Relic thefts 'huge crime problem' in U.S. parks

Some visitors to Badlands National Park spot a fossil and take it home as a souvenir. Sometimes college students studying the 244,000-acre park's natural history assume it's OK to take a specimen for further scrutiny.

A bigger problem, though, is the looting of artifacts found in the South Dakota park's rich fossil beds by thieves who plan to sell them online or to galleries or collectors.
