United States. Arizona. Coconino County. The desert near Lake Powell. Lake Powell is a reservoir on the Colorado River, between Utah and Arizona. It is a vacation spot visited by two million people every year. It lies on an area of 161,390 acres (65,310 ha) and has 1960 miles (3161 km) of shoreline (more than the entire Pacific coast of USA). Because of its ecological effect on the Colorado River and on the environment, Lake Powell and its dam have inspired heavy controversy from environmentalists.

The Ajo Mountain Drive offers breathtaking views of the unique Sonoran Desert landscape, featuring a variety of flora and fauna. Two of the standout features of the area are the Organ Pipe Cactus (Stenocereus thurberi) and the Saguaro Cactus (Carnegiea gigantea). The Saguaro stands tall, often reaching heights of 40 feet or more and living up to two centuries. Its characteristic silhouette, adorned with 'arms' reaching towards the sky, serves as a testament to its endurance in harsh desert conditions.  In contrast, the Organ Pipe Cactus thrives in clusters, its slender stems resembling a congregation of organ pipes, hence its name. This cactus species flourishes in rocky terrain, its multiple stems serving as water reservoirs to survive extended periods of drought.  These two are endemic to the Sonoran Desert and found nowhere else in the world.  This scene , which includes Mount Ajo and Tillotson Peak, was photographed from the Ajo Mountain Drive in Organ Pipe Cactus National Monument south of Ajo, Arizona, USA.

Arch Canyon is a picturesque location located along the Ajo Mountain Drive in the Sonoran Desert of southern Arizona, near the border with Mexico. The Ajo Mountain Drive is a scenic loop road that offers visitors the opportunity to explore the diverse landscapes and natural features of the desert.  Arch Canyon is named for the natural arch formation that can be found within the canyon. The arch itself is a stunning geological feature created by erosion over thousands of years. It is composed of ancient volcanic rock and stands as a testament to the forces of nature that have shaped the landscape of the region.  Arch Canyon and the Arch Canyon Trail (pictured) are in the Organ Pipe Cactus National Monument south of Ajo, Arizona, USA.

Camelback Mountain is a prominent feature of the Sonoran Desert in southern Arizona.  It is part of the McDowell Mountain Range and is composed primarily of Precambrian granite.  The mountain has been weathered by rain, wind and other forces of nature over millions of years.  This erosion has given the mountain a distinctive hump-back “camel” shape thus leading to its name.  The area around Camelback Mountain is home to a variety of cacti, including saguaros, as well as a range of other desert plants and animals, such as jackrabbits, rattlesnakes, and Gila monsters. The mountain's summit provides a critical habitat for a number of bird species, including hawks, vultures, and eagles.  This view of the surrounding area was photographed from the Echo Canyon trail on Camelback Mountain near Phoenix, Arizona, USA.
