Bird figure backs as lithic workbenches
Water bird figure facing left with tool bit protruding from back
Ken Johnston find, Licking County, Ohio.
This is the reverse side with bird figure facing right now.
Both of these birds' backs is carrying a load of quartz crystals which have been worn down by grinding wear. One of the figures presents a cradling cup-like concave surface which has been smoothed from use and the other presents a convex quartz crystal formation with a protruding wear bit. Both figures have unusually flat bases which are stable under movement and pressure. They were found together at an ancient chert quarry and workshop site at Flint Ridge, Glenford, Ohio, and are essentially the same size.
Ken Johnston find, Licking County, Ohio. Interpreted as a bird with well defined wing facing right and another creature with an eye, perhaps a bird, facing left.
The dip seen on the back of the bird here is a cluster of quartz crystals which has been worn down
