A society that could develop a site of this type is believed to have had a well-organized political system with tribal leaders more than likely residing in regional centers such as the Lake Jackson site. The remains of important tribal members have been found at the site, with a rich array of burial objects including elaborate items such as copper breast plates, shell beaded necklaces, bracelets, anklets and cloaks still in place. These exotic artifacts indicate religious and trading ties with other large, pre-historic Indian ceremonial centers in the southeastern United States. There is evidence that the Lake Jackson Indians participated in a southeastern socio-religious complex known to archaeologists as the 'Southern Cult' or 'Southeastern Ceremonial Complex,' which flourished around A.D. 1200. The area was probably the political and religious center for Indians of this location during the period A.D.1200 to A.D.1500.
The rich history of Lake Jackson Mounds is brought to life with replicas of actual artifacts found by archaeologists during excavations at this site. Exhibits drawing further connections to the site can be seen on the far side of the large pavilion.
