The physiographic regions of the contiguous United States comprise 8 regions, 25 provinces, and 85 sections.[1] The system dates to Nevin Fenneman's paper Physiographic Subdivision of the United States, published in 1917.[2] Fenneman expanded and presented his system more fully in two books, Physiography of western United States (1931),[3] and Physiography of eastern United States (1938).[4] In these works Fenneman described 25 provinces and 85 sections of the United States physiography.[5]
