Michigan Geological Survey at Western Michigan University houses the biggest collection of geologic maps available for the State of Michigan at the MGS Store. The extent, coverage and type of the maps available can be viewed using the MGS Geoplatform application. Most of the surficial geologic maps are available for the southern part of the lower peninsula while county scale bedrock geologic and bedrock topographic maps are available for northern part of lower peninsula. There are limited mappings done in the upper peninsula of Michigan.
Most of the surficial geological mapping in Michigan have been done through STATEMAP funding. The STATEMAP information sheet shows the status of mapping and funding for Michigan Geological Survey.
