Cascade Chapter Groups

The Sierra Club organizes into groups focused on the environmental concerns within our local communities. The Washington State Chapter encompasses the following groups. For further information on any group, please click the group name.

If you're interested in working on the issues closest to your home, please contact the group chair listed after each group. (If the Group Chair is registered on our site, registered users can log in and click the chairperson's name to use an online contact form. You can also find contact addresses in the online Cascade Crest newsletter.)
