Before this was done, Clarence Johnson, a historian for the Civilian Conservation Corps directed excavation of the north half of Midden B.

The results of these investigations were published in 1945 by James A. Ford and George I. Quimby, entitled "The Tchefuncte Culture: An Early Occupation of the Lower Mississippi Valley".

In 1986, Richard Weinstein and Charles Pearson of Coastal Environments, Inc., and Dave Davis of Tulane University excavated portions of Midden A as part of a field school for the Louisiana Archaeological Society.

In 2000, archaeologists from the Regional Archaeology Program mapped the site for a National Register of Historic Places nomination.

Their houses were probably temporary circular shelters having a frame of light poles covered with palmetto, thatch, or grass mixed with mud.

Their main food included a variety of seafoods, such as clams, alligators, and fish, but surprisingly not crabs or crawfish which were likely to have been available and abundant.
