Mission Statement

To preserve, educate, and promote the cultural, historical and natural resources of the Cascade Mountain Range and all of the lands and waters that it influences.


Cascade Geographic Society is a non-profit 501(c)(3) educational organization consisting entirely of volunteers. In addition to building a pioneer-era living history village in Rhododendron, preserving the Shanghai Tunnels (and conducting Underground tours), and providing educational programs to schools and groups, we also operate the Breaking Through the Silence Project (A Human Trafficking Education Center).
