Crews announced Sunday evening that the Canyon Crest Fire has been fully contained at 254 acres.
The fire, which scorched parts of Riverside County bordering San Bernardino County, prompted evacuation warnings when it broke out around 5:30 p.m. on Thanksgiving.
According to CAL FIRE, the fire started near Canyon Crest Drive and Weeping Willow Lane in the Fontana area by the San Bernardino Fire Department.
San Bernardino County Fire first reported crews were on the scene of a 100-by-100-foot spot fire running uphill.
The department soon upgraded the fire from 2nd to 3rd alarm after the flames grew to about 10 acres with a moderate rate of speed. Within the next three hours, the fire grew to about 85 acres and was 0% contained.
Evacuation warnings were issued for the area of the Moreno Valley (60) Freeway east of Country Village Road, south of the county line and west of Sierra Avenue, according to officials.
