The artifacts found, with fire-cracked rock and ceramics dominating the assemblage, suggests that 21AN106 was a processing site. Direct evidence for wild rice use there is provided by the phytoliths identified in food residues from the ceramic sherds. Based on the presence of phytoliths, it appears that the inhabitants also ate corn, squash, and other plants, but there is no evidence that these were grown at the site. Finally, the location overlooking Rondeau Lake, where extensive wild rice beds still exist, suggests that this attracted Middle Woodland peoples to the area. It is likely that the site was used repeatedly on a short-term, seasonal basis.
Wild rice is harvested during the late summer and early fall.
Frequency of occupation was probably determined by the size of the wild rice crop in Rondeau and other lakes along Rice Creek. This may have varied with time because of local and regional environmental factors. Therefore, 21AN106 may not have been inhabited consistently over the years. This site, like many others in the Rice Creek drainage basin was occupied during a period when lake levels were relatively high and wild rice would have been plentiful. In addition, other plant and animal resources would have been available, making the area a particularly attractive one to Middle Woodland peoples.
