Fifty years ago today (Sept. 3) President Lyndon Johnson signed into law The Wilderness Act, which preserves lands that are some of our greatest national treasures. The lands are left in, or restored to, their natural state and man is just a visitor to them who leaves no imprint. As such, Wilderness offers unparalleled chances for solitude.
Can you imagine being the only one for as far as the eye can see, like this hiker in Andreafsky Wilderness in Alaska? (Well, except for the photographer.) More than half of the acreage in the National Wilderness Preservation System lies in Alaska.
