Excavations in 1980-1981 at sites (32MZ319 and 32MZ380) along Cinnamon Creek Ridge in the Little Missouri River Badlands of McKenzie County, North Dakota, unexpectedly revealed at each locality the presence of one or more deeply buried palaeosols with associated cultural materials. At both sides, 32MZ319 and 32MZ380, multiple palaeosols are present, each of which is terminated by an episode of aeolian deposition. Some 15 radiocarbon dates on these palaeosols establish an incipient chronology for palaeosol development in the study area and permit correlation with other High Plains archaeological complexes. Geological and archaeological data for the two multiple palaeosol sites are summarized.
