Prehistoric Virginia Indians used hammerstones, like these ones found at a site in Orange County in the northern Piedmont, to create stone tools. The rounded sides of a hammerstone were ideal for knocking flakes off of another stone. Archaeologists can tell a hammerstone apart from other natural cobbles by identifying use wear marks, like the dark lines on the left stone in the photo, that do not occur in nature.
