Smithsonian.com has a story about the effort to block the commercialization of the Grand Canyon.  The proposed $500 million development would reside on the rim of one of Earth’s greatest natural treasures. 

When Teddy Roosevelt declared the Grand Canyon a national monument, in 1908, he famously said: “Leave it as it is. You cannot improve on it. The ages have been at work on it, and man can only mar it.” In that sense, the Escalade is a thumb in TR’s eye. Covering hundreds of acres on Navajo Reservation land, it is arguably the most intrusive development ever proposed for the Grand Canyon—a $500 million to $1.1 billion recreation and transport facility featuring a 1.4-mile tramway equipped with eight-passenger gondolas that would carry as many as 10,000 people a day down to the river confluence, with new roads, hotels, gift shops, restaurants and other attractions. The developer—Confluence Partners LLC, a Scottsdale, Arizona-based investment group whose members’ ventures include real estate, resorts and theme parks—says construction of the Escalade could begin as early as this year.
