A brush fire was burning in a mountainous area of Agua Dulce near Sierra Highway Wednesday afternoon.
The Los Angeles County Fire Department said the blaze, dubbed the #RowherFire, had grown from a couple acres to 250.
The blaze was reported near 11110 W Mint Canyon Road, with a moderate rate of spread. No structures were threatened, fire officials said.
It wasn't immediately clear if there were going to be any evacuations.
Temperatures at 4 p.m. in the area were mild with a light breeze, but fast growth uphill is easy in this kind of terrain, NBCLA meteorologist Anthony Yanez said.
