A wildfire was burning Sunday afternoon near the Morongo Indian Reservation northwest of Banning, officials said.
The Hathaway fire started just before noon in Hathaway Canyon and had reached 1,300 acres by early Sunday evening. No houses or structures were threatened by the blaze, but authorities said it was sending a plume of smoke toward Big Bear.
About 400 firefighters were fighting the fire, aided by nine air tankers and five helicopters.
Elsewhere, firefighters in L.A. County battled small brush and grass fires in Gorman and Lake View Terrace on Sunday but brought them quickly under control.
A brush fire was reported at 5:31 p.m. in Gorman near the northbound 5 Freeway, just south of Vista Del Largo, and burned through 10.2 acres before firefighters brought it under control by 7:10 p.m., said Ed Pickett of the L.A. County Fire Department.
