House In Joshua Tree National Park, California, United States

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.
