Dated August 1995, the General Management Plan was designed to “provide a foundation from which to protect park resources while providing for meaningful visitor experiences” (NPS, 1995). The plan built upon several earlier park plans including the 1988 Backcountry Management Plan, 1989 Colorado River Management Plan, and 1994 Resource Management Plan. (Subsequent NPS planning documents relevant to the AMP include the 1997 Resource Management Plan and the 1998 Draft Wildemess Management Plan.)
