Rescue workers trying to reach six men trapped in Utah's Crandall Canyon mine found survivable space Saturday after punching a second, wider hole into a cavity where the workers are believed to be trapped and lowering a camera, a federal official said.

The lens will be cleaned and a "horizontal lens" installed so the camera can be lowered again in the hope of getting images of a broader area, Stickler said.
