This vector polygon dataset represents the current gross extent of Congressionally-designated wilderness for the National Park Service, Alaska Region. The Congressionally-designated wilderness boundaries defined in this dataset are external wilderness unit boundaries. They do not exclude lands (e.g. inholdings) that fail to meet the Alaska National Interest Lands Conservation Act (ANILCA) definition for "public lands" (i.e. Public Law 96-487, 94 Statute 2371, Title I, Section 102(3 A-C), December 1980).
