About Us
The Straits of Mackinac Alliance is a membership organization of individuals and businesses who want to protect and restore the natural resources of the Straits of Mackinac and adjacent waters of the upper Great Lakes. Specifically, we seek to eliminate the threat posed by crude oil and natural gas pipelines under the Straits of Mackinac. We also hope to continue to be viable long after Line 5 is history to foster climate resiliency and rational development of the Straits area.
