The Butte-Silver Bow Public Archives will continue its Brown Bag Lunch series on Wednesday, June 8, when Butte Historical Society essay winner Mary McMahon will reprise her talk about her research into a “Walkathon” that offered a $1000 purse to the winner in 1931. She first presented this talk on KBOW’s Party Line in 2021. Walkathons became popular events during the Great Depression, offering entertainment and prizes to participants. In 1931, the event in Butte was held at the Temple Ballroom beginning on April 24 and concluded in July. McMahon will talk about the contest and how the organizers ended up in court. Mary McMahon has been anxious to research and write about the Walkathon for years. She has enjoyed a varied career in accounting, regulatory compliance, and served two terms as the Butte-Silver Bow Clerk and Recorder. She is active in community theater and pursues many creative interests with her family.
