“By the great river plain” means Wyoming xwé:wam?nk in the language of the Munsee (also Munsee Delaware, Delaware, or Ontario Delaware), a group of eastern Algonquian Indians. The region was given that name in 1865 after Ohio Representative JM Ashley submitted a bill to Congress establishing an interim government for “the Territory of Wyoming. ” Incidentally, this name was originally given to the “Wyoming Valley” in Pennsylvania, which became known in 1809 through Thomas Campbell ‘s poem Gertrude of Wyoming. The state of Wyoming is part of the western United States. Most of the state is in the western Rocky Mountains and foothills. Large areas of the east belong to the prairie region of the “High Plains”. Wyoming is the tenth largest state in the United States, but has the lowest population of all with approximately 525,000 inhabitants. At the end of the 18th century to the beginning of the 19th century, a number of expeditions came to the country and explored the area. In 1807, John Colter, a member of the Lewis & Clark Expedition, described the northern regions of the state. At the time, his accounts of what is now the Yellowstone area were dismissed as fictitious. A milestone in the region’s development was the completion of the Union Pacific Railroad. When the railroad arrived in Cheyenne in 1867, the population there was growing rapidly. Significant mineral resources have not been discovered, such as gold and silver deposits in Colorado. Copper has been found in some areas near the Sierra Madre. When the government funded some expeditions to the Yellowstone area, the reports from Colter and other pioneers turned out to be largely true. Yellowstone National Park was established in 1872 as the world’s first national park. Check topschoolsoflaw.com for brief history of the state of Wyoming.
