UTAH COUNTY — Crews have contained a Utah County wildfire that investigators believe was sparked by illegal fireworks.

Authorities said the blaze was reported just after 4 p.m. Friday afternoon when Provo City Dispatch received notification of a fire on the mountain just north of Rock Canyon. Fire Crews responded and found the fire spreading up the mountain east of the Rock Canyon Park.

Firefighters from Provo Fire and Rescue, Utah County, the Forest Service, and the Bureau of Land Management responded. Crews were aided by two helicopters and a fixed-wing air tanker. The blaze was reported fully contained later that evening.

Firefighters will continue to monitor the area and extinguish hot spots throughout the night. 

The fire was ignited by illegal fireworks discharged in the area, a news release stated. Two juvenile males were detained and questioned by investigators prior to being released to their parents. Investigators plan to screen the case with prosecutors next week.
