Fire crews contained a fire in the early morning hours on Friday at the Pima County Fairgrounds.
Firefighters across multiple agencies, including the Corona de Tucson Fire District, Rincon Valley Fire District and Rural-Metro Fire Department, headed to the scene to fight the flames.
Officials say between 150 to 200 pallets caught fire around 4:30 a.m. on April 20 in the northwest section of the fairgrounds, near horses tables and 4-H exhibits.
No injuries were reported in the blaze, and fire crews say the horses, cows, goats, chickens and other animals on the property were never in danger. The fire was not near any of the carnival rides.
Crews kept a close shed full of feed from catching fire before putting out the blaze. The investigation continues into the cause of the fire, and there was no damage other than the scorched pallets.
The fairgrounds are located at 11300 S. Houghton Road, southwest of Tucson.
