This digital data release presents contour data from multiple subsurface geologic horizons as presented in previously published summaries of the regional subsurface configuration of the Michigan and Illinois Basins. The original maps that served as the source of the digital data within this geodatabase are from the Geological Society of America’s Decade of North American Geology project series, “The Geology of North America” volume D-2, chapter 13 “The Michigan Basin” and chapter 14 “Illinois Basin Region”. Contour maps in the original published chapters were generated from geophysical well logs (generally gamma-ray) and adapted from previously published contour maps. The published contour maps illustrated the distribution...

A compilation of drill core logs and thin section notes, including well abandonment reports, drill hole location maps, and associated notes, from Minnesota Geological Survey Precambrian geologists. These logs and notes were scanned using NGGDPP FY22 support and will support future investigations of Precambrian geology by MGS Precambrian geologists, other statewide stakeholders, industry, and universities.

Hand specimens of rocks collected in and around Marathon County as part of a bedrock mapping project in the 1970s and 1980s. Specimens were collected by P.E. Myers and UW-Oshkosh geologist Gene LaBerge as part of the field work supporting WGNHS publication Information Circular 45: Precambrian Geology of Marathon County, 1983. The collection consists of about 1500 specimens taken from approximately 580 outcrop locations.
