Irrigon, Oregon, Columbia River valley, manuported (exotic) stone imported to sites in his locale by prehistoric humans and collected by Dennis Boggs. Figurative interpretation by Ken Johnston. The human face depicted has mid-facial nose prominence and a recessive chin.
Archaeologist and figurative rock art researcher Jan van Es of The Netherlands, whom I regard as an expert in worked quartz artifacts of this type, examined these photos and commented "Remarkable sculpture!" Van Es identified the Boukoulean micro lithic type site at Boukoul, The Netherlands. This figure is made in style also seen in Northern Europe.
