At Lake Jackson Mounds Archaeological State Park, the entire complex was composed of seven earthen temple mounds that were part of the village and trading area. Pottery and stone tools plus the location and shape of the existing mounds have been used to identify the age and culture of the site. There is evidence that the Lake Jackson Native Americans participated in the Southeastern Ceremonial Complex since a broad regional similarity of artifacts, iconography, ceremonies and mythology of the Fort Walton Period were connected there.
The remains of important tribal members and high-status burials have been found at the site. Burial goods such as salt, shells, stone celts and pearls used for hair and clothing adornment suggest trade with other Mississippian sites such as Etowah, Spiro and Moundville. The presence, or absence of, exotic copper in a burial would be a designation of status. The hawkman dancer style copper breast plates found in some burials are some of the most distinctive iconography of the Southeastern Ceremonial Complex.
