Goodreads asked Gerald Hickman:

Where did you get the idea for your most recent book?

Gerald Hickman When I worked as a Park Ranger in 2002 and 2003, I realized that my view of the history of the park was somewhat new and different than many of the accepted books on the subject. The idea was that I could write an account of the event that might be of interest to History classes, students, and people who specialize in study of the Park and its history.
Thus, I began the book centered on the Ranger Talks given daily to the visitors and the book expanded to include the 2 years effort of the Government resulting from the original event.
