Overview

  • The Dragon Bravo Fire has burned nearly 112,000 acres on Arizona’s Kaibab Plateau and remains just 9 percent contained as of August 1.
  • Towering pyrocumulus formations over the blaze have produced erratic winds that disrupt firefighting operations and fuel rapid growth.
  • The wildfire destroyed the historic Grand Canyon Lodge and forced the North Rim of Grand Canyon National Park to close for the rest of the 2025 season.
  • In Utah, the Monroe Canyon Fire has scorched about 75 square miles since July 13, is 11 percent contained and has prompted evacuations and power outages.
  • Experts warn that persistent low humidity, extreme heat and gusty winds could prolong these megafires and test containment strategies.
