On the banks of the Crawfish River, sits 172 acres of land known as Aztalan State Park.
From 900AD-1200AD, Aztalan was a thriving community of what experts believe, were a "middle Mississippian" tribe of Native-Americans.
When it was dicovered in 1836, very little, if anything was known about the early residents of Aztalan. The only clues to who these people were, was what they left behind. Man-made mounds (platform & conical), farm fields, stockade walls, pottery, and bones.
Today, we know that the early people of Aztalan were primarily farmers, hunters, and fishermen (There have been claims that the people of Aztalan practiced canibalism. While that is more than possible, I haven't read anything that states this as a fact).
However, with answers, come more questions. The main one. What happened to them?
By all accounts, the early residents of Aztalan, "just packed up", and left the area. Why? There are many theories (disease, warring neighbor tribe, loss of a food supply, etc.), but no conclusive answers.
Aztalan was designated a National Landmark in 1964, and placed on the National
Register Of Historic Places, in 1966.
