Wyoming Chapter


Welcome to Sierra Club Wyoming Chapter 

Sierra Club Wyoming Chapter members celebrate the 50th anniversary of the Wilderness Act by going to the wilderness.Founded in 1894, the Sierra Club is America’s largest, oldest and most influential grassroots environmental organization. Our mission is to explore, enjoy and protect the planet.

Wyoming is the home of some of the most spectacular national parks, remote wilderness, abundant wildlife, and undeveloped landscapes in the entire country.  Wyoming is also rich in energy and mineral resources, and our economy, in recent decades, has been dependent on coal, natural gas, and oil development.   Sierra Club Wyoming Chapter works to protect our phenomenal natural environment from industrial development while promoting the transition in Wyoming to clean energy and a sustainable economy for the future.

Our strength lies in our members and supporters.  Please become a new member or renew your membership today. We also invite you to get involved and we welcome your donations to support our important work.

Thank you for all you do to protect Wyoming’s environment.
