Brad Gottschalk in the WGNHS map archives.

The Wisconsin Geological and Natural History Survey houses a large number of historical research collections with the potential to be of great interest to science historians, geology researchers, and Survey staff. I am cataloging these collections and converting them to easily used databases and web applications to allow access and to preserve the information. I am also tracking new and ongoing projects carried out by Survey geologists.

Selected completed projects

  • WGNHS Data Viewer (web app): Funded by a grant from the National Geological and Geophysical Data Preservation Program of the USGS, this project makes WGNHS geophysical logs and information about the Survey’s Quaternary core publicly available.
  • Lake Superior Legacy CollectionThe Lake Superior Division operated out of Madison from 1882 until 1905, produced more than 400 field notebooks, collected tens of thousands of hand samples and made 17,000 thin sections. In 2017, the Survey completed a 5-year data preservation project cataloging and providing online access to the material.
  • Mineral exploration in northern WisconsinIn 2018, we completed a project to scan and put online papers donated to us from the E.K. Lehmann and Associates exploration company. The documents detail exploration drilling in northern Wisconsin and provide information about core in our repository from 288 individual drill holes.
