Feature 112 is a large, oblong basin located in the northeastern quadrant of the Miami Circle. The maximum depth was difficult to estimate, since at least 7 large limestone cobbles were found cemented to the bottom of the basin. Three smaller holes, including one that forms the southern projection of the basin, were found in the bottom of the feature. The limestone cobbles may obscure other small holes. The midden fill excavated from this feature contained animal bone, some marine shell, and at least one sand-tempered plain ceramic sherd.
