Wildfire activity has intensified across the western United States, as consecutive days of hot, dry and windy weather have fueled flames in Utah, Arizona and elsewhere as new fires popped up across the region.
The largest blaze, the Cottonwood Fire, was burning in rugged terrain in southwest Utah. It ballooned Saturday to more than 144 square miles (373 square kilometers) after marching through canyons and mountainsides, destroying part of a ski resort and other summer cabins along the way.
