[[Wilderness]] areas are part of the [[National Wilderness Preservation System]], which consists of federally managed lands that are of a pristine condition, established by the [[Wilderness Act]] (Public Law 88-577) in 1964. The National Wilderness Preservation System originally created hundreds of [[List of wilderness areas of the United States|wilderness zones]] within already protected federally administered property, consisting of over 9 million acres (36,000&nbsp;km<sup>2</sup>).
