Authorities say efforts to fight a wildfire by air were put on hold after a drone was spotted near the fire.
KUTV-TV reports all air operations to contain the fire south of Provo were shut down Thursday morning.
Division of Forestry, Fire and State Lands spokesman Jason Curry says people caught using drones over active wildfires can face misdemeanor to felony charges.
Officials say the fire that sparked Tuesday is about 10% contained.
Authorities are investigating its cause.
