Organ Pipe Cactus National Monument - Natural Features

Organ Pipe Cactus National Monument lies in an area of wide alluvial basins separated by steep mountain ranges. Elevations range from 981 in the Southwest corner of the monument to 4800 feet at the top of Mt. Ajo, the highest peak in the monument. The mountains are all volcanic in origin and make an excellent stop for students studying the geology of the Southwest. Another natural feature in the monument are the rare springs that bring life to the desert. Quitobaquito springs are the most easily visited and the largest in the monument. These wetland areas contain a diversity of plants and also attract wildlife from the surrounding desert.
