Civil War battlefields stubbornly conceal their secrets and their archaeology remains a buried, largely untapped source of historical information. Douglas D. Scott, developer of methodology that has enabled archaeologists to systematically investigate battlefields all over the world, discusses his recent studies of Civil War battlefields in Missouri, as well as the site of the Centralia Massacre. Retired from the National Park Service, Scott is an adjunct professor of anthropology at the University of Nebraska.
