Stone tool points to ancient Oregon civilization

Saturday, March 7, 2015by  Jon Osterberg

Archaeologists have dug up an ancient agate scraping tool near Riley, Ore., that dates to around 15,800 years ago – the era of mastodons, mammoths, and camels.
   If its age is confirmed, it would make the Rimrock Draw Rockshelter the oldest human site west of the Rockies, predating the Clovis culture.
   Scientist Scott Thomas discovered the site in when he stumbled across evidence of cooking fires built repeatedly against a lava outcropping. Excavation began in 2011 after 30 ancient stone points were found on the surface.
   Riley is located on U.S. 395, about 23 miles west of Burns. Read The Register-Guard story.
