The Michigan Freedom of Information Act (FOIA) provides all persons (except persons incarcerated in correctional facilities) with access to public records of public bodies. Requests to inspect or receive public records from EGLE must be in writing and describe the requested records with enough detail to enable the department to identify and locate the requested records. Some records are exempt from disclosure under the FOIA or another statute and thus will not be provided. A fee may be charged to process your request. Please note that many records are available that do not require a formal FOIA request.

We have been gathering and disseminating information about Michigan’s non-renewable geologic resources dating back to 1837. Much of the published materials about Michigan geology are out-of-print or difficult to access. This document is the result of an effort to make geologic information from agency publications available on the web. This is an ongoing project.
This is a great listing of references and resources for students, teachers, and anyone else interested in better understanding geology in Michigan. Learn about maps, minerals and mastodons just to name a few.
