Microsculpture possibilities: skull, scream and grin masks on piece of exotic material from the Columbia River valley
Dennis Boggs find, Irrigon, Oregon, along the Columbia River
After a couple of years communication with archaeologist Jan van Es of The Netherlands, I have come to recognize some of the microlithic techniques of stonework and their visual hallmarks. This stone is of highly unusual stone material in the Dennis Boggs portable rock art collection.
I used my Bausch & Lomb 10x lighted scope to examine the pebble to confirm traces of intentional stone removal to create the images. It has three likely areas of stonework, creating three possible "human mask" images on the one pebble. Rock art scholars will need to develop the scientific skills to confirm intentional workmanship on objects such as this. Anomalies which go unexamined (unexplained) by archaeology leave its public looking elsewhere for cogent explanations of their finds and observations. Above, the scream mask and the grin mask are seen in the same view. The mouth of the scream mask is the nose of the grin mask while they share the same left eye.
