For more than 150 years, the hills and cedar breaks of western Travis County have been populated by the Cedar Choppers, migrants from Appalachia who made a living cutting and selling cedar logs. Who are these people? Author Ken Roberts set out to answer that question after a chance encounter with three young cedar choppers beneath the Tom Miller Dam. Roberts will share his insights from his new book, “The Cedar Choppers: Life on the Edge of Nothing,” during an author talk at the Austin History Center. Light refreshments will be served and a book signing will follow the event, which is free and open to the public.
