Series I: Horace Kephart Papers (1926 March 6-1973 January 23) houses correspondence, photographs, publications, newspaper clippings, and other materials illustrating Kephart's work in the Great Smoky Mountains. In the interests of clarity, both original manuscripts and photocopies of Kephart's published articles are included in this series. Of particular interest are the items documenting the naming of Mt. Kephart and the memorial associations organized to honor Kephart's memory.

Series II: George Masa Papers (1930 August 24-1979) houses correspondence, notes, publications, and photographs documenting Masa's career in the Smokies. Among these materials are several of Masa's rare original photographs and letters.

Series III: Research Papers and Publications Regarding Horace Kephart and George Masa (1882-2009 October 30) houses a wealth of material showing Margaret Radcliffe Gooch's and Jim Casada's research into both Kephart and Masa's lives and careers. Gooch was friendly with both men, and her papers include a few of her personal recollections of them in addition to a body of notes on secondary sources. Casada created the majority of his material while researching such publications as articles, his introduction to Kephart's Camping and Woodcraft, and an unfinished Kephart biography. Among these items are biographies of Kephart's father and grandfather, articles published by various of Kephart's relatives, correspondence with academic institutions and individuals who knew Kephart, and bibliographical records of published materials relating to Kephart's work in the St. Louis Mercantile Library and in the Great Smoky Mountains.
