Visitors have a view of the Grand Canyon and the Colorado River flowing below from a skywalk extending out over the Grand Canyon and its incomplete building, on the Hualapai Indian Reservation, Arizona February 28, 2012. The tiny Hualapai nation, in a bold move that could serve as a test of the limits of the sovereign power of Native American tribes over non-members, exercised its right of eminent domain last month to take over the management of the site and kick out the non-Indian developer. The dispute over the potentially lucrative Skywalk — which all agree could draw up to 3,000 visitors a day — pits the tribe’s sovereign rights over a site it sees as its economic lifeblood against a developer’s contractual right to manage the attraction for 25 years and share the profits.
