Twenty-five artifacts are classified as discoidal scrapers. Again, as
noted in the case of side scrapers, the dividing line between some of
these and certain utilized flakes is somewhat arbitrary. Generally
these artifacts are steeply flaked, by percussion, on both faces and
all edges, giving them a rather rounded appearance. The largest is 2½
× 2¼ inches, the smallest ¾ × 1½ inch. Quartzite and flinty materials
show about equal usage.
