Saguaro National Park is a United States national park in southeastern Arizona that preserves  Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus. The 92000 acre park has two separate areas—the Tucson Mountain District (TMD) about 10 mi west of the city of Tucson and the Rincon Mountain District about 10 mi east of the city. The Rincon Mountains are part of the Madrean Sky Islands between the southern Rocky Mountains and the Sierra Madre Oriental in Mexico; they are significantly higher and wetter than the Tucson Mountains, and support many plants and animals that do not live in the TMD. Earlier residents of and visitors to the lands in and around the park before its creation included the Hohokam, Sobaipuri, Tohono O'odham, and Apaches, as well as Spanish explorers, missionaries, miners, homesteaders, and ranchers. In 1933, President Herbert Hoover, using the Antiquities Act, established the original park, Saguaro National Monument, in the Rincon Mountains. In 1961, President John F. Kennedy added the TMD.
