The fire, first reported about 12:15 p.m. Thursday, prompted officials to issue mandatory evacuation orders for Mojave Scenic and East Canyon drives south from Lone Pine Canyon Road to Buckthorn, Slippery Elm and Mahogany roads.
“It’s pushing away from the town, for now,” said Ryan Carey, an information specialist for Angeles National Forest.
So far, no injuries have been reported and no structures have been damaged, he added.
Relatively low winds and a steady air attack from above were assisting the firefighting effort, Carey said, but those conditions could change later in the day. The “critical period” would be 11 a.m. to 3 p.m., when winds tend to pick up, he added.
Meanwhile, firefighters are working to overcome the steep and rocky terrain where the flames are burning in the Angeles National Forest.
"They’re focusing on doing water drops, putting in hand crews, just suppressing the fire pretty much, hitting it hard," said Shaun Rollman, spokesman with the U.S. Forest Service.
