Endangered American Wilderness Act (Public Law 95-237) is a Federal law, enacted in 1978, that established ten new designated Wilderness Areas in the National Forests of several Western states. Sponsored by Arizona Democrat Morris Udall, the law added approximately 400,000 thousand acres of wilderness in California, Utah, New Mexico, and Wyoming, to the National Wilderness Preservation System. Other sections of the law established three new Wilderness Areas in Oregon and added additional acreage to two existing areas, and ordered the creation of a committee to develop a management plan for 330,000 acres of public land along the Salmon River in Idaho known as the Gospel-Hump area.
