Yellowstone National Park in Wyoming celebrates 150 years! The park – 96% in Wyoming, 3% in Montana and 1% in Idaho, is celebrating a major milestone this year. In the past 150 years, Yellowstone has given many people so many amazing memories with its beautiful features. On March 1st, 1872, President Ulysses S. Grant signed the Yellowstone National Park Protection Act into law. With his signature, he created the first national park in the United States and in the world! “Some of the modern trails frequented by hikers in Yellowstone are believed to be relics of Indigenous corridors dating all the way back to roughly 12,000 years ago,” the US Geological Survey says. https://www.cnn.com/travel/article/yellowstone-national-park-150th-anniversary/index.html
