The Grand Canyon was officially established as a United States national park in 1919. This designation followed earlier protections, with portions of the area first set aside as the Grand Canyon Forest Reserve in 1893, later redesignated as a game preserve and then a national monument by President Theodore Roosevelt. The creation of the National Park Service in 1916, driven by conservationists like John Muir, established the framework for preserving such natural wonders for future generations. The park's area was significantly expanded in 1975. In 1979, the Grand Canyon National Park was recognized as a UNESCO World Heritage site.123
