A semi-trailer with flattened tires sits near where a rock fall tumbled from a cliff in Price Canyon last weekend. Rock falls in the canyon are occurring daily and the Utah Department of Transportation scrambles to clear rocks off the pavement. Despite the efforts, rocks may remain on the road for some time. Motorists are urged to exercise caution, particularly when traveling around curves where obstacles cannot be easily spotted. Many blowouts, metal damage and even injuries have been reported due to collisions with rocks on U.S. Highway 6.
