MOUNT HOOD, Ore. (AP) - A dozen rescuers armed with chain saws and other tools are chipping away at a collapsed ice tunnel in hopes of finding a snowboarder buried on Oregon's Mount Hood.
The snowboarder was traveling with five companions when the collapse hit Saturday afternoon. Hood River Sheriff's Office spokeswoman Tiffany Peterson said the search resumed early Sunday and would continue until about 1 p.m. - by which time warming temperatures are expected to increase the risk of avalanche.
Authorities identified the missing man as Collin Backowski, 25, of Pines, Colo. His companions tried to dig him out, but were unable to break through the ice and snow, which Peterson described as being as thick as concrete.
