U.S. opinion leaders ask Obama to continue Grand Canyon uranium mining ban
In an open letter contained in an ad published this week in the New York Times, 50 politicians, actors, scientists and public officials urged the Obama Administration extend a 1-million acre mining ban around the Grand Canyon National Park for 20 years.
In 2009 U.S. Secretary of the Interior Ken Salazar issued a federal order calling for a two-year "time-out" from all new mining claims in the Arizona Strip near the Grand Canyon. The lands blocked from new exploration and mining activity includes acreage managed by the Bureau of Land Management and the U.S. Forest Service.
