Ancient Monuments of the Mississippi Valley is the landmark survey by E. G. Squier and E. H. Davis of the earthworks and mounds built by the indigenous peoples of the eastern United States. Issued as the first volume of the Smithsonian Contributions to Knowledge, it presents careful surveys, maps, and descriptions of hundreds of prehistoric sites.
The book is a foundational document of American archaeology, providing the first systematic record of mound-builder structures, many since damaged or destroyed. Though some of its interpretations are dated, its meticulous fieldwork remains invaluable to scholars. For students of pre-Columbian North America and the history of archaeology, this classic survey is an essential source on the monumental architecture of ancient native cultures.
