57-576: Joshua Tree National Park is a national park of the United States in southeastern California , east of San Bernardino and Los Angeles and north of Palm Springs . It is named after the Joshua trees ( Yucca brevifolia ) native to the Mojave Desert . Originally declared a national monument in 1936, Joshua Tree was redesignated as a national park in 1994 when the U.S. Congress passed
114-488: A box canyon at Cow Camp . Throughout the region, ranchers dug wells and built rainwater catchments called "tanks", such as White Tank and Barker Dam . In 1900, C. O. Barker, a miner and cattleman, built the original Barker Dam, later improved by William "Bill" Keys, a rancher. Grazing continued in the park through 1945. Barker Dam was added to the National Register of Historic Places (NRHP) in 1975. Between

Most of the structures associated with the mine fell apart, and for safety reasons the National Park Service plugged the mine, which had collapsed. The Desert Queen Mine on Keys' Desert Queen Ranch was another productive gold mine. In the early 1930s, Keys bought
285-603: A campground. Shorter trails, such as the one-mile hike through Hidden Valley, offer a chance to view the beauty of the park without straying too far into the desert. A section of the California Riding and Hiking Trail meanders for 35 miles (56 km) through the western side of the park. The lookout point at Keys View, towards the south of the park, offers views of the Coachella Valley, the Salton Sea ,
342-475: A destination, and hunting and extractive activities are prohibited. National monuments , on the other hand, are also frequently protected for their historical or archaeological significance. Eight national parks (including six in Alaska ) are paired with a national preserve , areas with different levels of protection that are administered together but considered separate units and whose areas are not included in

Some of the mines in the park yielded copper, zinc, and iron. On August 10, 1936, after Minerva Hoyt and others persuaded the state and federal governments to protect the area, President Franklin D. Roosevelt used the power of
456-543: A mission in San Diego. By 1823, the year Mexico achieved independence from Spain, a Mexican expedition from Los Angeles, in what was then Alta California , is thought to have explored as far east as the Eagle Mountains in what later became the park. Three years later, Jedediah Smith led a group of American fur trappers and explorers along the nearby Mojave Trail , and others soon followed. Two decades after that,

Birds, lizards , and ground squirrels are most likely to be seen because they are largely active during the day. However, at night, nocturnal desert animals are active. Mostly nocturnal animals include snakes , bighorn sheep , kangaroo rats , coyotes , bobcats , and black-tailed jackrabbits . The desert tortoise
969-546: The California Desert Protection Act . Encompassing a total of 795,156 acres (1,242.4 sq mi; 3,217.9 km) – slightly larger than the state of Rhode Island – the park includes 429,690 acres (671.4 sq mi; 1,738.9 km) of designated wilderness . Straddling San Bernardino and Riverside Counties, the park includes parts of two deserts, each an ecosystem whose characteristics are determined primarily by elevation:
1026-520: The Colorado Desert encompasses the eastern part of the park and features habitats of creosote bush scrub, ocotillo , desert saltbush , and mixed scrub including yucca and cholla cactus ( Cylindropuntia bigelovii ). Some areas of such cactus are dense enough to appear as natural gardens. The lower Coachella Valley is on the southeastern side of the park with sandy soil grasslands and desert dunes . The only palm native to California,
1083-869: The Mojaves , used the local resources as they traveled along trails between the Colorado River and the Pacific coast. In the 21st century, small numbers of all four peoples live in the region near the park; the Twentynine Palms Band of Mission Indians , descendants of the Chemehuevi, own a reservation in Twentynine Palms. In 1772, a group of Spaniards led by Pedro Fages made the first European sightings of Joshua trees while pursuing native converts to Christianity who had run away from
1140-700: The National Park Service , an agency of the Department of the Interior . National parks are designated for their natural beauty, unique geological features, diverse ecosystems, and recreational opportunities, typically "because of some outstanding scenic feature or natural phenomena." While legislatively all units of the National Park System are considered equal with the same mission, national parks are generally larger and more of
1197-528: The green darner Anax junius , and the giant desert scorpion Hadrurus arizonensis are arthropods that can grow to be more than 4 inches (10 cm) long. The yucca moth Tegeticula synthetica is responsible for pollinating the Joshua trees after which the park is named. Animals that thrive in Joshua Tree often have special adaptations for dealing with limited water and high summer temperatures. The smaller mammals and all reptiles take refuge from

The state with the most national parks is California with nine, followed by Alaska with eight, Utah with five, and Colorado with four. The largest national park is Wrangell–St. Elias in Alaska: at over 8 million acres (32,375 km ), it is larger than each of the nine smallest states . The next three largest parks are also in Alaska. The smallest park
1368-528: The 1860s and the 1940s, miners worked about 300 pit mines, mostly small, in what later became the park. The most successful, the Lost Horse Mine , produced gold and silver worth about $ 5 million in today's currency. Johnny Lang and others, the original owners of the Lost Horse Mine, installed a two- stamp mill to process ore at the site, and the next owner, J.D. Ryan , replaced it with
1425-538: The 1906 Antiquities Act to establish Joshua Tree National Monument, protecting about 825,000 acres (1,289.1 sq mi; 3,338.7 km). In 1950, the size of the park was reduced by about 290,000 acres (453.1 sq mi; 1,173.6 km) to open the land to more mining. The monument was redesignated as a national park on October 31, 1994, by the Desert Protection Act , which also added 234,000 acres (365.6 sq mi; 947.0 km). In 2019,
1482-539: The California fan palm ( Washingtonia Filifera ), occurs naturally in five oases in the park, rare areas where water occurs naturally year-round, and all forms of wildlife abound. Invasive plants such as cheat grass and red brome contribute to the worsening of wildfires. During wetter periods fills in below and among the pines and oak. In drier times, they die back but do not quickly decompose. This makes wildfires hotter and more destructive, which kills some of

1824-474: The annual temperature has increased by 3 °F. Because of the hotter and drier conditions, there are more wildfires in the park. The park's oldest rocks, Pinto Gneiss among them, are 1.7 billion years old. They are exposed in places on the park's surface in the Cottonwood , Pinto , and Eagle Mountains. Much later, from 250 to 75 million years ago, tectonic plate movements forced volcanic material toward
1881-490: The climate was wetter until the 1930s, with the same hot and dry conditions that provoked the Dust Bowl affecting the local climate. These cycles were nothing new, but the original vegetation did not prosper when wetter cycles returned. The difference may have been human development. Cattle grazing took out some of the natural covers and made it less resistant to the changes. There are fewer Joshua tree seedlings surviving in

Joshua trees dominate the open spaces of the park, but in among the rock outcroppings are piñon pine , California juniper ( Juniperus californica ), Quercus turbinella (desert scrub oak), Quercus john-tuckeri (Tucker's oak), Quercus cornelius-mulleri (Muller's oak), Cylindropuntia chuckwallensis (chuckwalla cholla), and Opuntia chlorotica (dollarjoint pricklypear). These communities are under some stress, however, as
1995-552: The figures below. The 431 units of the National Park System can be broadly referred to as national parks, but most have other formal designations. A bill creating the first national park, Yellowstone , was signed into law by President Ulysses S. Grant in 1872, followed by Mackinac National Park in 1875 (decommissioned in 1895), and then Rock Creek Park (later merged into National Capital Parks ), Sequoia and Yosemite in 1890. The Organic Act of 1916 created

Reptiles are physiologically adapted to getting along with little water, and birds can fly to water sources when they need to drink. Nevertheless, the springs and seeps in the park are necessary for the survival of many animals. Most reptiles and many small rodents and insects go into an inactive state of hibernation during
2166-607: The higher Mojave Desert and the lower Colorado Desert . The Little San Bernardino Mountains traverse the southwest edge of the park. The earliest known residents of the land in and around what later became Joshua Tree National Park were the people of the Pinto Culture, who lived and hunted here between 8000 and 4000 BCE. Their stone tools and spear points, discovered in the Pinto Basin in the 1930s, suggest that they hunted game and gathered seasonal plants, but little else
2223-632: The higher elevations of the western side of the park. The higher and cooler Mojave Desert is the special habitat of Yucca brevifolia , the Joshua tree for which the park is named. It occurs in patterns from dense forests to distantly spaced specimens. In addition to Joshua tree forests, the western part of the park includes some of the most interesting geologic displays found in California's deserts. The dominant geologic features of this landscape are hills of bare rock, usually broken up into loose boulders. These hills are popular among rock climbing and scrambling enthusiasts. The flatland between these hills

The park's elevation and dry desert air, along with the relatively stable atmosphere in the region, often make for excellent seeing conditions. The park is well known for its naturally dark night skies , which are far away from and largely free of
2793-535: The park. It is forecasted that by 2099, under the high emission scenario, the park will increase in temperature by 8 °F. This would make most of the national park unsuitable for Joshua tree growth. Under the low emission scenario, 80% of suitable Joshua tree habitat could be lost. The desert tortoise population has decreased due to habitat loss and climate change. Lizards in the park are also at risk. Bird species have declined 43% according to studies conducted in 1908–1968 and 2013–2016. Below 3,000 feet (910 m),
2850-407: The region's geology. More than 250 bird species inhabit or visit the park, including resident desert birds such as the greater roadrunner , cactus wren , northern mockingbird , LeConte's thrasher , verdin , and Gambel's quail . About 78 species nest and raise their young within the park. Many migrating species spend only a short time feeding and resting at Joshua Tree, mainly in the winter, as
