Spatial distribution of seriation groups with St. Francis and Memphis Assemblages consisting of Lipo [84] and Phillips et al. [10] samples.

Labels for groups refer to seriation solutions numbered in Fig 9. While each seriation group also includes Holden Lake, this assemblage is removed here for visual clarity. The groups are strongly spatial in their configuration. Interestingly, the Parkin (11-N-1) assemblage falls into groups 2 and 3 suggesting that it served as a central node, possibly indicating emerging social complexity.
