The Painted Desert is a United States desert of badlands in the Four Corners area,[2] running from near the east end of Grand Canyon National Park and southeast into Petrified Forest National Park. It is most easily accessed from the north portion of Petrified Forest National Park. The Painted Desert is known for its brilliant and varied colors: these include the more common red rock, but also shades of lavender.
History[]
The Painted Desert was named by a Spanish expedition under Francisco Vázquez de Coronado during his 1540 quest to find the Seven Cities of Cibola. He located these some 40 miles (60 km) east of Petrified Forest National Park. Finding the cities were not made of gold, Coronado sent an expedition to find the Colorado River to gain supplies. Passing through the wonderland of colors, they named the area El Desierto Pintado ("The Painted Desert").[3]
Much of the Painted Desert within Petrified Forest National Park is protected as Petrified Forest National Wilderness Area, where motorized travel is limited.[4] The park offers both easy and longer hikes into the colored hills. The Painted Desert continues north into the Navajo Nation, where off-road travel is allowed only by permit.
Geology[]
The desert is composed of stratified layers of siltstone, mudstone, and shale of the Triassic Chinle Formation, which erode easily. These fine-grained rock layers contain abundant iron and manganese compounds, which provide the pigments for the various colors of the region. Thin, resistant lacustrine limestone layers and volcanic flows cap the mesas. Numerous layers of silicic volcanic ash occur in the Chinle and provide the silica for the petrified logs of the area. The erosion of these layers has resulted in the formation of the badlands topography of the region.[5][6][7]
In the southern portions of the desert, the remains of a Triassic period coniferous forest have fossilized over millions of years. Wind, water and soil erosion continue to change the face of the landscape by shifting sediment and exposing layers of the Chinle Formation. An assortment of fossilized prehistoric plants and animals are found in the region, as well as ancient dinosaur tracks and the evidence of early human habitation.
Area and climate[]
The Painted Desert extends roughly from Cameron–Tuba City southeast to past Holbrook and the Petrified Forest National Park. The desert is about 120 miles (190 km) long by about 60 miles (100 km) wide, making it roughly 7,500 square miles (19,420 km2) in area.[8] Bordering southwest and south is the Mogollon Plateau, and on the plateau's south border the Mogollon Rim, the north border of the Arizona transition zone.
Owing to the strong rain shadow of the Mogollon Rim, the Painted Desert has a cold desert climate (Köppen BWk), with hot, dry summers and chilly (though virtually snow-free) winters. The annual precipitation is the lowest in northern Arizona and in many places is lower even than Phoenix.[9]

Accessibility[]
Much of the region is accessible only by foot or unpaved road though major highways and paved roads cut across the area. The towns of Cameron and Tuba City, both on the Navajo Nation, are two major settlements. A permit is required for all backroad travel on the Navajo Nation.[11]
