The History of Badlands National Monument and the White River (Big) Badlands of South Dakota
by Ray H. Mattison, Robert A. Grom
About the author
Robert A. Grom is known for co-authoring The History of Badlands National Monument and the White River (Big) Badlands of South Dakota with historian Ray H. Mattison. The book grew out of his work gathering photographs, maps, and historical material connected with the park, and it reflects a strong interest in making the Badlands understandable to visitors and history readers alike.
Available historical notes on the book describe him as a former Chief Park Naturalist at Badlands National Monument. That background helps explain the book’s practical, interpretive feel: it does not just recount dates and events, but also connects the landscape, its fossils, and its human history.
Reliable biographical information about his wider life and career is limited in the sources I could confirm, so this overview stays close to the record that is available. From that record, he stands out as a public-facing park historian whose writing helped document one of the American West’s most striking landscapes.
