"The Etowah Indian Mounds Historic Site consists of six mounds, three of which are clearly visible: the Great Temple Mound, Lesser Temple Mound, and Mortuary Mound. The Great Temple Mound towered over the community and served as a platform for the home of the priest-chief. Situated between the Great Temple Mound and the Etowah River, the Lesser Temple Mound was originally shaped as a square. Generations of farming softened the edges of the mound, leaving its current, rounded form. The Mortuary Mound is the only mound to have been fully excavated and replaced by a reconstruction. The burial sites and associated artifacts that were discovered within are protected by the Native American Graves and Repatriation Act (NAGPRA) and their welfare governed by the modern-day Muscogee (Creek) people."

A. Native Americans began to cultivate plants for food

This agricultural practice provided a stable food source that could support larger populations and allowed for the development of more complex social structures, including the construction of ritual and ceremonial sites like the Etowah Mounds.
