This 1998 Draft Wilderness Management Plan proposes to set aside large parts of Grand Canyon National Park as wilderness. However, despite large areas being declared "Wild" in the park backcountry management and wilderness areas in Kaibab National Forest (such as the Kanab Creek Wilderness and the Saddle Mountain Wilderness) and in Grand Canyon-Parashant National Monument (such as the Mount Trumbull Wilderness and the Mount Logan Wilderness), no part of Grand Canyon National Park is currently designated as a federal Wilderness area. This contrasts with Zion National Park, where almost the entire park is part of the Zion Wilderness or the LaVerkin Creek Wilderness.
What happened? Why is no part of the Grand Canyon declared as a Wilderness Area?
