Landslide Closes SR 14 in Utah

Landslide blocks SR 14 east of Cedar City, UtahA large landslide has closed SR 14 east of Cedar City, Utah. UDOT expects that the road will be closed for up to 2 weeks for cleanup and to ensure that the slope is safe. Boulders up to an estimated 20 tons are now blocking the road and will likely need to be blasted down to a smaller size. A UDOT spokesman interviewed on the video shown after the break estimate the size of the slide at 700 to 800-ft long and 10 to 12-ft thick.

Oregon man laments losing his house to fire after a landslide knocked it off its foundationThis is definitely the season for landslides, mudslides, debris flows and other mayhem in Oregon and elsewhere in the pacific northwest.
