This collection ranges from 1912 to 1972 and deals with the professional and social lives of Edmund Rogers and Sarah “Sally” Vaille Rogers. Correspondence, news clippings, conference programs, brochures and more documents serve as evidence of the work Edmund Rogers performed as Superintendent of the Rocky Mountain and Yellowstone National Parks, acting Superintendent of the National Capital Park Service in 1940, and assistant to the Director of the National Park Service. In addition to professional and administrative correspondence, the Rogerses kept letters and memories from their friends throughout the years from Denver and Wyoming. Several guest books are included in the collection, as well as many letters. Correspondence from Edmund to Sally while he was in Washington, D. C., were also kept and show a unique perspective on the workings of federal government. Directories and club minutes show the activities and efforts of Sally Rogers to involve women in the work of maintaining National Parks and supporting employees of the National Park Service.
