"A wilderness . . . is hereby recognized as an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain."
So boldly declared Congress in 1964, when it voted nearly unanimously to protect some of our nation’s most treasured areas. September 3 marks the 51st anniversary of the Wilderness Act, which established the National Wilderness Preservation System and protected 9 million acres of pristine land.
