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

A wildfire that leveled a historic lodge and a visitors center on the Grand Canyon’s North Rim grew rapidly more than a week after it began as firefighters pushed ahead Monday with efforts to slow its spread.

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 (NPS) confirmed.
