Painted Desert is the name for a broad area of badlands located in Northern Arizona in the United States. The desert stretches from the Grand Canyon National Park into the Petrified Forest National Park.
The popular name for the desert comes from the Colonial Spanish who are said to have named it El Desierto Pintado due to its brightly colored landscape.
The desert is composed of stratified layers of easily erodible siltstones, mudstones and shales of the Triassic Chinile Formation. These fine grained rock layers contain abundant iron and manganese compounds which provide the pigments for the various colors of the region.
