A tour through the Petrified Forest National Park and Painted Desert is a delightful cruise through some beautiful stratified clays as well as desert animal and plant life. It is also a drop into the past when the glory of Route 66 was in the imagination of many Americans. However there are two views regarding the geologic formations in this area. Besides being a tour guide of the PFNP, this book examines these views. Many beautiful photographs are included for the reader's enjoyment.
