The park hosts special events related to Earth Science Week and National American Indian Heritage Month . On Saturdays from Memorial Day weekend through Labor Day at the Painted Desert Inn, artisans from the region give cultural demonstrations related to ancient peoples, intertribal relationships, and European-descent cultures. For students and teachers,

1079-530: Is a national park of the United States in Navajo and Apache counties in northeastern Arizona . Named for its large deposits of petrified wood , the park covers about 346 square miles (900 square kilometers), encompassing semi-desert shrub steppe as well as highly eroded and colorful badlands . The park's headquarters is about 26 miles (42 km) east of Holbrook along Interstate 40 (I-40), which parallels

1162-791: Is about 120 miles (190 km) long by about 60 miles (100 km) wide, making it roughly 7,500 square miles (19,420 km ) in area. 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

1245-487: Is allowed in the wilderness areas; water for horses is available at the service station near the Painted Desert Visitor Center. Riders and hikers are asked to travel along dry washes as much as possible to reduce the impact on fragile desert soils. Rangers offer a variety of programs about the park. Regularly scheduled events include a Painted Desert Inn tour, a Triassic program at the Rainbow Forest Museum sunroom,

1411-452: Is not allowed except in the case of backpackers with wilderness hiking permits. Sightseeing is available by private automobile, motorcycle, commercial tour, bicycle, and hiking. The park road, parking lots, and turn-outs are big enough to accommodate large recreational vehicles. Off-road vehicle travel, including by mountain bike , is not allowed. With a few exceptions such as unpaved Old Highway 66, bicycles must stay on paved roads such as

1494-629: Is now deposited at the University of California Museum of Paleontology . In 1919, a phytosaur skull was discovered near Blue Mesa in the Petrified Forest by Ynez Mexia and sent to the Museum of Paleontology in Berkeley. In 1921, Annie Alexander , founder of the museum, visited Blue Mesa to collect more of the phytosaur and other specimens; this led to further excavations by paleontologist Charles Camp . Camp

1577-498: Is semi-desert shrub steppe. Protected from development and overgrazing for many years, the park has some of the best grassland in northeastern Arizona. In the northern part of the park, the volcanic soils of the Bidahochi Formation support abundant plant life along the Painted Desert rim. In contrast to the relatively bare badlands below, the rim is covered with shrubs, small trees, grasses, and herbs. The dominant plants in

1660-450: Is still a problem. Despite a guard force of seven National Park Service rangers , fences, warning signs, and the threat of a $ 325  fine , an estimated 12 short tons (11,000  kg ) of the fossil wood is stolen from the Petrified Forest every year. Jessee Walter Fewkes , the first archeologist to visit Puerco Ruin, predicted in the late 19th century that it would yield many artifacts. Conservationist John Muir conducted

1743-416: Is the golden eagle , with a wingspan of up to 7 feet (2 m). The park is open every day except Christmas on a schedule that varies slightly with the seasons. In 2010, it and its Painted Desert Visitor Center and Rainbow Forest Museum were open from 7 a.m. to 7 p.m. from May 9 through September 6 but opened as early as 8 a.m. and closed as late as 5 p.m. during other parts of

1826-400: Is the largest and most often seen. Plateau striped whiptails , a species consisting entirely of females, prefer grasslands and developed areas. Side-blotched lizards live in rocky areas of the park but are seldom seen. Gopher snakes , which sometimes imitate rattlesnakes when disturbed, are among the most common snakes in the park. The Prairie rattlesnake , the only venomous snake found in

1909-498: Is the lowest in northern Arizona and in many places is lower even than Phoenix . 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.

1992-573: The Archaic Period , nomadic groups established seasonal camps in the Petrified Forest from which they hunted game such as rabbits, pronghorn antelope, and deer and harvested seeds from Indian ricegrass and other wild plants. By at least 1000  BCE and through the Basketmaker II period (400  BCE –500  CE )Ancestral Puebloan farmers began to grow corn. Between 200–500  CE population size grew rapidly. Many families built houses in

2075-512: The BNSF Railway 's Southern Transcon , the Puerco River , and historic U.S. Route 66 , all crossing the park roughly east–west. The site, the northern part of which extends into the Painted Desert , was declared a national monument in 1906 and a national park in 1962. The park received 644,922 recreational visitors in 2018. Averaging about 5,400 feet (1,600 m) in elevation, the park has

2158-475: The BNSF Railway , and the Puerco River bisect the park generally east–west along a similar route. Adamana , a ghost town , is about 1 mile (1.6 km) west of the park along the BNSF tracks. Holbrook , about 26 miles (40 km) west of park headquarters along I-40, is the nearest city. Bisecting the park north–south is Park Road, which runs between I-40 near park headquarters on the north and U.S. Route 180 on

2241-509: The Bureau of Land Management , and private land, much of it used for cattle ranching, adjoin the other borders. The park's elevation above sea level varies from a low of 5,340 feet (1,630 m) along the Puerco River to a high of 6,230 feet (1,900 m) at Pilot Rock; the average elevation is about 5,400 feet (1,650 m). The terrain varies from gentle hills and major petrified wood deposits in

2324-665: The Colorado Plateau , of which the park is part, was pushed upward by tectonic forces and exposed to increased erosion. All of the park's rock layers above the Chinle, except geologically recent ones found in parts of the park, have been removed by wind and water. In addition to petrified logs, fossils found in the park have included Late Triassic ferns, cycads , ginkgoes , and many other plants as well as fauna including giant reptiles called phytosaurs , large amphibians, and early dinosaurs. Paleontologists have been unearthing and studying

Much of the Painted Desert within Petrified Forest National Park is protected as Petrified Forest National Wilderness Area , where motorized travel is limited. The park offers both easy and longer hikes into the colored hills. The Painted Desert continues north into

2490-588: The Mesozoic era, about 225-207 million years ago. During this epoch, the region that is now the park was near the equator on the southwestern edge of the supercontinent Pangaea , and its climate was humid and sub-tropical. What later became northeastern Arizona was a low plain flanked by mountains to the south and southeast and a sea to the west. Streams flowing across the plain from the highlands deposited inorganic sediment and organic matter, including trees as well as other plants and animals that had entered or fallen into

2656-551: The Navajo Nation , where off-road travel is allowed only by permit. 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

2739-625: The Painted Desert gets its name, is up to 800 feet (240 m) thick in the park. It consists of a variety of sedimentary rocks including beds of soft, fine-grained mudstone , siltstone , and claystone —much of which is bentonite —as well as harder sandstone and conglomerate , and limestone . Exposed to wind and water, the Chinle usually erodes differentially into badlands made up of cliffs, gullies, mesas , buttes , and rounded hills. Its bentonite clay, which swells when wet and shrinks while drying, causes surface movement and cracking that discourages plant growth. Lack of plant cover makes

2822-521: The Placerias Quarry near St. Johns . Fossil invertebrates include freshwater snails and clams . The oldest fossil crayfish , Enoploclytia porteri , was also described from the park, although it is not considered a crayfish proper (instead placed in Erymidae ). New animal species that were first identified from localities within the current park boundaries, some of which remain known only from

Although this first attempt failed, in 1906 the Antiquities Act signed by President Theodore Roosevelt was used to create the Petrified Forest National Monument as the second national monument . Between 1934 and 1942, the federal Civilian Conservation Corps built road, trails, and structures in the monument, and the government acquired additional land in

2988-429: 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. 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

3071-522: The 10-mile-per-hour (16 km/h) average wind causes frequent sandstorms and dust devils , some of which reach altitudes of several thousand feet. Rain is heaviest from July through September, when 42 percent of the park's annual average precipitation falls. August is the wettest month. At an elevation of more than 5,000 feet (1,500 m), Petrified Forest National Park has a chance of light snow from October through March, although snow cover rarely persists.

The park's seven maintained hiking trails, some paved, vary in length from less than 0.5 miles (0.8 km) to nearly 3 miles (4.8 km). Pets are allowed on these trails if kept on a leash, but bicycles are not. These named trails are Painted Desert Rim, Puerco Pueblo, Blue Mesa, Crystal Forest, Giant Logs, Long Logs, and Agate House. There are also nine recently developed day-hike routes on unpaved and largely unmarked routes called "Off

3237-465: The 35th Parallel Route (also known as the Beale Camel Trail). The Painted Desert Inn was upgraded to a National Historic Landmark in 1987. The visitor center, which is near the north entrance to the park, offers visitor information and shows a 20-minute orientation movie, "Timeless Impressions", once every half-hour. It has a bookstore, exhibits, a restaurant open from 8 a.m. to 3 p.m.,

3486-579: The Chinle and Bidahochi. Older dunes range in age from 500,000 years at higher elevations in the northern part of the park to about 10,000 years in sandy drainage areas such as Lithodendron Wash. Stabilized by grasses and other vegetation, young dunes of about 1,000 years old are found throughout the park. During the Late Triassic, downed trees accumulating in river channels in what became the park were buried periodically by sediment containing volcanic ash . Groundwater dissolved silica (silicon dioxide) from

3569-470: The Chinle especially susceptible to weathering. About 60 million years ago, tectonic movements of the Earth's crust began to uplift the Colorado Plateau , of which the Painted Desert is part. Eventually parts of the plateau rose to 10,000 feet (3,000 m) above sea level. This warping of the Earth's surface led to the gradual and continuing destruction of the plateau by erosion. An unconformity (break in

3652-648: The Hopi Mesas in Northern Arizona and at the Pueblo of Zuni in northern New Mexico, where the descendants of the ancient Petrified Forest farmers still live today. Some researchers have argued that a persistently dry climate led to out-migration, and the last residents left Puerco Pueblo in about 1380 CE. At Puerco Pueblo and many other sites within the park, petroglyphs —images, symbols, or designs—have been scratched, pecked, carved, or incised on rock surfaces, often on

3735-547: The Painted Desert section. The monument became a national park in 1962. Six years after the signing of the Wilderness Act in 1964 by President Lyndon B. Johnson , wilderness areas (where human activity is limited), were designated in the park. In 2004, President George W. Bush signed a bill authorizing the eventual expansion of the park from 93,353 acres (about 146 mi or 378 km ) to 218,533 acres (about 341 mi or 884 km ). Theft of petrified wood

3818-454: The Painted Desert. However, the park's oldest Spanish inscriptions, left by descendants of the region's early Spanish colonists, date only to the late 19th century. After the Southwest became part of the U.S. , explorers continued to look for good east–west routes along the 35th parallel . In 1853, a crew led by U.S. Army Lieutenant Amiel Whipple surveyed along a sandy wash in

3901-481: The Petrified Forest and for the first time began to stay there year-round. During the Basketmaker III period, 500–700  CE , families occupied shallow subterranean pit structures, at first on mesas or other vantage points and later at the base of bluffs and in lowlands, where the soil was better. Settlement patterns shifted and population size grew during the Pueblo I era between 700 and 900 CE and for

3984-513: The Petrified Forest in the early 1940s identified most of the large sites with stone ruins, and subsequent surveys since 1978 have identified a total of more than 600 artifact sites, many of them small. The earliest paleontological exploration of the region that is now the park was made in 1899 by paleobotanist Lester Ward , material of which is now deposited in the Smithsonian Institution . Muir also collected some fossil material, which

4067-435: The Petrified Forest migrated to join rapidly growing communities on the Hopi Mesas to the northwest and the Pueblo of Zuni to the east–these locations are still home to thousands of descendant community members today. More than 1000 archeological sites, including petroglyphs , have been discovered in the park. These ancestral places remain important to descendant communities. In the 16th century, Spanish explorers visited

4150-540: The University of Chicago (Michael Parrish), the Field Museum of Natural History (John Bolt), and Yale University (Paul Olsen). Since then, more than 300 fossil sites have been documented in the park. Research in paleontology and archeology continues at the park in the 21st century. According to the A. W. Kuchler U.S. Potential natural vegetation Types, Petrified Forest National Park encompasses two classifications;

4233-444: The area is below 50 percent and at times less than 15 percent. More than 1200 archeological sites have been found inside the boundaries of Petrified Forest National Park. Evidence suggests that the earliest inhabitants of the park arrived over 12,000 years ago. Clovis and Folsom-type spear points made from petrified wood are among the earliest artifacts of Paleoindians found in the park. Between 8,000 and 1,000  BCE ,

4316-422: The area, and by the mid-19th century a U.S. team had surveyed an east–west route through the area where the park is now located and noted the petrified wood. Later, roads and a railway followed similar routes and gave rise to tourism and, before the park was protected, to large-scale removal of fossils. Theft of petrified wood remains a problem in the 21st century. Petrified Forest National Park straddles

4399-403: The ash and carried it into the logs, where it formed quartz crystals that gradually replaced the organic matter. Traces of iron oxide and other substances combined with the silica to create varied colors in the petrified wood. In Petrified Forest National Park, most of the logs in the park retained their original external form during petrification but lost their internal structure. However,

4482-424: The border between Apache County and Navajo County in northeastern Arizona. The park is about 30 miles (50 km) long from north to south, and its width varies from a maximum of about 12 miles (20 km) in the north to a minimum of about 1 mile (1.6 km) along a narrow corridor between the north and south, where the park widens again to about 4 to 5 miles (6 to 8 km). I-40 , former U.S. Route 66 ,

4565-533: 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 evidence of early human habitation. The Painted Desert extends roughly from Cameron – Tuba City southeast to past Holbrook and the Petrified Forest National Park . The desert

4648-786: The fastest land animals in North America, are capable of 60-mile-per-hour (97 km/h) sprints. They are the second fastest land animal on Earth. The blood vessels in the huge, thin-walled ears of the jackrabbits act as heat exchangers. These hares are known for their bursts of speed, long leaps, and zigzag routes, all of which protect them from being eaten by golden eagles and other predators. The prairie dogs live in large colonies or "towns", near which many other species find food and shelter. Coyotes dine largely on rodents but also eat fruits, reptiles, insects, small mammals, birds, and carrion . Bobcats and bullsnakes hunt smaller animals, such as deer mice and white-tailed antelope squirrels in

4731-532: The first excavations of the ruin in 1905–06. Although he did not publish his findings, he urged the federal government to preserve Petrified Forest. Professional archeological work in the park began in the early 20th century when Walter Hough conducted excavations at Puerco Ruin and other sites. In the 1930s, the Civil Works Administration funded research in the park by archeologists H.P. Mera and C.B. Cosgrove. A National Park Service resurvey of

4814-542: The first time large groups of families aggregated together and formed large villages. During this period, each household built large well-insulated subterranean residential pit structures to keep warm during the cold winter months and several adjacent above ground rooms made from stone and jacal similar to adobe—used for food storage and daily activities during the warmer months. During the early Pueblo II period (900–1050  CE ) Ancestral Pueblo farmers began constructing above-ground masonry architecture (for example Agate House,

4897-504: The late 19th century, settlers and private stagecoach companies followed similar east–west routes. Homesteaders who stayed in the area developed cattle ranches on the grasslands, and cattle grazed in the Petrified Forest until the mid-20th century. Also close to the 35th parallel was the Atlantic and Pacific Railroad . Its opening in the early 1880s led to the founding of towns like Holbrook and Adamana. Visitors could stop at

4980-548: The northern part of the Petrified Forest. So impressed was Whipple by the petrified wood along the banks of the arroyo that he named it Lithodendron Creek (Stone Tree Creek). Geologist Jules Marcou , a member of the Whipple expedition, observed that the petrified trees were from the Triassic. A slightly later route along the parallel was a wagon road, built between 1857 and 1860, that involved experimental use of camels as transport. In

Growing among the grasses are flowering species such as evening primrose , mariposa lily , and blue flax , and shrubs such as sagebrush , saltbush , and rabbitbrush . Among the wide variety of grasses are native perennial bunchgrass , blue grama , sacaton , sideoats grama , bearded sprangletop , and bush muhly . Invasive species that crowd out slower-spreading natives include annual lovegrass and brome (cheat grass). Trees and shrubs grow in riparian zones along

5312-485: The park is designated wilderness —50,260 acres (79 sq mi; 203 km ). The Petrified Forest is known for its fossils, especially fallen trees that lived in the Late Triassic Epoch , about 225 million years ago. The sediments containing the fossil logs are part of the widespread and colorful Chinle Formation , from which the Painted Desert gets its name. Beginning about 60 million years ago,

5395-535: The park's fossils since the early 20th century. The park's earliest human inhabitants arrived 13,000 years ago. These Clovis-era people are the ancestors of Native Americans. By about 2,500 years ago Ancestral Pueblo farmers were growing corn and living in subterranean pit houses in what would become the park. By one-thousand years ago Ancestral Pueblo farmers lived in above-ground, masonry dwellings called pueblos and gathered in large communal buildings called great kivas. By AD 1450 Ancestral Pueblo farmers in

5478-552: The park's riparian zones. Western pipistrelle bats feast on insects, and pallid bats eat beetles, centipedes , cicadas , praying mantises , scorpions , and other arthropods . On the Painted Desert rim, small animals find food and shelter among the denser foliage, and mule deer sometimes frequent the area. More than 16 kinds of lizards and snakes live in various habitats in the park and consume large quantities of insects, spiders, scorpions, other reptiles, and small mammals. The collared lizard , which occurs in every habitat,

5561-479: The park's washes. Willows and cottonwoods are the larger plants, joined by rushes and sedges. Here the invasive Eurasian tamarisk , also known as saltcedar, threatens native plants by crowding, using most of the available water, and increasing soil salinity by exuding salt through its leaves. Some of the larger animals roaming the grasslands include pronghorns , black-tailed jackrabbits (hares), Gunnison's prairie dogs , coyotes , bobcats and foxes. Pronghorns,

The greatest diversity of birds occurs during fall and winter migrations. Raptors , songbirds, and ground birds are found in the park's grassland, while the Puerco River's riparian corridor is a good place for year-round residents as well as migrants such as warblers , vireos , avocets , and killdeer . Developed areas around

According to the United States Department of Agriculture , the plant hardiness zone at the Painted Desert Visitor Center 5,764 feet (1,757 m) is 7a with an average annual extreme minimum temperature of 3.1 °F (−16.1 °C). Winter winds can reach 60 miles per hour (97 km/h). Summer breezes are lighter, but

5893-543: The park, prefers grasslands and shrub areas. Seven kinds of amphibians , which drink no water but absorb it through their permeable skins, have been identified in Petrified Forest National Park. Tiger salamanders , found in grassland and near major drainages, are the only salamander species known in Arizona. Woodhouse's toads , which are seldom seen, are the largest toads in the park. They like grasslands, riparian corridors, and developed areas. Red-spotted toads , most active in

5976-575: The park—on Pilot Rock in the park's wilderness section and along the rim of the Painted Desert between Pintado and Tawa points. Exposed by erosion of the Bidahochi are volcanic landforms called maars (flat-bottomed, roughly circular volcanic craters of explosive origin). A maar vent can be seen from the Pintado Point lookout. During the Quaternary Period (2.6 million years ago up to today), deposits of windblown sand and alluvium covered much of

6059-475: The railroad tracks until it was decommissioned in 1985. The park has preserved within its boundaries a small grassy section of the road. Interstate 40 , which crosses the park, replaced the older highway. Increasing tourist and commercial interest in petrified wood during the late 19th century began to alarm residents of the region. In 1895, the Arizona Territorial Legislature asked

6142-510: The rainy season, July through September, are found in rocky areas near streams and in canyons. The Great Plains toad , the most common toad in the park, prefers grasslands. Resident spadefoot toads include the New Mexico, plains, and Couch's varieties. A survey conducted in 2006 identified 216 species of birds known to have occurred in Petrified Forest National Park since the park became a protected area in 1906. Of those, 33 species breed within

6225-645: The richest Late Triassic fossil-plant deposits in the world, contains more than 200 fossil plant taxa . Plant groups represented in the park include lycophytes , ferns , cycads , conifers, ginkgoes , as well as unclassified forms. The park has also produced one of the most diverse assemblages of fossil vertebrates from the Late Triassic. Among the groups represented are early theropod dinosaurs, crocodile-line archosaurs, temnospondyl amphibians, lissamphibians, non-archosauromorph diapsids, and other dinosauromorphs and archosauromorphs. Dicynodonts are extremely rare despite being abundantly represented at

6308-507: The rock record) of about 200 million years occurs within the park, where erosion has removed all the rock layers above the Chinle except geologically recent ones. The Bidahochi Formation , laid down only 4 to 8 million years ago, rests directly atop the Chinle, and rocks laid down in the Jurassic , Cretaceous , and much of the Tertiary are absent. During the period of the Bidahochi deposition ,

Anna's hummingbird , which can hover and fly backwards as well as forwards, is among the smallest birds in the park. The largest

6723-459: The water. Although most organic matter decays rapidly or is eaten by other organisms, some is buried so quickly that it remains intact and may become fossilized. Within the park, the sediments containing the fossil logs for which the park is named are part of the Chinle Formation . The colorful Chinle, which appears on the surface in many parts of the southwestern United States and from which
