Fire crews expected to continue using aircraft to support ground crews on northern Arizona wildfires, according to InciWeb, a wildfire tracker.

Two fast-moving wildfires—the Dragon Bravo and White Sage fires—have scorched more than 45,000 acres, destroyed the iconic North Rim lodge and dozens of structures, and led to long-term closures in the Grand Canyon.

A lightning-caused wildfire known as the Dragon Bravo Fire is burning on the North Rim of Grand Canyon National Park. The fire is currently estimated at approximately 10 acres and is located south of the Basin near the W1 Road.

The fire that burned for days on the North Rim of Grand Canyon before it became uncontrollable was "expertly handled," the National Park Service said.

Wildfires have forced evacuations at two U.S. national parks in the West as summer monsoon storms increase lightning in the region.

Wildfires at U.S. national parks are prompting evacuations and causing major disruptions as the effects of climate change are impacting the tourism season.

A water treatment facility at the North Rim had been compromised by the fire, causing chlorine gas to fall to the bottom of the Canyon.
