Calico Early Man Site, Mannix Basin, Yermo, California / h)percoiralumtip4
"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 object could be a geofact produced by natural geologic processes. Coated with powdered aluminum" [Fred E. Budinger Jr., Calico Project Director, Calico Early Man Site, www.calicodig.org].
