DENVER – Landscapers were digging a hole for a fish pond in the front yard of a Boulder home last May when they heard a "chink" that didn't sound right. Just some lost tools. Some 13,000-year-old lost tools. They had stumbled onto a cache of more than 83 ancient tools buried by the Clovis people — ice age hunter-gatherers who remain a puzzle to anthropologists.
The home's owner, Patrick Mahaffy, thought they were only a century or two old before contacting researchers at the University of Colorado-Boulder.
"My jaw just dropped," said CU anthropologist Douglas Bamforth, who is leading a study of the find. "Boulder is a densely populated area. And in the midst of all that to find this cache."
