The Dragon Bravo Fire burning inside Grand Canyon National Park has destroyed dozens of structures, including a beloved and historic lodge.

All wood-burning and charcoal fires, such as campfires and charcoal barbecues, are prohibited. In addition, visitors and residents can only use liquid petroleum appliances like stoves, lanterns or heating devices in an empty area or one that doesn’t have flammable materials within three feet.

Authorities maintained the evacuation zones for the White Sage Fire north of the Grand Canyon as the fire grew expectantly.

Here's what we know about the two wildfires that have destroyed tens of thousands of acres of forest and burned at least 70 structures.

The Grand Canyon Lodge was one of dozens of structures destroyed in a fast-moving wildfire in Arizona over the weekend, the National Park Service confirmed.

The White Sage Fire is located on Bureau of Land Management land, west of Jacob Lake and southeast of Fredonia.

A majority of the damaged and destroyed properties were cabins for visitors, according to data from a preliminary report.

The visitor center and a wastewater treatment plant were among the 50 to 80 structures lost, the park superintendent said. The area was evacuated Thursday.

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.
