The Central Great Lakes Geologic Mapping Coalition
Abstract
The State Geological Surveys of Illinois, Indiana, Michigan, and Ohio joined with the U.S. Geological Survey (USGS, under the Earth Surface Dynamics Program) to form the Central Great Lakes Geologic Mapping Coalition. These four States have a similar geologic heritage and need to address common societal issues about land and water resources, the environment, and geologic hazards. By pooling their expertise and resources, the five Geological Surveys can address these issues more effectively than could any one survey.
