Rescue workers say they think there is a void within the caved in roof of the Lucky Friday mine.  They drilled through the debris, ran a camera through and discovered that there is open space.

They drilled some other holes to let fresh air in. Rescuers have been working since the the cave in, on April 15.  53-year-old Larry Marek, and his brother were just finishing up watering down the latest dig, when the roof fell in.  Larry didn’t get out.

Rescuers gave up trying to dig through the debris, because it became more dangerous as they went.  They feared another cave in.  Now they’re trying to dig new tunnels.
