NoonCalFire crews gained the upper hand on a fast-moving grass fire that began Sunday evening. As of 7 a.m., today, firefighters gained full containment of the Steele Canyon Fire that burned 70 acres.

Fire crews will continue to labor throughout the day to mop up at the fire scene, CalFire Battalion Chief Barry Biermann said.

The fire began on the 9000 block of Steele Canyon Road, near Capell Valley Road, and was the result of a vehicle crash. A California Highway Patrol helicopter confirmed the fire had burned about an acre at 6:57 p.m.

Steep, hilly terrain provided a challenge for CalFire crews attempting to get into the fire zone and quell the flames.

“The biggest issue that we had was extremely huge slopes,” Biermann said. “The fire ran rapidly up the slope to the ridge point. Because it was so steep, it was difficult getting crews on the line. We were not able to use our bulldozers on a large majority of it. So we had to put hand crews on there.”

Firefighters also had to contend with hot weather and low humidity Biermann said. The fire drew 20 fire engines, six hand crews, four water tenders, and eight air tankers to the area to combat the flames.

No structures were reported lost to the flames and no evacuations were ordered in the area.

Biermann said the fire serves as a reminder that fire season is here and homeowners should make sure that a defensible space, clear of vegetation and debris, is around their homes.
