Tool Time

Ice Age Tool Cache Found in Colorado Yard: Discovery News: "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."
