In Michigan, the known archaeological record extends from the present to about 12,000 years ago when humans, and some forms of extinct mega-fauna such as Mastodons, are believed to have first inhabited our Great Lakes region.

Michigan's archaeological resources, however, are largely invisible to the casual observer since they lay buried at varying depths beneath the surface of our modern landscape. Therefore, in order to preserve these valuable and unique resources, and as required by federal and state preservation laws, it is necessary to consider their existence and any potential effects to these resources during the planning of MDOT construction projects.

To fulfill these obligations to the people of Michigan, archaeology at MDOT is performed by professional archaeologists whose credentials meet or surpass federal criteria. MDOT archaeologists also work closely with the Office of the State Archaeologist and the State Historic Preservation Office to ensure that a professional high standard of care is maintained in protecting and preserving Michigan's irreplaceable archaeological resources.
