This interview originally aired on In the Moment on SDPB Radio.
Paul Horsted, author and photographer, returns to In the Moment to discuss the fourth edition of his book.
"Exploring with Custer: The 1874 Black Hills Expedition" examines historic photos from General George Armstrong Custer's exploration through western South Dakota. Those photos are presented alongside modern photos taking from the same spots.
In some ways, the new edition is a brand new book. Horsted explains how.
