The Historical Evolution of yellowstone lake

Yellowstone lake is located in Yellowstone National Park. The first white man to enter Yellowstone National Park was JohnColter. He is a hunter in a famous expedition. He didn't go back to China with other team members after the expedition completed its mission to the west. He accepted the invitation of two fur hunters to hunt fur in Huangshi Valley. 1807, he accepted the entrustment of a newly established fur company and went back to the mountains to hunt. This time, he entered the scope of today's Yellowstone National Park and witnessed the boiling hot springs. He thought he had gone to hell, and no one believed what he saw when he went back to tell others. Later, he and many hunters went to Huangshi again to look for otters. The natural landscape of Yellowstone National Park, especially the wonderful phenomenon of geysers erupting regularly, has opened their eyes, but it is still difficult to win the trust of others. It was not until more than 30 years later that the first expedition composed of three whites came to explore and entered Huangshi in September 1869. Everyone was shocked by the magnificent scenery. 1870 in August, four explorers from Montana, Nathaniel. Langford, General Henry washburne, Cornelius Shedgis and Lieutenant gustavus Donne decided to form a 65438 after hearing the description of Huangshi by the last expedition. They stayed in Huangshi for more than a month, systematically inspected the whole Huangshi area, recorded all the geographical landscapes in detail, and named the hot springs, rivers and peaks. One night after the expedition, everyone chatted around the bonfire and decided that this area should not belong to anyone and should be classified as a "national park". In June165438+1October of the same year, Heggis began to promote the concept of "national park" in a newspaper in Montana, and Langford toured the east to publicize the wonders of Yellowstone National Park.

Their efforts finally got the attention of the US Congress. 187 1 year, Congress agreed to allocate funds to send an official investigation team to inspect Huangshi along the Snake River. The team was led by FerdinandVandiveerHayden, accompanied by photographers in addition to complete equipment and funds. It has achieved fruitful results and has been affirmed by Congress. On March 1872, an unprecedented bill was passed, stipulating that Huangshi area "will be preserved under the laws of the United States from now on and shall not be reclaimed, occupied or traded. For the well-being and enjoyment of the people, President Grant announced that a national park was born in the world. "
