Tritely enough, the Presidential signature marked the end of the gestation stage of the Grand Canyon National Park Enlargement Act and the beginning of its life as part of the living law that governs how the Grand Canyon and especially its National Park are to be treated in the political-legal framework of American society. That sentence is not only a trite metaphor but carries major ironies: Enlargement? Or shrinkage? Expansion of a national Park? or an Indian Reservation? And whatever the intent, it is all too clear 40 years later, that much of the Act has been ignored in letter, spirit or both.
