The publication of Fenneman’s two volumes on physiography: The Physiography of Western United States and the Physiography of Eastern United States, was the culmination of over 20 years of work toward formalization of the physiographic regions in the United States. This paper details the relevant works that predate these volumes, the two volumes themselves, as well as briefly describing Fenneman’s career and the continued use of the works 80 plus years post-publication.
