The Great Lakes Geologic Mapping Coalition (GLGMC) advances the understanding of the three-dimensional distribution of the glacial, periglacial, and proglacial deposits that overlie the bedrock of the glaciated Midwest. It recognizes the fact that several continental glaciations of the last million years have profoundly affected the geology and the natural environment of all eight member States (IL, IN, MI, OH, MN, NY, PA, WI), thereby establishing a commonality of interests among the geological surveys and citizens of these States. In addition, the region has a commonality of demographics, “rust-belt” industry, heavy agriculture, and the Great Lakes. Reaching a fuller understanding of the three-dimensional framework of the glacial sediment of the region is needed to provide regional and National policy makers with the earth-science information required to make wise decisions regarding urban and agricultural land use, the protection of aquifers, and the environmental well-being of the citizens of this geologically unique region.

History:
The Central Great Lakes Geologic Mapping Coalition was formed on December 17, 1998, as a collaboration between the Illinois State Geological Survey, Indiana Geological Survey, Michigan Geological Survey, Ohio Division of Geological Survey, and the U.S. Geological Survey (USGS). The Coalition’s mission is to cooperate in joint geologic mapping investigations and related scientific and technical exchanges concerning the earth sciences (including geology, geochemistry, geochronology, geophysics, geotechnical and geological engineering and collateral investigations) and technical topics of mutual interest. In January 2009, the Coalition was expanded to include the Minnesota Geological Survey, New York State Geological Survey, Pennsylvania Geologic Survey, and the Wisconsin Geological and Natural History Survey. At that time, the organization’s name was changed to the Great Lakes Geologic Mapping Coalition. In 2012, the GLGMC added the Ontario Geological Survey as a non-funded member.

FEDMAP
FEDMAP develops new ways to understand basic earth science processes and produces high-quality, multipurpose digital geologic maps, regional analyses, and multidimensional geologic models. Geologic maps are the primary database for virtually all earth-science applications and issues including mitigation of natural hazards, ground- and surface-water management, land-use management, assessment, and...STATEMAP
The primary objective of the STATEMAP component of the NCGMP is to establish the geologic framework of areas determined to be vital to the economic, social, or scientific welfare of individual States. STATEMAP mapping priorities are established by State Geological Surveys in consultation with a multi-representational State Mapping Advisory Committee. These priorities are based on multiple factors...EDMAP
EDMAP is the component of the NCGMP that funds universities to train the next generation of geologic mappers. EDMAP is a one-year, mentor-guided program designed to teach students geologic mapping techniques through rigorous field mapping. Colleges and universities in the United States and Puerto Rico are eligible to apply through an annual competitive grants process. Every Federal dollar that is...The National Geologic Map Database (NGMDB)
The National Geologic Map Database (NGMDB) is a distributed archive of geoscience information for the Nation. It was mandated by the Geologic Mapping Act of 1992 and is cooperatively built and maintained by the USGS and State Geological Surveys. We welcome you to explore the archive, view the maps, and help us to improve this resource.
