The dataset consists of more than 3,000 sites in Iowa that contain detailed, regional alluvial stratigraphic nomenclature. The dataset is comprised of boring, dug pit, and cutbank descriptions predominately from the Iowa Office of the State Archaeologist, but also from other alluvial studies, including those conducted by the IGS. The majority of these descriptions were first published in documents from the 1990s, but also included data collected in the 1970s and 1980s.
