November 29, 2021
Yellowstone National Park is a national park located in the United States and in the states of Wyoming, Montana and Idaho. The park was established by the United States Congress on March 1, 1872 as a national park in Wyoming and then expanded to Montana and Idaho. The park, signed by President Ulysses Simon Grant in March 1872, is the first national park in the United States and the first registered national park in the world. And it owes its fame to wildlife and the properties of its geothermal energy, and especially its popular appearance, the Old Fitful geyser. The national park has a variety of ecosystems, but mountain forests form the dominant ecosystem. Beneath the tranquil area of Yellowstone National Park in the United States is a huge reservoir of volcanic lava. The reason for the existence of geysers and hot springs that are the main feature of this region. Native Americans lived in the Yellowstone area more than 11,000 years ago. The area was discovered in the early 19th century during the travels of Lewis and Clark. In addition, mountain men visited the area in the mid-19th century, but Yellowstone was not organized until the 1860s. After the park was established, it was handed over to the United States Army, which remained in charge of the park until 1917, when it was transferred to the newly established National Parks Organization. Hundreds of buildings have been built in the area that are protected by historical or architectural significance, and researchers have discovered and studied more than 1,000 archeological sites in the park.
