The reliability of surface assemblages: Recent results from the Gillett Grove site, Clay County, Iowa
Oneota, Rainfall, Surface distribution, Survey
Gillett Grove (13CY2) is a protohistoric Oneota settlement that overlooks the Little Sioux River in Clay County, northwestern Iowa. Work there since 1995 has revealed protohistoric and perhaps late prehistoric Oneota occupations similar to the nearby Milford site. Here, we compare systematic surface collections made in 1998 and 1999 for their similarity in the assemblage properties of size, composition and distribution. Repeated collection in 1999 of some survey units following rainstorms allows us to gauge the reliability of surface records at the site. In general, re-collections by year and by exposure condition differ. A site's surface is a complex sampling domain that a single collection may not adequately sample.
