Omaha author Jeff Barnes introduces The Forts of the Dakota Territory. The program is presented by Deadwood History Inc., and Deadwood Historic Preservation with a grant from the South Dakota Humanities Council. The presentation covers twelve of the territory’s military posts, spanning more than 150 years of Dakota history. “The Dakota forts rank among the most important in the history of the Great Plains, and all with histories tied to the Sioux nation,” said Barnes. His talk includes a brief history of the posts, seldom-heard tales, and many rarely seen historic images and maps. Homestake Adams Research and Cultural Center; 12:00 p.m. Sponsored in part by the South Dakota Humanities Council. The event is free.
