The 5,000-acre Dragon Bravo Fire continues to rage through Grand Canyon National Park's North Rim. Initial assessments estimate that 50 to 80 structures have been destroyed by the blaze so far.
Wildfires can burn and spread differently depending on what vegetation they burn. The two fires in northern Arizona have varied landscapes. Ponderosa pine trees grow near the North Rim of the Grand Canyon and can live for hundreds of years.
