The Mari Sandoz High Plains Heritage Center is located on the campus of Chadron State College in Chadron, NE.
The official website for the center states the "Mari Sandoz High Plains Heritage Center celebrates the life and literature of Mari Sandoz and the culture of the high plains." The Center is also the home of the Coffee Gallery
I have previously written about both Mari and the C. F. Coffee family. The links here are for those who would like to learn more about Mari Sandoz, and her literature.
