2006 Investigations at the O. V. Clary Site, Ash Hollow, Garden County, Nebraska Matthew G. Hill, David W. May, David J. Rapson, Thomas J. Loebel, and James L. Theler The O. V. Clary site is one of four late-Paleoindian sites located on the Clary Ranch along a short stretch of Ash Hollow Draw bisecting the property. Limited field investigations in 2005 revealed three stratified late-Paleoindian components (Hill et al. 2006). We returned last summer to further document the geoarchaeological and paleoenvironmental context of the site, focusing on the structure and character of the middle component, which had yielded evidence suggestive of a residential occupation. This work involved geological trenching, paleoecological sampling, and high-resolution excavations of ca. 19 m 2 , increasing the total excavated area to ca. 27 m 2 . All four sites occur within the lower portion of an early- to middle-Holocene fill that is at least 16–17 m thick in Ash Hollow Valley. The surface of the fill is Matthew G.
