that struck just outside Yellowstone's northwest boundary.

It is precisely because of so many earthquakes that all scientists are worried, because geological activities are becoming more frequent, which is not a good thing.

The Yellowstone region is the best megafauna wildlife habitat in the 48 contiguous states of the United States. There are approximately 70 mammal species in Yellowstone Park, including gray wolves, threatened lynxes, grizzly bears, and other large mammals.

Including American bison, American black bear, elk, moose, mule deer, white-tailed deer, mountain goats, pronghorn antelope, bighorn sheep and mountain lions.

The Yellowstone Park bison herd is the largest public American bison herd in the United States. The bison once numbered between 30 million and 60 million in North America, and Yellowstone Park is still one of their last strongholds. The bison herd in Yellowstone Park has ranged from

There were less than 50 bison more than 100 years ago and now there are 5,000 bison. The Yellowstone Park bison herd is considered to be one of the only four free-roaming and genetically pure herds in North America.

More than 80% of the total area of ​​Yellowstone Park is covered with forests. Most of the trees are American lodgepole pine, which is a tree with extremely strong vitality. The biggest disaster for plants growing in Yellowstone Park is forest fires. It is precisely because

Wildfires are raging, and many tree species are becoming more and more sparsely distributed, but the black pine has not only survived with its tenacious vitality, but also expanded its territory year by year. This is because the bark of the black pine is very thin and brittle, and

It is easy to burn, so once a fire breaks out, it is as difficult to escape as other trees, but it stores its seeds in strong and tightly closed pine cones. These pine cones can preserve the seeds for more than ten years. The American lodgepole pine grows very densely.

, just like the sugar cane forest, the diameter of the black pine can reach two meters, the tree height is thirty to forty meters, and the average age of the tree is one hundred and eighty years. Due to the lack of sunlight, the lower branches die and fall as soon as they grow.

Gentian pine is another widely distributed tree species. This tree also has strong adaptability and grows very fast. It can grow in a variety of climate and soil conditions. It is most dangerous in areas where wildfires often occur.

On the mountain slopes, they are also diverse and lush. In the Rocky Mountains, thousands of square kilometers of gentian pines are engulfed by fires almost every summer. However, "wildfires cannot burn them all, but spring breezes regenerate them." New life

Rise quickly from the ashes.

Two trees, American spruce and subalpine silver fir, are widely distributed in the western United States, climbing every mountain. However, these two trees have a common weakness. They are both very afraid of wildfires because their bark is very

Thin, and the seeds are sown as soon as they mature every year, so once a fire breaks out, both the trees and their seeds will be mercilessly devoured. For this reason, they are quickly driven out of the areas where wildfires are raging. Now

People often only see them on higher mountain peaks or in humid places, where they are most vulnerable to fire.

There are more than 1,800 species of trees and other vascular plants in Yellowstone Park, and about 170 species are considered alien species, among which 8 species of coniferous plants have been recorded. More than 80% of all forest areas are black pine forests.

, other coniferous forests such as alpine fir, Engelmann spruce, Rocky Mountain Douglas fir, and whitebark pine are found in scattered groves throughout the park.

When Tang Zhengqing was introducing Yellowstone Park to his family, he saw a herd of cows coming from a distance, "Xiaoqing, cow, cow!" Li Chunying also saw the herd of cows. After all, there were dozens of them, and the size was still the same.

It's so big that even a non-blind person can see it.

"Mom, that is the North American bison. It is wild and a protected animal, but you cannot use their brains. Of course, if you want to taste the bison, I will get one for you to try someday."

Tang Zhengqing thought his mother was interested in bison, so he said quickly.

"You kid, am I that kind of person? I'm not a glutton. I eat everything. When I was in China, I would sometimes hunt protected animals in the mountains and release them. We were short of food at that time.

, but we don’t eat everything, I still have this bottom line." Li Chunying said to Tang Zhengqing dissatisfied.

Tang Zhengqing did not speak, and could only smile. This was indeed the case. When he was in Qingyun Village, the old man would say that when hunting animals, try to hunt some common ones, such as pheasants, hares, wild sheep, wild boars, etc.

, after all, these animals have strong survival ability, strong reproductive ability, and they can still eat. This advantage is not comparable to other animals.

And there are many rules. You can't kill those who are too small, you can't kill those who are pregnant, you can't kill those with cubs, and you can't kill them in spring. After all, spring is the breeding season, preferably summer and autumn, but winter can also be used.

Over the years, my parents have abided by this rule, and what Tang Zhengqing just said touched their bottom line.

Lin Xuehan looked at Tang Zhengqing's appearance and envied her parents-in-law very much. They could teach Tang Zhengqing a lesson. When would she be able to reprimand her own children? Thinking of this, Lin Xuehan couldn't help but glance at Duoduo and Youyou, which made them

The two couldn't help but sneeze.

"Mom, should we go back or what? If we go back, I will ask Old Moore to prepare a cow, and we will roast the whole cow for dinner at night. If we don't go back, we will hunt here and make dinner by ourselves."

"It's better to go back. It's too dangerous here. If we adults are okay, there are still Duoduo and Youyou. They are so young. What if there are any wild animals?" Li Chunying said worriedly.

"Okay, let's go back first, and I will take you hunting tomorrow." Tang Zhengqing mainly said this to his father. His mother, Li Chunying, was not very interested in hunting. When she was in her hometown of Qingyun Village,

She also hasn't hunted a few times.

"Mom, you can use guns for hunting here in the United States, just like Lao Maozi. Tomorrow we will go hunting with guns. Don't you want to learn how to shoot?"

Tang Jianming was so excited. He still had endless memories of shooting at Lao Maozi's place at the beginning of the year. He never expected that he could still shoot here.

"Look at your potential!" Li Chunying glared at Tang Jianming angrily, knowing that her man must be excited.

"There are not many men who don't love firearms, especially us Chinese. We have never had the opportunity to play with guns. If you don't play with guns when you come to the United States, you would be doing yourself a disservice." Tang Jianming raised his head and said.

"Okay, okay, tomorrow, you and Xiaoqing will come over. I won't bring the children. They are still so young. What can I do if they shoot or scare the children?" For Li Chunying, children are the most important thing.

Yes, you two grown men can play by yourselves if you want, but don't spoil the children.

"Mom." Tang Zhengqing was about to say a few words but was interrupted by Li Chunying, "I know what you want to say. Just play with your dad. We won't play."

Tang Zhengqing had no choice but to glance at his father. Who knew that he was so happy that he didn't notice Tang Zhengqing's eyes at all.
