A mine rescue worker arrives at the entrance of the Crandall Canyon mine in Huntington, Utah, early August 7, 2007. Rescue crews worked through the predawn darkness on Tuesday on ways to find six miners trapped 1,500 feet (450 metres) underground after a coal mine collapsed in central Utah. The mine caved early Monday with such force that U.S. geologists are investigating whether it accounted for an earthquake registered nearby around the same time.
