"In this artist rendering provided by Destination Grand Canyon, a glass skywalk is shown extending from the Grand Canyon. An American Indian tribe with land along the canyon is planning to build a glass-bottomed walkway that will jut out 70 feet from the canyon's edge. The skywalk, expected to open in January, is part of the Hualapai Tribe's $40 million effort to turn 1,000 acres of reservation land into a tourist destination that will also feature an Indian village and Western-themed town."
