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 Grand Canyon Lodge and other buildings were destroyed by the Dragon Bravo Fire, which began as a controlled burn overseen by the National Park Service.

The lodge itself told a key part of history for both the Grand Canyon and the National Park Service.
