Locations and Results of Analyses of Samples Taken in Forest County, Wisconsin - Open-File Report 87-75

Sep 10, 2026

Open-File Report 87-75 compiles locations, stratigraphic information, and semi-quantitative clay mineralogy for samples collected in Forest County, Wisconsin, covering 1977–1979. The report organizes sample identifiers with mapped coordinates/locations, exposure or material descriptions, bulk color and suspended color, and measured depth in feet. Results include grain-size percentage breakdowns (sand/silt/clay fractions) and clay mineral components such as fine clay and related mineral categories, supporting comparative interpretation across sites.
