The mysterious tunnels of Fort Stevens

Hidden beneath the old bunkers at Fort Stevens State Park in Oregon is a network of long-abandoned tunnels. These labyrinths were well known to soldiers protecting America from German and Japanese military attack during World War II, but these installations have a fascinating history that goes back as far as the Civil War. Today, these dark, damp, winding tunnels seem frozen in time. This story originally aired on Feb. 5, 2004.
