Clovis archaeological sites in the central Great Plains are rare. A surface assemblage of Clovis lithics from the Eckles Site in north central Kansas can therefore make a significant contribution to understanding Clovis lithic procurement, landscape use and mobility. The lithic assemblage is unique in that it contains a discarded tool kit and evidence of a newly produced tool kit both made of White River Group silicate that outcrops about 450 km to the west northwest at Flattop Butte in northeast Colorado. A diverse toolkit indicates that the site was a probable camp site near a kill/processing event. Long distance movement of lithic materials to the east southeast and transport of this material in the form of large bifaces is indicated.
