Organ Pipe Cactus National Monument celebrates the life and landscape of the Sonoran Desert. Here, in this desert wilderness of plants and animals and dramatic mountains and plains scenery three unique desert habitats converge within 500 square miles. The Monument exhibits an extraordinary collection of plants of the Sonoran Desert, including the Saguaro and Organ Pipe Cactus, a large cactus rarely found in the United States. There are also many creatures that have been able to adapt themselves to extreme temperatures, intense sunlight and little rainfall. Sonoran desert plants and animals, found nowhere else in the United States, are protected throughout the Monument and elsewhere in Arizona.
