Mineral exploration in northern Wisconsin

Geologist Ernest K. Lehmann accomplished a lot in his 63-year career, including discovering some of the world's largest copper, silver, and gold deposits. Lehmann's company, E.K. Lehmann and Associates, went on several metallic mineral adventures in the Midwest, including northern Wisconsin. This work is encapsulated in paper records donated to the Wisconsin Geological and Natural History Survey, courtesy of his daughter Kate Lehmann. At the link above, readers can explore the collection's maps, sampling results, and reports. Both of the maps have interactive pinpoints. Plus, readers can switch between the Targets and Documents tabs below the maps to browse supplementary materials. The Documents section is particularly insightful as it links to PDFs of several of the reports, images, and other written materials described above. For additional browsing tips, users should click the "i" icon in the top-right corner. The project is led by principal investigator M. Carol McCartney and housed within the Wisconsin Geological and Natural History Survey at the University of Wisconsin-Madison.
