Caption: Three stone artifacts from a 13,000-thousand-year-old Clovis-era cache unearthed recently in the city limits of Boulder, Colo. are shown by University of Colorado at Boulder anthropology Professor Douglas Bamforth and Boulder resident Patrick Mahaffy, who owns the property where the cache was found. Two of the more than 80 implements in the cache were shown to have protein residue from now-extinct North American camels and horses.
