A wildfire that tore through a historic Grand Canyon Lodge​ had been allowed to burn for days before erupting over the weekend, raising questions about federal officials' decision not to aggressively attack it right away.

Partial blue skies in the morning allowed many park visitors to ignore fires on the North Rim. By afternoon, ashfall made for a different story.

Dozens of buildings inside the North Rim of the Grand Canyon have been destroyed, including a historic lodge, as a chlorine gas leak has forced firefighter evacuations from the Dragon Bravo Fire.

Grand Canyon National Park evacuated Phantom Ranch and areas of the inner canyon after the rapidly growing Dragon Bravo Fire led to the leak of poisonous gas.

About 10 people die at the Grand Canyon every year, CBS affiliate KPHO reported. This is the second death at the park that the park service has reported this year. In May, a 74-year-old man died while attempting to hike from the canyon's South Rim to the North Rim, an approximately 24-mile distance.
