Crews fighting a wildfire that destroyed the nearly century-old Grand Canyon Lodge and a visitors center were focused Tuesday on stopping the flames from consuming nearby cabins, mule stables and other structures, fire officials said. Firefighters are dealing with a pair of wildfires along the park's less-visited North Rim that together have burned through more than 90 square miles (233 kilometers). Each blaze grew overnight into Tuesday, but fire officials expressed optimism that they had slowed the spread of the White Sage Fire, the larger of the two.
