In this map, archeologist LeRoy Johnson makes a distinction between what he considers the extent of “Classic Toyah” culture—distinguished by the distribution of the distinctive bone-tempered earthenware pottery tradition—and the wider distribution of the Toyah toolkit. He regards the seven sites on the map as good examples of Classic Toyah culture localities. Four of the seven are located on the Edwards Plateau—East Levee, Buckhollow, Smith Shelter, and Rainey Sinkhole. Graphic from Johnson’s 1994 report on the Buckhollow site, Texas Historical Commission.
