Firefighters are battling a small brushfire in Los Angeles' sprawling Griffith Park.

Fire Department spokesman Lauren DeRosier says the blaze had burned about a quarter acre by 4 p.m. Thursday.

DeRosier says the fire is burning downhill from the Griffith Observatory but is not threatening any homes.

A little over a year ago, a fierce wildfire roared through hundreds of acres in the park and forced evacuations in adjacent neighborhoods.

Griffith Park sprawls over 4,100 acres in the middle of Los Angeles.
