This is a partial representation of a geologic map of the Surficial geology of the glaciated region of the US. The blue dashed lines represent glacial and glaciofluvial features, roughly outlining the boundary of the glaciated region. The black outlined states represent the eight member states of the Great Lakes Geologic Mapping Coalition. 

This chart depicts funding amounts in US dollars awarded by the NCGMP's STATEMAP program by state for the time period between 1993 and 2025. Paler hues indicate lower funding amounts (with white being no funding), where darker hues show higher funding amounts. 

The screenshot was captured from the 3D web viewer tool created by Illinois State Geological Survey (ISGS).

This screen clipped image was generated with the Illinois State Geological Survey's 3D viewer. This map shows the surficial geology of Boon County, Illinois above a generated cross section along the red diagonal indicator line.

This graphic shows the distribution and total US dollar amount of funding received by each GLGMC member state between 2009 and 2025 since the Coalition has been part of the National Cooperative Geologic Mapping Program.

This is a partial representation of a geologic map of the Pre-Quaternary geology of the glaciated region of the US. The blue dashed lines represent glacial and glaciofluvial features, roughly outlining the boundary of the glaciated region. The black outlined states represent the eight member states of the Great Lakes Geologic Mapping Coalition. 

This image shows a street map within McHenry County, Illinois (above). The red line indicates the location of the geologic cross section (below). The red line shows an area of proposed development and the cross section indicates the existence of a sensitive aquifer along that locator line. 

This map shows the generalized glaciated terrain of the state of Illinois. For more information, visit the Illinois State Geological Survey website.
