Sierra Club Plateau Group

The Sierra Club is one of the oldest and most influential grassroots environmental organizations in the United States. The Grand Canyon (Arizona) Chapter was formed in 1966 in order to focus attention on stopping dams in Grand Canyon.

The Plateau Group of Northern Arizona is an extension of the Grand Canyon Chapter with a heavier local focus on the Northern part of the state. Our work to protect the Colorado River, Colorado Plateau and Grand Canyon National Park continue today and have been joined by a number of programs to safeguard other areas and issues.
