Great Lakes Geologic Mapping Project
The objectives of the U.S. Geological Survey (USGS) Great Lakes Geologic Mapping Project are to improve understanding of the geological framework of the Great Lakes region of the United States, and to improve understanding of coastal dynamics in this region. The project includes several overlapping geomorphic and geologic framework elements and associated scientific problems for which an innovative mapping approach will provide societal and scientific benefits. The geologic maps and associated products will: (1) improve regional understanding of Quaternary stratigraphy, interpretations of glaciations, landscape evolution, and natural resource distribution; (2) improve understanding of regional groundwater systems; (3) improve understanding of regional bedrock topography; (4) provide insights into coastal change processes; and (5) improve understanding of regional Paleozoic stratigraphy, and improve prediction of the distribution of certain lithologies that are essential to mineral and energy resources.
The USGS Great Lakes Geologic Mapping Project is divided into four Tasks. For publications and other products associated with this project, please see the USGS Staff Profiles of individual project staff members listed for each Task.
The study area of the project is depicted on the following web page: https://ngmdb.usgs.gov/mip/
The USGS Great Lakes Geologic Mapping Project is funded by the USGS National Cooperative Geologic Mapping Program [https://www.usgs.gov/core-science-systems/national-cooperative-geologic-mapping-program]. This project works closely with State Geological Survey partners of the Great Lakes Geologic Mapping Coalition [https://www.usgs.gov/core-science-systems/national-cooperative-geologic-mapping-program/science/great-lakes-geologic?qt-science_center_objects=0#qt-science_center_objects].
