About the forest
The Sawtooth National Forest was created on May 29, 1905, by the order of President Theodore Roosevelt. It was then called "Sawtooth Forest Reserve" instead of "Sawtooth National forest" And consisted of 1,947,520 acres. It has since been devestated by forest fires, which are thought to have been started by the creators of the film, to spark interest in it.
