House In Joshua Tree National Park, California, United States

Below 3,000 feet (910 m), 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). There are areas of such cactus density they 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, 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.
The rock formations of Joshua Tree National Park were formed 100 million years ago from the cooling of magma beneath the surface. Groundwater is responsible for the erosion that created the spheres from rectangular blocks.
