On the western side of the Winnemucca Lake Basin in northwest Nevada is a carbonate tufa mound which contains the oldest petroglyphs (picture-writing) in North America. According to the archaeological record, Native Americans inhabited this area from 14,800 to 13,200 years ago, and also from between 11,300 and 10,500 years ago, and either group is a candidate for having carved the petroglyphs. In any case, this mound of volcanic rock represents a monumental find to give us more understanding of this era of prehistory.
Dr. Benson will be presenting an overview of this find and of the research behind the dating of the petroglyphs.
