At the beginning of the 20th century, these forests were facing the possibility of destruction and vandalism. Consequently, the report was commissioned by the Commissioner of the General Land Office upon the request of the Secretary of the Smithsonian Institution. The report contains a wealth of information on the scenic, geologic, and scientific features of the area. The author provides an overview of the history of the movement to make the region a protected national park. He describes the natural beauty of the area and the unique nature of the petrified logs, which are estimated to be millions of years old and are found in a variety of colors and shapes. Ultimately, the author recommends that the area be preserved and provides detailed suggestions for how this can be accomplished. This book provides a valuable historical record of the efforts to protect this area and makes a compelling case for preserving this unique natural wonder for future generations.
