Environmental Button

Few episodes in United States history helped forge today’s culture of environmental awareness more than a controversial proposal to build dams within Grand Canyon National Park.
The Grand Canyon’s unique beauty and immense scale have impressed generations of Americans, making the Northern Arizona landmark one of the nation’s most symbolically rich natural landscapes.
The Canyon is formed by the Colorado River, a water system running from the Rocky Mountains into the Gulf of California. The Colorado is one of the largest sources of fresh water and hydro-electric power available to arid portions of the western United States. The river’s resources have been taxed by ever-increasing populations. Dams had already been built on much of the Colorado when the U.S. Bureau of Reclamation proposed erecting new dams within the Grand Canyon in the mid 1960s. The dams were proposed despite the Grand Canyon’s designation as a federally protected National Park (1919.)
