A marker, 200 feet to the south, recalls the death of White Buffalo Girl of the Ponca tribe. The death of this child, daughter of Black Elk and Moon Hawk, symbolizes the tragic 1877 removal of the Ponca from their homeland on the Niobrara River to Indian Territory in present Oklahoma.

The Ponca Museum and Library houses artifacts, historical archives, a Tribal Library, and a Community Learning Center, and Culture Department offices.
