This small, finely-worked, symmetrical, black chert graver has been created by the sequential removal of dozens of flakes in a patterned manner. The ventral side is a smooth flake bulb. Found in cemented reddish-tan sands at a depth of nearly 4 m in the Lower Yermo Formation. There is no possibility that this refined object could be a "geofact" produced by natural geologic processes. Coated with powdered aluminum. D. Griffin photo
