Organ Pipe Cactus National Monument – Ajo, Arizona
The Organ PIpe Cactus National Monument was founded to celebrate the life and landscape of the Sonoran desert.
Whether you want to hike, take a drive on a lonely road, backpack, camp in the desert or just soak in the warmth and the beauty of the Southwest this is the place to do it.
There are extraordinary plants and animals in the Sonoran Desert for you to enjoy. These creatures adapted themselves to the extreme temperatures, intense sunlight and little rainfall of this Southwest region. There are Twenty-six species of cactus living here, including the beautiful park’s namesake and the giant saguaro.
Because this is a protected area, Organ Pipe Cactus National Monument has allowed the life of the Sonoran Desert to flourish under nearly ideal wilderness conditions. It is one of the Earth’s major ecosystems. In 1976 it was designated as an International Biosphere Reserve.
The park is home to the Gila Monster, one of only two species of poisonous lizards found in North America. They are out in the late spring through early autumn at the park but they move real slowly so you don’t have to worry about getting away from them to avoid getting bitten. They just want to be left alone.
The area also has ferruginous pygmy owls. They are so darling, such a delight to watch (please don’t try to touch or catch them, leave them to beautify the area in their natural habitat).
There are also Sonoran Pronghorns. T
his edgy, skittish and shy creature will run if it hears a car as far away as 2 miles! The Sonoran pronghorn is tinier than its more extroverted grassland sibling, the American pronghorn. This desert subspecies can freeze, invisible in the patchwork of cactus and rock. Fear is their survival strategy. It steers them away from highways, automobiles, and noisy humans. It makes them fast. It keeps them wary. With the dry season of 2002 many of them died leaving just 25 in the United States. The program to save them was begun in 2004 as scientists started a captive breeding program. 11 animals were caught, some from the larger herd in Mexico, to provide for genetic diversity. A square mile of desert was set aside in a non-wilderness are of Cabeza Prieta National Wildlife Refuge and through the care and hard work of the scientists involved the herd has begun to grow again. They seem to adapt to the wild very well once they are turned lose as they get big enough.
Coyotes are highly intelligent animals that are well adapted to survive in almost any environment. They are among the most common animals spotted in Organ Pipe Cactus National Monument and you might hear them "singing" on any given night.
The Organ Pipe Cactus National Monument is also a fabulous place for bird watching. There are a number of great sites to sit and watch for the bird you are interested in seeing show up. There is Alamo Canyon, Twin Peaks Campground, Ajo Mountan Drive, Kris Eggle Visitor Center or wherever you are hiking. The birds are fascinating and beautiful. Enjoy the experience.
