Heye continued with his interest in Native American culture, funding archeological surveys and excavations in the American Southeast. The field was young, but he supported some of the most professional work of the time. In 1915, Heye worked with Frederick W. Hodge and George H. Pepper on the Nacoochee Mound in White County, Georgia. The work on Nacoochee Mound was done through the Heye Foundation, the Museum of the American Indian (which opened in 1922), and the Bureau of American Ethnology of the Smithsonian Institution. It was some of the most complete work of the time, including numerous photographs. In 1918, Heye and his colleagues published a report entitled "The Nacoochee Mound In Georgia".
