Open-File Reports
The Kansas Geological Survey maintains a collection of reports and maps that are not published elsewhere and represent research findings conducted in the state. 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.
