Open-File Reports
The Kansas Geological Survey maintains a collection of reports, maps, and data that are not published elsewhere. The collection of open-file materials includes graduate theses, preliminary reports, maps, and data. Open-file reports are intended to make the results of research available at the earliest possible date.
The KGS does not guarantee these documents to be free from errors or inaccuracies and disclaims any responsibility or liability for interpretations based on data used in the production of these documents or decisions based thereon.
