Firefighters from the Fremont Fire Department and Cal Fire were challeneged by steep terrain and limited access for vehicles, fire officials said.
Fortunately, the flames had a low rate of spread, and winds were relatively calm as of 5 a.m., fire officials said.
The cause of the fire is not yet known but fire officials said preliminary investigation indicates suspicious activity.
