Wyoming was a former state of the United States it was completely devastated and depopulated by the Yellowstone super volcano eruption on July 1, 1909. Following a disaster and the complete destruction of the state was completely abandoned by the US government. The state itself pretty well ceased to exist after the eruption. The state was reclaimed by nature and by 1935 the state was a massive force with local wildlife, diversity of animals and new clean water. The state was not repopulated until 1944. However it was only a few small villages and agricultural settlements no cities existed and most of the state of the state park known as Wyoming national Park. A memorial was built in 1955 and all the people that died in the Yellowstone eruption. The monument was expanded further on the hundred anniversary of the eruption in 2009. The state continued to be sparsely populated and no cities were built. Wyoming continues to be a national park with rural communities. The US government ruled in 2011 that Wyoming should stay a state park in order to memorialize all the people that died in the early 20th century from volcanic eruption. The states colder temperatures also do not support large-scale agriculture which means the possibility of a large city is impossible. Some experts predict that the US government changes the rules a large city may be constructed in the state by 2025 at the earliest. The Wyoming disaster was the greatest disaster ever hit the United States second only to the San Francisco earthquake that leveled the city and made uninhabitable for centuries.
