This publication is a short history of the National Wilderness Preservation System.
From the Author's Note:
"Through all of this history--and the history of wilderness preservation still being written--the greatest achievement is that of tens of thousands of spirited people who, as volunteers, have indeed fought, in Bob Marshall's immortal phrase, "for the freedom of the wilderness." Our National Wilderness Preservation System is, foremost, their gift to the Earth and to future generations."
