Grand Canyon

June, 1966

Sierra Club published full-page newspaper ads in the New York Times and Washington Post against building a dam that would flood the Grand Canyon. The next day, the IRS hand-delivered a suspension of the Club’s tax-exempt status. This action boosted the Club’s prestige and membership and helped in the fight to save the Canyon. The ad in question said simply, “This time it’s the Grand Canyon they want to flood. The Grand Canyon.”
