BIPOLAR FLUTED OBJECT
MESA SITE
NORTHERN ALASKA ABOVE THE ARCTIC CIRCLE
BUREAU OF LAND MANAGEMENT

   This is one of the most unique objects found on the Mesa site. It was found in a late northern Archaic micro-blade feature that dates to approximately 3500 years ago and unlike the other features on this site this one was not associated with a hearth. 120 micro-blades were found in this area. Half of them are made of exotic material brought into the area from somewhere else. This bipolar fluted object is not believed to be a micro-blade core. It's so uniformly flaked that it was apparently made for some specific purpose. No other similar artifacts have been discovered to compare it to so at this time its intended function is not understood.
