The short-lived Papago Saguaro National Monument 

Shortly after statehood in 1912, the Phoenix and Maricopa County Board of Trade began an effort to have what is now Papago Park declared either a national park or a national monument. Originally, the committee recommended the creation of a "National Cactus Park" just like Yellowstone National Park, the Yosemite National Park and the Mount Rainer National Park."
