Archives and Special Collections received the research papers of a local historian and mapmaker.

The Nancy Carlsen Research Papers show Nancy's passion for local history, maps, and the Missouri River. The collection is mostly about Clay County cemeteries and the Clay County sites on the National Register of Historic Places. It also includes material about Clay County Preservation Commission, Spirit Mound Trust, Spirit Mound Cemetery Restoration, and River Honoring.

Her papers contain many maps that Nancy created. Enjoy these portions of two of the Clay County SD maps. The first is a shaded relief map emphasizing the Missouri River Valley and the Vermillion River Valley. The second is a color topographic map highlighting Clay County cemeteries.
