About the Sierra Club
Founded in 1892 by John Muir, the Sierra Club
is America’s oldest, largest and most influential grassroots environmental organization. The Sierra Club’s mission is to explore, enjoy, and protect the wild places of the earth; to practice and promote the responsible use of the earth's ecosystems and resources; to educate and enlist humanity to protect and restore the quality of the natural and human environment; and to use all lawful means to carry out those objectives.
Founded in 1963, the John Muir Chapter is the Wisconsin branch of the Sierra Club. Made up of 15,000 members and supporters, the chapter works to promote clean energy and protect water resources in Wisconsin.
