Ken Johnston find, Flint Ridge, Ohio, identified as a bear head figure worked around a quartz crystal inclusion and worked to manufacture a back lighted translucent "eye"

Vanport chert bear head figure, Flint Ridge, Licking County, Ohio

Bear head figure translucence demonstrated by my desk lamp.

There appears to be a defined-by-the-artist hexagon shaped area around the eye opening with stone removal to allow light passage through the stone.

The translucent "eye of the bear" in sunlight. The natural crystal-lined cavity penetrates the stone to a depth of 2cm.

Side 2. There is deliberate work to expose the translucence on this side of the stone.

Side 2. Yellow line defines area which transmits light to the back of the stone. Black area has been excavated to depth of 7mm in order to get to the desired translucence. Circle-in-circle is end of eye cavity 2cm deep from other side. This stone figure may be considered a "lithophane," a term I coined to describe portable rock art designed to exploit translucent stone features.
