Sand Creek massacre
His second book, "A Misplaced Massacre" (Harvard University Press, 2013), explores the struggles over how the notorious Sand Creek massacre of 1864 should be remembered, beginning in the immediate aftermath of the violence and continuing through the opening of the Sand Creek Massacre National Historic Site. Through archival research and oral history interviews, Kelman documents how National Park Service employees, local landowners, and descendants of victims of the Sand Creek massacre worked together to develop an appropriate memorial for the historic site. "A Misplaced Massacre" has been reviewed extensively.
