This site is one of several key sites in the Caddoan Area which Krieger used in the formulation of his classification of Caddoan cultures. It offers, in Mound B, a clear separation of habitation periods by sterile fills and thereby affords a sharp temporal segmentation of culture levels. We believe that we have been reasonably accurate in relating other habitation levels and burials to the four levels of Mound B in working out the picture of the entire site. It now seems desirable to investigate these levels or periods for (a) evidences of continuity of traits and culture patterns, (b) evidences of abrupt interruption of culture or interjection of an entirely new cultural pattern and (c) evidences of distinct culture sequences, resulting either from internal growth and differentiation or from external influences, sudden or gradual. This site may thereby contribute information as to relative depth of Caddoan culture, to the relationship between Gibson and Fulton aspects, and to temporal associations between the various Caddoan cultures and other cultures of the Southeast.
