This Charter between the Illinois State Geological Survey, the Indiana Geological Survey, the Michigan Geological Survey, the Ohio Division of Geological Survey, and the U.S. Geological Survey  records the Parties' desire to cooperate in joint investigations and scientific exchanges concerning the earth sciences (including geology, geochemistry, geochronology, geophysics, geotechnical and geological engineering and related investigations) on topics of mutual interest. This agreement is specifically undertaken to advance 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 four States - Illinois, Indiana, Michigan and Ohio - thereby establishing a commonality of interests among the Parties and citizens of these states. The Parties have agreed that reaching a fuller understanding of the three-dimensional framework of the glacial sediment of the region is needed to provide regional and national policymakers 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.
