Indian tribes have a civil law suit against the federal government which $10+ billions were awarded as the federal government did not forward mineral royalties to tribes for many years. However, tribes have not accepted dollar payments as they want many of their sacred lands returned to their tribes; the Black Hills in South Dakota is principle.
A Navajo girl who lived with my family for a year would say it is "Dolapachan". I agree. She runs a slot canyon tour out of Page, Arizona. It is the canyon you saw in the first Nexium tv advertisements. Go see it. Go see the Geronimo Statue in the Black Hills and give generous donations to complete it!
