September 12, 1957: "Bernadine (Bunny) Shantz, Walla Walla College student from San Bernardino, Calif., was subject of a feature article in a Seattle newspaper Sunday, dealing with her summertime occupation as a forest fire lookout. Miss Shantz is on Pinnacle Peak, in the Cascades near Enumclaw. It is her second season as a lookout, one of her WWC teachers said. She keeps a pistol for protection in her tower, and soda pop bottles line the tower stairs at night to give her a warning of trouble. 'She's only five feet tall,' her teacher added. A senior majoring in English, Miss Shantz is 26 years old." (Walla Walla Union Bulletin)
