The Sierra Club is the oldest, largest, and most influential grassroots environmental organization in the United States. Since it was founded in 1892 by John Muir, the Sierra Club has been working to protect communities, wild places, and the planet itself. The Sierra Club has helped to establish many National Parks and a National Wilderness Preservation System. The Sierra Club is divided into many regional chapters and those chapters are further separated into individual groups that focus on issues in their local area. The Northern Rockies Chapter of the Sierra Club is concerned with issues involving all of Idaho and eastern Washington. It is composed of five groups with the Middle Snake Groups located in Boise, Idaho; the Eastern Idaho Group in Pocatello, Idaho; the Sawtooth Group in Twin Falls, Idaho; the Upper Columbia River Group based out of Spokane, Washington; and the Palouse Group located in Moscow, Idaho. The Palouse Group encompasses central Idaho and southeastern Washington.
