Nearby wildfires have prompted the cancellation of the yearly show at the Flagstaff Mall, the Arizona Daily Sun reports.
"While the fireworks and location were very safe, prudence dictates a cautious approach to maintain community confidence," Flagstaff Mayor Sara Presler said.
Coconino County reports the Schultz Fire north of Flagstaff is 90 percent contained 10 days after it started at an abandoned campsite in the Coconino National Forest.
The fire has spread over more than 15,000 acres.
Damage estimates exceed $8 million.
