In Bismarck, North Dakota, host Mark L. Walberg joins appraiser Ken Gloss at Fort Abraham Lincoln State Park to learn about the books of Elizabeth Custer. Highlights include a 1939 collection from the rescue operation of sunken Navy submarine USS Squalus; a Torino lamp; and two Tlingit Shamanic masks representing a wolf and guardian ancestor that were obtained by the owner's great-grandfather during an 1890 missionary trip to Alaska.
