Firefighters in Arizona were tackling two out-of-control wildfires in extreme heat on Tuesday — including one at the Grand Canyon National Park's North Rim that's forced evacuations, road closures and razed a historic lodge and other structures.

The Dragon Bravo Fire, ignited by lightning, destroyed the Grand Canyon Lodge and forced the closure of the North Rim. Initially managed as a controlled burn, the fire rapidly spread due to hot and windy conditions.
