The Lone Tree Council is an environmental organization founded in 1978 by citizens of Bay City, MI looking to prevent the Consumer Power Company nuclear construction. Since its inception the Lone Tree Council has focused on other environmental problems such as water pollution in the Saginaw Bay and Tittabawassee River. The collection mainly consists of collected reports from the Environmental Protection Agency and Dow Chemical Company, but also contains educational materials and press statements from the Lone Tree Council.
The Lone Tree Council records consist of materials collected by the organization in response to the dioxins found in the Tittabawassee River and the area surrounding Dow Chemical Company's Midland headquarters.
