Joshua Tree National Park is as unique as it is in size. At 1,234 square miles, it is larger than the state of Rhode Island, and contains two separate desert ecosystems (The Mojave Desert and the Colorado or Sonoran Desert).  The Mojave Desert portion is a wonderland of granite boulder formations and a significant variety of vegetation. The Colorado/Sonoran portion of the park is widely the Pinto Basin, a land of wide open sparsely vegetated desert lands. Joshua Tree National Park contains a variety of archaeological sites, historic ranches, mines, and homesteads.
The sites below can be found in my books: Hidden Joshua: The Real Guide to Joshua Tree National Park and Hidden Joshua Tree II.  These books contain GPS coordinates and topographical maps, making it easier to locate the treasures in which Joshua Tree National Park hold.
