Barbara Washburn was asked to return to Alaska to participate in "Operation White Tower", an attempt at climbing Denali (then Mount McKinley) in 1947. The expedition was funded by RKO Pictures, who planned to use publicity from the climb to attract public interest towards an upcoming film, set in the Alps, "The White Tower." Originally, studio executives wanted to support a trip to Mount Everest, but were convinced by Bradford Washburn that this was geopolitically unfeasible in the immediate aftermath of World War II. Now a mother of three, Washburn was initially hesitant to join the climb, but eventually agreed after consulting the family physician, who assured her a lengthy absence would not harm the children.
