Abstract

Flotation-recovered plant remains from a series of 11 sod block samples, 7 features, a limestone concentration, and a mass of organic debris provide insights into the construction of Monks Mound. The presence of uncarbonized seeds exclusively of annuals (other than those of perennial elderberry and wild grape, which probably represent food remains) indicates that the construction of Monks Mound was relatively continuous. The presence of quillwort megaspores and other indicators of wetlands provide additional data on how Monks Mound was constructed and where some borrow and/or sod blocks were likely obtained to construct at least part of this monument.
