Ask Arizona’s Senators to Support the Grand Canyon Centennial Protection Act

Please join the Arizona Trail Association in urging Senator Martha McSally to protect Grand Canyon by co-sponsoring the Grand Canyon Centennial Protection Act (S.3127). The bill, which already passed the House in a bi-partisan manner, was introduced in the U.S. Senate late last year by Senator Kyrsten Sinema.

The Grand Canyon Centennial Protection Act would protect over 1 million acres surrounding Grand Canyon National Park from new uranium mining by making permanent an existing but temporary 20-year moratorium on mining for the Canyon’s north and south rims.

Grand Canyon and the Arizona Trail are pillars of Arizona’s economy, with outdoor recreation generating $21 billion in consumer spending annually, supporting over 200,000 jobs, and sustaining rural communities. The Canyon’s watershed and the Colorado River it feeds provides life-giving water for wildlife, recreationists, and more than 40 million people in the West.

“While mining has played an important role in Arizona’s past, the serious long-term risks to public health, water resources, Indigenous people, and recreational activities on public land far outweigh the prospect of short-term profit from uranium production,” said Matthew Nelson, Executive Director of the Arizona Trail Association. “If any of the 800 uranium mining claims on the Kaibab National Forest south of Grand Canyon were to be developed, nearly 40 miles of the Arizona National Scenic Trail would likely be impacted.”

Arizona residents can participate in the campaign by sending postcards to both Senators online through
