Geographical knowledge of world famous scenic spots

Yellowstone National Park is referred to as Yellowstone National Park for short. It is the first national park in the world, established in 1872. Yellowstone National Park is located in the northwest corner of Wyoming in the midwest of the United States, extending northwest to Idaho and Montana, covering an area of 8,956 square kilometers. This area was originally a sacred place for Indians, but it became the earliest national park in the world because of the excavation of American explorers Lewis and Clark. 1978 is listed as a world natural heritage. The natural landscape of the Geological Lion Fountain Yellowstone National Park is divided into five areas, namely Mamo District, Roosevelt District, Canyon District, Geyser District and Lake District. The five scenic spots have their own characteristics, but there is one uniqueness-geothermal wonders. There are 3,000 hot springs in Yellowstone National Park, including 300 geysers, many of which spray over 100 feet. The "Lion Fountain" is composed of four fountains, and the water column emits a sound similar to the roar of a lion before it is ejected, and then shoots into the air. The "sapphire fountain" is blue; The most famous "Old Faithful Spring" is named after its regular water spraying. From the discovery to now 100 years, it has erupted every 33-93 minutes, each eruption lasts for four or five minutes, and the water column is as high as 40 meters without interruption. The total length of roads in the park exceeds 500 miles, and the total length of trails exceeds 1000 miles. Yellowstone lake, Shoshone Lake, Shehe River and Huangshi River are distributed among them. The park is surrounded by castel, Shoshone, Teton, Thailand, Beaverhead and Galatin National Forests. Yellowstone National Park is a primitive earth landscape formed by water and fire. It is called "the most splendid and spectacular scenery on the earth's surface" and is described as "beyond the limits that human art can reach". Hot Springs As we all know, Huangshi is famous for its numerous hot springs, large and small geysers, colorful rocks, canyons, rivers and a wide variety of wild animals. This is a hotbed of geothermal activity, with more than 10 thousand geothermal characteristics; The Rocky Mountains have created countless beautiful mountains, rivers, waterfalls and canyons for this territory, and its limestone structure adds beautiful colors to the earth. Countless wild animals give it endless life. It is the hometown of Wyoming herds and the largest and most diverse mammal habitat in North America and even the world. At the beginning of the 20th century, an American explorer once described Yellowstone National Park as follows: "No matter how different the scenery and vegetation in different countries are, Mother Earth is always so familiar, kind and eternal. But here, the earth has changed so much that it seems to belong to another world. ..... The earth seems to test its endless creativity here. " The geothermal landscape of Yellowstone National Park is the most famous in the world. In fact, you can't help being shocked by the wonders you see. Thousands of boiling springs, blue lakes and deep pools are choppy, and the mountains are buzzing, as if a furnace of flames were burning. Hundreds of geysers spew boiling water columns and steam, like inverted waterfalls, spewing out from the hot and dark underground world from time to time. Some geysers have spectacular water columns, like towering trees, with diameters ranging from 1.5m to 18m and heights ranging from 45m to 90m. Great power can make it last for a few minutes at this height, and some can last for nearly an hour. Yellowstone National Park has the largest number of hot springs in the world, with more than 3,000 hot springs, mud springs and more than 300 geysers that regularly erupt! Geysers, in particular, are the pride of Huangshi. Because the total number of geysers in other parts of the world is not as much as that in Yellowstone National Park. Geysers are also found in Iceland, New Zealand, Japan, Himalayas, South America and many other volcanic areas. However, only in Iceland, New Zealand and this park do geysers show their most magnificent momentum and style. In these three famous areas, in terms of the number and scale of geysers, the geysers in Huangshi National Park are the first. Scientists have found that just under the surface of Huangshi, heat flow and lava activity are extremely active. The underground lava with a depth of 3300 meters provides sufficient energy for the hot springs. The lava of Baidu warms the underground spring water, which flows out, seeps out or gushes out from the cracks on the surface. This is the hot spring and hot spring that we see. The topography of Huangshi National Park is basically concave, and there is much snowfall in winter, which provides it with rich underground water sources. The water on the ground easily flows into the ground, and finally flows into the deep underground where the temperature far exceeds the boiling point, and is continuously heated by geothermal energy to change from cold to hot, and then turns into steam after boiling. Under great pressure, steam must find a way out. If the steam is blocked by the downward flowing water, the quality of the water will prevent the steam from escaping from the gap. In this way, after a period of time, because the pressure of steam is getting bigger and bigger, the heat is getting bigger and bigger, and finally it spews out with the spring water, forming a geyser. When a typical geyser is about to erupt, we can see water flowing out of a small hole first, or find that the water flow suddenly increases, and then thunder comes from deep underground, which means that steam has broken through the water barrier. Then, we will see that the water column of the nozzle is thrown up by steam for several seconds to several minutes. At the same time as the water column spouts out and for a period of time afterwards, we can still hear the rumble of water vapor, as if to vent our inner excitement. Finally, the underground pressure is released, and the power of steam jet disappears, so water begins to fill the nozzle again, blocking the outlet of steam and brewing the next eruption. Regardless of shape, size, winter and summer and weather conditions, all geysers are rising and sinking day and night faithfully, as if dancing rhythmically. This is the most peculiar flower cultivated by the creator. They bloom all year round and never feel tired or bored. These areas with dense "flowers" are generally called geyser basins, and most of them are open valleys located in the central plateau. When the larger volcanoes stopped burning, these valleys were formed by the erosion of glaciers. These valleys can be regarded as laboratories and kitchens of nature. In these thousands of "flasks" and "cookstoves", we can see that nature, like a skilled chemist or chef, mixes fire, water, gas and countless minerals. She cooks the whole mountain, barbecues the cliffs, and the huge Yellowstone National Park smokes everywhere with her superb skills. Huangshi Grand Canyon Huangshi Grand Canyon is located between the fishing bridge and the tower. The river flowing out of yellowstone lake flows through a steep canyon about 38km, commonly known as Huangshi Grand Canyon. This is the most magnificent and magnificent scenery in Yellowstone National Park. The 97-kilometer-long Yellowstone River is "the only river in America without dams". Here, the river suddenly became turbulent, and the splashing water was washed away, forming two magnificent waterfalls that roared and drained the Grand Canyon. One of these two waterfalls is 130 meters high, which is the upper waterfall; The other is 100 meters high and is called Xiapu. The Huangshi River passes through volcanic rocks, and after a long period of erosion, it forms the majestic Huangshi Grand Canyon, which is particularly steep and breathtaking, with a depth of 60 meters, a width of 200 meters and a length of about 32 kilometers. For those who come to watch this famous river section, what attracts them most is neither the depth and shape of the canyon nor the surging waterfall. The most unforgettable thing is the grotesque and colorful weathered volcanic rocks. The gorge wall shines with dazzling luster from head to toe, dazzling in the sun. White, yellow, green, blue, vermilion and countless colors in harmony with red. There are millions of tons of rocks in front of us, but they look like they are painted with oil paints, as if they are exposed to the wind and the sun without restraint. The color is very bright, and the solid color will not be washed away or faded by the wind and the sun. This effect is too strange and incredible.
