Crews were fighting the fire on the ground and in the air until they had 100 percent containment by Sunday evening.
The fire started at about 4 p.m. Saturday in an area known as the San Timoteo Badlands off Highway 60. It quickly spread as it moved uphill, fueled by dry winds and 90-degree temperatures.
About 945 acres were charred. No structures were threatened. Officials said at one point it had the potential to burn up to 1,500 acres.
Smoke from the burning brush forced the California Highway Patrol to close a stretch of Highway 60 between Theodore and the 10 Freeway.
All lanes of the 60 Freeway have since reopened.
"Shutting it down allowed us to protect drivers through the area as well as allow us to function and make an attack on the fire," explained Riverside County Fire Department Chief Dorian Cooley.
The cause of the fire was under investigation.
