Eastern Wilderness Act

The Eastern Wilderness Areas Act (P.L. 93-622) was signed into law by President Gerald Ford on January 3, 1975. Built upon the 1964 Wilderness Act, which was written by Howard Zahniser of The Wilderness Society and signed into law by President Lyndon B. Johnson, the Act designated 16 new wilderness areas in the Eastern United States, including 207,000 acres (84,000 ha) of wilderness on national lands in 13 states. Although it was originally untitled, the bill signed by Ford has come to be known as the Eastern Wilderness Areas Act.

While the previous Act created the legal definition of wilderness in the United States, the Eastern Wilderness Areas Act applied only to land east of the 100th meridian west.

In 1964, both the Forest Service and Congress agreed that eastern areas would have qualified as wilderness. However, six years later, the Forest Service opposed congressional designation of new wilderness areas in West Virginia with land use histories of logging. In 1971, it adopted a "purity" interpretation for wilderness designation so that no eastern or western lands with a history of human disturbance could qualify as wilderness.

The Forest Service drafted its own bill as an alternative "to establish a system of wild areas within the land of the national forest system" that would have allowed cutting trees to "improve" wildlife habitat and recreation. The organization described the bill as necessary because eastern areas "do not meet the strict criteria of the Wilderness Act." Members of Congress who championed the Wilderness Act resolved to overturn the misconception that wilderness areas included only those "pristine" in nature. Senator Henry Jackson warned of this "serious and fundamental misinterpretation of the Wilderness Act" and pledged himself to correct the falsity of the so-called purity theory. Senator Frank Church, who had been leader of the Senate debate on the Wilderness Act, observed that "the effect of such an interpretation would be to automatically disqualify almost everything, for few if any lands on this continent—or any other—have escaped man’s imprint to some degree."
