Fort Peck Dam [SEP] Representations in art and literature
Fort Peck Dam is probably best known for being the subject of a photograph of the spillway taken by Margaret Bourke-White while still under construction that was the cover photo of the first issue of "Life" magazine on November 23, 1936. Later, the photograph by Bourke-White was used on a United States postage stamp in the "Celebrate the Century" series. The dam is also center-stage in "Bucking the Sun", by the Montana-born writer Ivan Doig, published in 1996. The novel tells the story of the fictional Duff family and their various roles in the mammoth dam project, and in the process describes the working conditions and way of life of the thousands of workers hired to construct the Fort Peck Dam, many of them homesteaders from upriver farms destined to disappear under the waters of the newly formed Fort Peck Lake.
