University of Colorado at Boulder Research Associate Craig Lee holds a 10,000-year-old atlatl dart that had been frozen in an ice sheet near Yellowstone National Park. The dart was straight when it was entombed and became bowed from the melting and barely survived being snapped in half by a passing animal.
