This large biface was recovered from the Pawnee Indian Village site in Republic County and donated to the Kansas Historical Society. It is made of Smoky Hill silicified chalk, a type of chert that outcrops in western Kansas and north into Nebraska. It may have been stored for future use (what archeologists call a cache), meant for trade, or had some other significance we today do not know. The Pawnee Indian Village is listed in the National Register of Historic Places. A museum was built over one of the lodges that was then excavated, leaving the exposed floor visible.
