THE BOUNDARY OF GRAND CANYON NATIONAL PARK
The Park boundary can be divided into 16 major segments, each with its own history and formal, legal justification. I have labelled them A through P, starting at the Paria River junction and proceeding clockwise. Most of the posts under this topic deal with a specific segment, including text, sources, and maps. There are also several more general posts referring to the boundary, which I have collected together at the beginning.
I have given the boundary that abuts the Hualapai Indian Reservation and the boundary of the Reservation itself special treatment in several posts, which appear in a section by themselves.
EACH TOPIC IS PLACED AT THE LEFT MARGIN.
