Grand Canyon Skywalk opens deep divide - Los Angeles Times
This is the main attraction of a planned commercial development for an impoverished Hualapai Indian reservation. Down at the bottom of the article is mention of one big sticking point: H2O.

GRAND CANYON WEST, ARIZ. — Perched over the Grand Canyon close to a mile above the Colorado River, a massive, multimillion-dollar glass walkway will soon open for business as the centerpiece of a struggling Indian tribe's plan to lure tourists to its remote reservation. An engineering marvel or a colossal eyesore, depending on who is describing it, the horseshoe-shaped glass walkway will jut out 70 feet beyond the canyon's edge on the Hualapai Indian Reservation just west of Grand Canyon Village. Buttressed by 1 million pounds of steel and supporting 90 tons of tempered glass, the see-through deck will give visitors a breathtaking view of the canyon. When the cantilevered structure opens to the public next month, it will be the most conspicuous commercial edifice in the canyon. And, if the tribe's plans come to fruition, the Skywalk will be the catalyst for a 9,000-acre development, known as Grand Canyon West, that will open up a long-inaccessible 100-mile stretch of countryside along the canyon's South Rim. The cost of the Skywalk alone will exceed $40 million, tribal officials say.
