The Loftin site (23SN42) and Cantwell site (23SN389) were the focus of limited rescue archaeological excavation before the construction of Table Rock Reservoir in Southwest Missouri. The work was directed by Professor Carl Chapman of the University of Missouri - Columbia.

The Loftin site was situated on a high terrace overlooking the White River. It included one low platform mound and associated square houses with interior posts (some two and others four posted). The house patterns resemble Caddoan houses of the Harlan and Spiro Phases in Oklahoma. The platform mound was constructed on top of a rectangular earthen wall that surrounded a single, central house structure. The assumption is that the plaform mound sealed an elite or ceremonial structure.

Two radiocarbon dates from the Loftin site are AD 1000 +/- 110 and 1040 +/- 120.
