Located in southern California just northeast of Palm Springs, Joshua Tree National Park spans both the Sonoran and Mojave Deserts. The park is huge, weighing in at over 1200 square miles (with 75% of that land designated as wilderness) and encompassing a half dozen mountain ranges. The signature feature of the park is the Joshua Tree...which is actually not a tree, but a species of yucca. A majority of these can be found in the western end of the park interspersed among a variety of fascinating jumbled rock formations.
