The great purpose is to set aside a reasonable part of the vanishing wilderness, to make certain that generations of Americans yet unborn will know what it is to experience life on undeveloped, unoccupied land in the same form and character as the Creator fashioned it... It is a great spiritual experience. I never knew a man who took a bedroll into an Idaho mountainside and slept there under a star-studded summer sky who felt self-important that next morning. Unless we preserve some opportunity for future generations to have the same experience, we shall have dishonored our trust.
