In 1936, the conservationist Bob Marshall made a list of forty-eight forested areas in the United States that exceeded three hundred thousand acres and that remained roadless — that is, relatively pristine. Evidently, he considered three hundred thousand acres to be the minimal size of a true wilderness.

“We would like to point out that the 300,000 acres is not a roadless area in any pioneering sense,” Marshall wrote in the magazine Living Wilderness (with co-author Althea Dobbins). “Actually, a 300,000-acre tract is only about 21½ by 21½ miles, something which a reasonably good walker could traverse readily in a day if there were a trail.”
