History

The area enclosed by the Park was declared a National Monument in 1936, a Biosphere Reserve in 1984 and finally a National Park in 1994.

The name Joshua Tree was reportedly given by a band of Mormons who crossed the Mojave Desert in the mid-19th century, the tree's unique shape reminding them of a Biblical story in which Joshua reaches his hands up to the sky.

The profile of the Joshua Tree National Park (then a National Monument) was raised significantly in 1987 with the release of the best-selling U2 album The Joshua Tree, the cover of which featured evocative black-and-white photography of the Park's landscape and distinctive trees.

Landscape

Two deserts, two large ecosystems whose characteristics are determined primarily by elevation, come together at Joshua Tree National Park. Below 3,000 feet, the Colorado Desert encompasses the eastern part of the park and features natural gardens of creosote bush, ocotillo, and cholla cactus. The higher, moister, and slightly cooler Mojave Desert is the special habitat of the Joshua tree. In addition to Joshua tree forests, the western part of the park also includes some of the most interesting geologic displays found in California’s deserts. Five fan palm oases also dot the park, indicating those few areas where water occurs naturally and wildlife abounds.

Flora and fauna

While it may at first appear lifeless, the desert supports a myriad of creatures that become active during the evening and early morning. Coyotes are commonly seen near the park roads making their rounds. Jackrabbits and the shy kangaroo rats emerge from their dens in the evenings to forage. Bobcats are less frequently seen, but a lucky traveler might catch one silhouetted against the moonlight. Birds in the park include burrowing owls, vultures, golden eagles, and roadrunners. Lizards, tarantulas, and rattlesnakes may be found among the rocks.

Climate

Days are typically clear with less than 25 percent humidity. Temperatures are most comfortable in the spring and fall, with an average high/low of 85 and 50°F (29 and 10°C) respectively. Winter brings cooler days, around 60°F (15°C), and freezing nights. It occasionally snows at higher elevations. Summers are hot, over 100°F (38°C) during the day and not cooling much below 75°F (24°C) until the early hours of the morning.

Photography

The odd shapes of the Joshua Tree, as well as the dramatic geology and desert scenery, make the park a great place for photographers. As with many areas, photography is best in the early morning and late evening hours.

Rock climbing

The park is one of the most popular rock climbing areas in the world with more than 4,500 established routes offering a wide range of difficulty. Note that there are differing regulations depending on whether a climb is being done within the designated wilderness area or not; check with a ranger for current regulations.

  • Hidden Valley. Located in the northern portion of the park, a short trail leads through boulders to an old cattler rustler's hideout.
  • Barker Dam. Built in the early 1900's to hold water for cattle and mining use, today the area is a rain-fed reservoir attracting local wildlife.
  • Keys View. This overlook, with an elevation of 5,185 feet above sea level, is an extremely popular spot for watching the sunset. On rare clear days the view extends over the Salton Sea to Mexico.
  • Geology Tour Road. Four-wheel drive vehicles are recommended (but not always necessary, check with rangers) for this eighteen mile dirt road. Along this route are numerous interesting geologic formations and trails.
  • Cholla Cactus Garden. A short walk leads through a thick stand of cholla cactus, noted for its especially prickly exterior.
  • Cottonwood Springs. Located near the south entrance of the park, Cottonwood Springs is a desert oasis that offers a respite from the arid lands around it. Willows and birds are found in abundance near this natural spring.
