The Mart Fire, just the latest in a series of wildfires burning in Southern California this week, has crews working hard Wednesday to gain containment after it burned hundreds of acres the day before.

The fire started Tuesday about 3:18 p.m. north of Highland and east of San Bernardino along Highway 330, according to the incident information page for the fire.

More than 500 firefighters were sent to battle the blaze, which had scorched 902 acres and was 15 percent contained as of Wednesday morning.

The location of the Mart Fire is seen in a map provided on the incident information page for the fire.

Two crew members were injured — one from the San Bernardino County Fire Department was burned, another from U.S. Forest Service stung by bees — and both were taken to the hospital for treatment, firefighters said.

Mandatory evacuation orders were issued Tuesday but later lifted, allowing all residents to return to their homes.

Investigators have not yet determined a cause for the fire.

Meanwhile, three more large brush fires have kept firefighters busy across the Southland.
