Excavations at the Lamb site (11SC24) revealed over 30 pit features that varied in size and shape. Morphological and functional analyses of these pits indicate a range of multipurpose/food-processing, cooking, and storage features. This report concludes with a discussion of community organization at the site. The Lamb site spatial pattern, including communal clusters of deep storage pits and earth ovens, is reminiscent of Late Woodland period settlements in the American Bottom as well as Bauer Branch sites in the central Illinois River valley.
